Hi all,
I've been lurking for the past 8 months, but this is my first post seeking help. Last weekend I got a nice sized tort colony from a friend who has had it stable in his tank for the past 2+ years. In his tank it was in a rack about 75% up the glass. We believe it was getting a lot of par in this config, but don't have par readings to confirm.
In my tank, I have a kessil a360x and aqualife 4xt5 retrofit over a 30x30x24 92g cube. The top of the structure is about 6" from the surface and the light is about 8" above the water surface. According to brs videos on the light setup, I should have a hot spot under the kessil north of 450 par.
I placed it pretty high up on the middle of the tank so it's likely near that hot spot. After a few days I started to notice the corallites on the acropora turning white. It's more pronounced with the lights off. Tips don't looks bad so I'm confused as to what might be causing this.
Parameters are:
Ph 8.3
Salinity 1.0245
Alk 7.4-7.6
Ammo/nitrate: 0.0
Nitrite: 0.03 (Hannah uln tester)
Mag: 1260
Ive relocated the colony to a rack in hopes it might be too much light. Anything else I should consider looking into? Any dips to keep it from dying, etc?
Thanks for the assistance.
