It really is better to rule it out. A simple test will yell you. Once you verify it isn't the source water it'll be safe to continue water changes. Where are you getting your water? I agree, overfeeding is the big culprit here but water changes should be making a difference by now. I'd skip feeding for a full two days and only feed 1/5th or less of what you were feeding before. Right now the ammonia is the threat to everybody's health. Many many people only feed every three days so you're NOT going to be harming your fish by doing this. You have to protect them from the ammonia, nitrite and nitrate. That's job one. It starts with testing your new water.
ok ill run an ammonia test on the water, do another water change today, and i havent fed them in 2 days also.
also i noticed one of my rocks has been turning a bright gold? is this algae, i have been leaving the lights on for 10-12 hours a day, i also have new lights coming that are t5h0
im also going to try to raise my salinity from 1.022 to 1.023-1.024 this week. I have been waiting 2 weeks to add a goby but i dont feel safe right now with all my tank fluctuations, goby are not hardy are they? the yellow watchman is the one i want
Ok well dats a natural diatom bloom give ur tank time it will go away in time as ur tank matures a lot of us been thru that in our beginnings but keep ur phosphates down and limit ur lights to da lowest amount of light time possible ull be fine and never over feed
