Please update the pro version. 

Brilliant!! I see you have updated this version but I paid for the pro version so can you please update that too. Very handy for logging test results and calculating dosage all in the same app👍👍👍

Thank you 😀

### 4/5 — Red sea!!!!

*2014-10-15, version 2.0*

Pas mal dommage que le test kh ne soit pas en liquide
Très bien pour calculer la dose de CA et MG manquante dans mon aqua

### 1/5 — Avoid

*2012-10-21, version 1.61*

Worked once for calculating alk for soda ash, now simply crashes when attempting the same

### 4/5 — Perfect

*2012-07-19, version 1.61*

Great app but needs red sea products added.

### 4/5 — Useful app

*2012-01-21, version 1.5*

It takes the headache out of working out the amount of additives needed. It could do with a few more manufacturers on i.e. Red Sea Reef Care programme.

### 3/5 — En français

*2011-10-10, version 1.5*

Serrais super en français merci

### 5/5 — Stunningly useful app for reefers

*2011-04-27, version 1.5*

Absolutely love this!
Request! : salifert products! Particularly for the Kh buffer, spins my mind trying to work out dosage for buffering RO top up water! Another thing to think about would be salt brands to SG ie: red sea pro x cups for x gallons at x temp, this isnt a complaint coz this app is awesome, just a suggestion!
