I moved my fish from 1 tank to a larger tank, everything out of the old tank went into new tank. The 1st day my ammonia went up to 0.25, yesterday 0.5, I did a 30% water change today, tested again and it's still 0.5! I've got some prime, some amquel plus and some stress zyme here, I don't really like using chemicals but will any of these be worth using? At the moment I've been using Nutrafin Aqua Plus Dechlorinator to treat the tap water. My peppermint pleco isn't looking to good and my L134's are a little pale :cry:.
