Hi all, One week ago I used most of a bottle of TSS rated for 200 gallons in my 20 gallon. I then added three honey gourami. One week later: Temp 76.5 PH 7.2~ Ammonia: 4, possibly even 8 (hard to read) Nitrite and nitrate: 0 My fish haven't eaten in the week they've been home. Just to make sure I'm doing the right thing, I'm going to do a huge water change (maybe 3 5 gallon buckets but not at once), test for ammonia, and when it's below 1ppm wait 24 hours and use more TSS (bought from a different store). Is this my best plan right now?
