Really irritating and annoying cuz you think that something’s wrong and go to check your tank and nothings actually wrong. pH probe didn’t work correctly either one that came with the package was defective, won’t measure ph properly or recalibrate properly so it’s giving the wrong readings, ### 2/5 — Wifi outlets connectivity issues *2024-07-06, version 3.0.5* Since last update I'm unable to connect any wifi powerstrip. 👎🏽 ### 3/5 — Languaje…. *2024-06-25, version 2.6.4* Products in Mexico are booming, however it would be great if it were offered in a Spanish version ### 2/5 — Works well enough *2024-04-24, version 2.6.4* This app does not feel like it was designed for end users. But rather designed by a tech person, possibly with a Windows/networking background, for a certain type of tech person. The app requires the user to log back in with username and password every 30 days. Really? Every 30 days? For some wave pumps? Seems much more like an designer’s/team’s design flex rather than practical and useful for users. The controller nearly always remains connected to the cloud. When a connection is lost for 15 mins +/- a notification from the app is displayed. Best use of this is it lets me know WiFi is being wonky. The function of the pumps are unaffected. When WiFi is down the app does allow pump connection via blue tooth. I like the products associated with the app, but the app is “meh.” Two stars. One star lost because of the GUI. An additional two stars lost because of the forced log out and reauthorization every 30 days. ### 4/5 — Good peace of mind *2023-10-16, version 2.6.3* Got a water level sensor and a temperature probe about a year ago and I really like knowing my tank’s (freshwater) status and that it’s safe, love the alert features too, only downside is sometimes you have to sign back into your account when you open the app which I could see potentially being an issue. ### 3/5 — Watch app coming? *2023-09-16, version 2.6.3* Would be great to have some functionality on a watch app…even if only to switch modes to feed or water change. Otherwise a good app. ### 3/5 — No longer works on my iPad Mini 2 *2023-01-22, version 2.5.0* Since the app was updated to only run on IOS 15.0 or higher, it will no longer work on my older iPad Mini since it’s on IOS 12.5.6 and is the highest it will go. I had it working perfectly fine about a month or 2 ago and now my iPad is useless since I only used it for controlling my Hydros Control 3. Pretty disappointed honestly and wish older devices were supported longer since this iPad is in mint condition. ### 4/5 — Better than alternatives imo *2022-03-13, version 2.3.1* Hydros is new, and rn generally for people that are ok with both sides that coin. Love the cloud connect. Especially as I travel. Frustrated that rn the app is having issues loading my collective, "waiting for config," but the web app works great. Am excitedfor / hopeful Coralvue will deliver on: - More 3rd party support. Love that wave engines can plug right in and are controlled through the collective. Let's get more of this with return pumps, skimmers, etc. - More login options like face id - More availability for the Focustronic Mastertronic automatic water tester / or an "in house option" or something. Only thing missing to really be able to be #1 in this space is this. (understand this is not fully in coralvues control at the moment, but feedback they need to hear to really be competitive) ### 2/5 — Flaw that could potentially destroy your tank *2022-01-09, version 2.2.0* The app is easy fairly easy to set up and use. However, I learned today that it randomly logs you out of your account, which was almost a disaster for me. I had moved some rockwork quickly out of my tank to capture and remove a fish. This lowered the water level and my ATO kicked on. Realizing my mistake, I went to turn off the ATO in the app, only to find that I had been logged out. I didn’t remember my password because I had only entered it once back when I set up my account and there was no way to sign in with facial recognition, so in order to turn off my ATO I had to unscrew and unplug it from the controller unit. Luckily the plug was in a place that was easy to get to and my salinity only dropped by 0.005 SG. I would not trust this app/controller if I had valuable corals in my tank until they fix this login problem. Either keep me logged in, or allow users to log in with Face ID. ### 4/5 — Good, but definitely needs work *2021-09-01, version 2.0.14* The app is decent, interface is mostly easy to navigate but there are some bugs. Reordering graphs seems to reset itself every time I open the app. I’m either doing it wrong or there is a bug. ### 2/5 — Does not work *2021-08-03, version 2.0.14* Worked for couple days now will not allow me to control flow output. ### 2/5 — Tonns of bugs *2021-06-05, version 2.0.13* I've ysed the app for just 1 day and found at least 3 bugs while trying to create a custom feeding mode. The app is a disaster. Tech support is very responsive though. How did they manage to get 3.8 stars in AppStore? Thirty four (34!) 5-star reviews on Oct 1st - that's impressive! ### 3/5 — Works well but no notifications?! *2021-01-28, version 2.0.11* Works great for me but there’s no option for international phone numbers and even worse, no app notifications. That’s right - the app can’t send notifications to your phone. What? ### 2/5 — Mala *2021-01-09, version 2.0.11* A cada rato de borra la configuración ## Most critical reviews (10 lowest-rated) ### 1/5 — What is wrong with this? *2025-11-02, version 3.3.1* Everytime I try to run a dual setup of these power heads it never connects anymore, they run at different speeds even when at the same speed…. The app constantly has glitches and bugs and I can’t even connect to my account/wifi with this anymore :( very disappointed ### 1/5 — Hardware and software garbage *2025-10-21, version 3.3.1* These are horrendous to set up. And the wifi connectivity range is terrible with these devices as well. Returning the junk as well as deleting this app. ### 1/5 — Buy Neptune Instead *2025-07-26, version 3.3.0* I have had this system and this app for three years. All I have to say to justify my one star is that I wish I had bought Neptune instead. ### 1/5 — Absolute garbage! *2023-06-29, version 2.6.0* Interface is trash, support for this company is trash, paid $300 for a icecap gyro 2k a few years ago and it worked great. Now it says I need to update firmware for it to work but has no update to select. So now I’m stuck with a fully inoperable pump and a controller that has no software. I’m unable to use a previous version of firmware because the app and desktop version won’t let me select a device to make any changes to unless I update it, and am unable to update it without selecting a device. So I’m stuck in a catch 22 and a useless $300 controller and pump. Would give less than 1 star if I was able to. ### 1/5 — Horrible App *2023-02-14, version 2.6.0* Wave makers should not claim to be WiFi, they are not. I will try to return the IceCap because of false advertising. Don’t buy an icecap hydros control er. Their app team keeps spitting out what they call updates but just makes them worse. Every update causes a new problem. Their developers are horrible. ### 1/5 — Literally awful *2023-01-25, version 2.5.0* So awful. Awful pump, awful app. I’ve had the pump for MONTHS and it never worked with the app. I decided to try once again today to try and link it by resetting the app to factory settings - and the whole pump died. It stopped working & I could not get it to start up again for the LIFE of me. Almost destroyed my whole tank & i’m so happy I had a backup powerhead. App interface is confusing and uses jargon i’ve never heard before. Awful. Straight into the trash. ### 1/5 — Pesima *2022-03-12, version 2.3.1* Falla demaciado solo dice error ### 1/5 — Regret buying *2022-02-03, version 2.3.0* Can t get app to show same page as I tube video no way to actually get it to work as pump never shows up as an option ### 1/5 — Junk app *2021-09-16, version 2.0.14* Useless app won’t connect don’t buy these pumps if you did return them ASAP. ### 1/5 — Terrible interface *2021-06-26, version 2.0.14* you HAVE to create an account AND apply a password to that account just to use the app. I’m not sure how many people have a problem with neighbors hacking their power heads through their routers but apparently it’s a big problem somewhere…never heard of it myself. At first, the interface was difficult and non-compliant. It automatically setup my 2k as a 4K. So even if I did set it to 20% power, the 2k is still at 100%…which is likely what killed my pink tip torch because it took me 2 DAYS to figure out why the power wouldn’t adjust even though I was changing the settings, thanks for that. When I switched phones, the app is now in “read only mode” I will probably spend a week trying to figure that crap out. BEFORE YOU USE THIS PRODUCT…ask yourself if you want to deal with the headache of trying to figure out what’s wrong with this app every other week. The power head is AWESOME…if the app can work right. ## Most praised reviews (10 highest-rated) ### 5/5 — Way better than Neptune *2025-09-19, version 3.3.1* This is hands down the best controller on the market I have 6 devices linked up in a collective flawless ### 5/5 — Super Easy and Intuitive! *2022-06-07, version 2.3.2* Being a first time controller user I couldn’t have gone with a better choice than the hydros. The app is easy to understand and use, and regardless of your expertise in controllers, you’ll be up and running from day one. Nice job!! ### 5/5 — Buena *2022-01-09, version 2.2.0* Excelente app tiene algunos errores pero se soluciona rápido. ### 5/5 — Love it *2021-11-24, version 2.2.0* Love the app, just got the hydros 4 and it works perfectly for me, good so far. Never had a controller before but it was easy to set up. ### 5/5 — Hydros control *2021-11-07, version 2.2.0* Even better with the new update I feel very good knowing I live home and my tank is operating and it will alert me if anything goes wrong ### 5/5 — Amazing app for amazing aquarium controller *2021-11-07, version 2.2.0* From day one of using Hydros, been using it almost a year, the app has been fantastic. Never freezes, never fails to load, works and functions as it should. With every update the app and controller has increased functionality. I love it! ### 5/5 — One minor issue identified *2020-11-14, version 2.0.10* This app works great. Very easy to use and quite intuitive. Only issue I’ve identified is that you can only view 4 modes at a time. The software needs a minor update to correct this. I’ve created a mode to individually turn off filters which are each on their own UPS. So having one mode to keep all other filters on while turning one off is really handy. Seems like a missing display requirement. The app should not limit the # of modes to be displayed as a button to only 4. All created modes are displayed in the drop down text list. Please update as soon as possible. Thanks! Love this product! It’s fantastic. I have 3 tanks controlled with a controller 2. Super happy. ### 5/5 — Great update! *2020-10-09, version 2.0.7* I love the update. Great layout and very easy to navigate settings. Selecting a pump icon opens up instant control and advanced settings, which makes adjustments super easy. Light and dark themes are awesome too. ### 5/5 — Works great!! *2020-10-01, version 1.0.13* Works great for me!! ### 5/5 — Seems simple and easy to use *2020-10-01, version 1.0.13* Awesome --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
