I'm running a small HOB
fuge, about 5 gallons, with chaeto. My tank is 110 gallons and I realize the HOB
is probably undersized as a fuge for my set-up. I trimmed the chaeto back yesterday and put two seperate golf ball sized pieces partially held down by rocks on my sandbed. It seems to be staying together - not really in direct water flow. The tang seems to love it - I'm looking to decrease my PO4
and keep my NO3
low, so I'm assuming the more chaeto the better.
1. Does anyone keep chaeto in their main tank?
2. If chaeto dies, will it leach PO4
back into the water?
3. Is it nutritional for tangs, or just a treat?
