No longer works on my iPad Mini 2

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.

We are bummed to hear of your disappointment, but a possible solution is to use our web application through your internet browser. The HYDROS web application offers the same functionality as the app, and you can access it directly at CoralVueHYDROS.com.

Flaw that could potentially destroy your tank

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.

Sorry to hear about your troubles. Remembering passwords can be tricky, especially when dealing with an urgent matter. The great thing about HYDROS is that you can set up rules to help prevent situations like this. If you would like to learn more, please get in touch with our HYDROS Experts at support@coralvue.com.

Terrible interface

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.
