Are to small feeders enough to drive a new tanks ammonia up to the 4-5 ppm area.....i started up a 55 gallon tank for goldies and it has two filters rated at like 60 gallons a piece on it...and i did put a filter from a well established tank and a piece of rock in it......i did a 50 percent w/c yesterday and im going to do anouther today to get the ammonia down even further
