I would prefer a remote of some sort, the Bluetooth on my end took a long time to connect ### 1/5 — Horrible Programmers *2026-05-31, version 1.0.9* Crashes constantly ### 3/5 — Remote Access is Necessary *2026-05-27, version 1.0.9* This app works fine for me and gives me the control I need over both my Marine 3.0 and Reef 4.0. - while I’m at home. But since it has no internal clock, it doesn’t know what to do when the power returns after an outage. So it really needs to provide remote access. One way to do this is an internal computer. Another would be to make it Möbius or Apex MXM aware. But please do something , because even a momentary outage makes the Fluval lamp a boat anchor. ### 1/5 — Poorly Made *2026-05-19, version 1.0.8* Crashes often, lots of bugs, and many features that were just never thought through but advertised as complete. I might even call this a scam. ### 1/5 — Terrible app. Everyone at Hagen should be euthanized. *2026-05-17, version 1.0.8* They will not fix anything, and it’s been years with dozens of glaring bugs. The light will randomly lose connection, switch to Bluetooth instead of wifi, shut off, settings get wiped etc etc etc. there are literally more broken features than functional ones. And to top it off, the light is designed so that when settings are changed/modes are switched, the light goes to max brightness and flashes on and off three times which is….. great for the stress of livestock. Did homo ergaster design the software for this thing? What is going on in Germany? ### 1/5 — Good product, horrible app *2026-05-17, version 1.0.8* Connected once, then failed to connect after a couple of launches. Went through the process of uninstalling and reinstalling only to have it not connect. If you purchased this product, return it for one with a better app, it’s 2026, come on. ### 1/5 — Unstable Connection *2026-05-10, version 1.0.8* Expensive freaking light for it to not stay connected. Can’t update the app either, trying to set up a 60 gallon with a junk light. ### 2/5 — Horrible layout compared to previous app. *2026-04-01, version 1.0.8* Much prefer the other app. But unfortunately, the reef 4.0 requires this app. ### 1/5 — Ai 2026 - Fix the App *2026-03-11, version 1.0.8* Ai in 2026 is good enough that you guys could fix the features overnight. What is goin on???? This app does not match the quality of the light. Competition will take over of you don’t fix this thing ASAP, one night of work! ### 1/5 — App does not work and now light stopped working *2026-03-10, version 1.0.8* I just bought the reef 4.0 today Mar 9, 2026 got it home worked great really like it then downloaded the app for the ability to create a schedule and the app crashes and won’t config and also shut down my light to the point we can’t turn it on any more just sits and a green power light. ## Frequently asked questions about FluvalConnect ### What does the FluvalConnect app do?
