Chaeto in 2nd chamber
Chaeto in 2nd chamber
Heads up to everyone, I had some chaeto in the back 2nd chamber with a light velcroed to the back of the tank. Pieces kept clogging both my overflow sponge and my return pump. So I decided it wasn't worth the pain and was going to take it out. So last night, I opened the 2nd chamber (had to remove my Vortech box) and put my hand down there, NO CHAETO! I looked further and realized what happened.
There was massive coralline algae buildup on the back glass right where my light was shining in, blocking the light from getting to the chaeto. Therefore, the chaeto died slowly and the little pieces ended up in the display, bigger pieces ended up stuck to the pump.
So, unless you want to scrape the back of the tank, be careful adding a light back there. I have no interest in scraping it, so I'll just not add any more chaeto. Wondering if I should keep the light on though, does coralline provide any sort of nutrient export? My wife likes the light back there as a nightlight (tank is in the kitchen) if she needs to go in there. Any thoughts?
