What Is Old Tank Syndrome?

    I have had my 10 gallon betta tank for almost a year and will be setting up an old 55 gallon tank in the fall. I do water changes on my betta tank once or twice a week at 30-40%. I plan on at least that for the 55.

    What exactly is "Old tank syndrome" and is there a way to prevent it from happening besides buying a brand new tank?

    Do frequent, large water changes. Usually, it is because of nitrates building up over time

    I do the maximum I can on my betta tank due to heater placement. I am gonna maybe trying putting my 55 gallon heaters horizontal? So I can do bigger water changes. Do you think with the water changes I am doing on my 10 gallon Frazier will be ok for a while? Nitrates haven't ever been above 40 while cycling and 20 since I put him in last October.

    30-40% is perfectly fine. Usually occurs with those who change less water

    Ok. Good to know! :). I'll aim for the same amount for my 55 gallon at least.
