I used to grow chaeto well. I had a cheap Chinese plant grow light I bought from Amazon as a temporary thing and it grew like wildfire. However, I noticed that there was some rust on it after a while which made me uncomfortable so I decided to buy a purpose built light. I bought a Kessil H80 about 6 months ago and ever since, I haven't been able to grow Chaeto. I've tried the settings on grow, on bloom at 100%, 50% and 30% intensity. Nothing. It just dies slowly and pumps tons of phosphates and nitrate into my tank as it dies. This results in algae blooms in my DT or me having to spend a fortune on salt from the frequent water changes just to keep up. It doesn't float, it just sinks to the bottom of the fuge (it used to float when it was growing healthfully). It is definitely the light because this all started just weeks after I set it up. And I know people have success with it, I'm just at a complete loss and I'm SO frustrated. It is messing with everything because they dying chaeto is doing the exact opposite of what it should be doing.
