Just joined the group & trying to learn the basics of cycling, we started a month ago, waited a week before adding fish. We had no live plants at the time, we now have 4. We have 24 fish, 4 mollies, 3 Danios (zebra), 4 asst guppies, 6 neon tetras, 1 Kuhli Loach, 3 Platies, 3 Glo fish, 4 snails. We did not add all these fish at 1 time, over the last 3 wks. I think we have too many fish for a 29 gal, although we have been told we should be fine. We have a 40 gal filter, not a canister, it hangs on the back. We have 2 bubble stones. We just did an ammonia check, by strips & an ammonia tester suction cupped to sidewall, both said stressful. I added ammonia tablets to see if this will change it. We do a weekly water change of about 4 gal. Basically, we need to know, is the approx 4 gal weekly change good? ANY tips will be appreciated!
