The manufacturer's reccomended height for the Hydra 32 is 8 -10" above the waterline. The picture and my old eyes make it difficult to see if there is coral in your tank. If there is, I would move them down slowly so that you don't shock anything and adjust the intensity accordingly.Hello, I have two ai hydra 32’s and I’m running a mixed reef. My tank is a 36x24x24 I am wondering what level I should set my lights at. I am going to rent a par meter but until then where should I be sitting.
They are mounted exactly 14 inches above the water line. This was tested to be the most even spread of light for the hydra 32 by brs. I do have corals I have one Acan and another sps can’t remember the name and have created a collection of lps and zoas. I had them at 30% as to not burn anyone since I haven’t had a par meter. Considering everyone has said 60-75% I have moved them to 50% for tomorrow I will rent a par meter soon
You seem to have a ton of light spillage though. Did brs have the exact same tank as yours? Other wise I would lower them. Your tank seems pretty tall and the rock is pretty down low I don’t think you will have an issue if you lower them. I keep my lights 8” above the surface for the purpose of minimizing light spillage and having the light blasting my eyes because I personally find it quite annoying
