There's something not quite right about your tank. A fully cycled tank
shouldn't show any ammonia or nitrites. Your plants should also keep those
things down, as well as the end-product, nitrates.

So I suggest you get some test kits and find out what's going on.

Also, I recommend rethinking your mix of fish. You can avoid a lot of
problems with goldfish when you keep them at temperatures below 75F and in
base pH (not that you can't keep them at all warmer). Goldfish also tend to
be clumsy swimmers and to sleep at night when many algae eaters are most
active. So there is a risk involved even if you've been lucky so far.
