I have read the Q&A on TSS, I ended up with bladder snail eggs and freaked out. I took everything out scrubbed it and well now I'm in a full blown cycle. Anyway to my question's. Does the ammonia have to be at 0 before I add TSS, also idoes Ph nitrates nitrites has to be at 0 before adding TSS? I was also wondering about my HOB since I'm doing a full cycle I figured it would be easier to add ceramic media to my HOB, but wasn't sure if it would be benificial or easier for the BB to take hold during this cycle. Thank you so much.
