Problems with new Kessil 350

[kingpin9995]

I had over my 52 corner bowfront reef two Kessil A150's which were working great in regards to growth etc. I decided to purchase the A350 and sell the 150's. Since the switch about 2 months ago things have gone down hill. I have a breakout of hair algae, my zoa's have shrunk up, mushrooms have shrunk, and my frogspawn has started to not look so great after great growth under the two 150's. My paramaters are great and no sign of high nitrates, ammonia. Could this light have something to do with it. I did slowly raise the intensity of the 350. Love the light but not so much the effects in the last few months.

I did wonder about my rodi. My reading is 0.120 and I have had it about a year and have not changed cartridges as I don't make a ton of water except for water changes which I do weekly about 5 gallons.

Any suggestions or if others have had any problems with the 350 would be appreciated.

I know this thread is a little old, however I thought Id post in case you hadn't figured anything out.

It seems the new light is coincidental to me. I would be looking at the source water. Definitely sounds like a build up of something that is both feeding the algae and harming the corals. A new light in and of itself should not have this effect.

Lights are strong (more than you think) I moved both 350W up 18" above the water. Corals are doing great now. AT first the lights was about 8" above water and the corals seam to go down hill. (Shrinking and getting pale).
