Water flow or pump rate?

Oxygenation?

Solids or water clarity?

Electrical ground fault or shock protection?

At first glance, your ammonia is really high, I would slow down on the feeding and maybe do a bit of a water change out.

Ya we recently have had no Ammonia and just started feeding 2x per day, so we have stopped that. Will try out a 1/3 water change :) Thanks
