Pull the feeding back to one cube per day. Also, when you defrost the cubes, skim them out and don't put the water you defrosted it in back into the tank.
All that said, 20 or 30 is nothing to stress about IMO... just keep an eye on it and make sure it doesn't keep going up.
BTW, what brand of test kit are you using? |
