[AquaticLife] Replacing internal filter
An airline powered UGF isn’t the best thing so you should still run the powerhead from time to time so it will suck the detritus through the UGF better but the airline powered UGF will at least keep fresh water flowing over the gravel and filter media at all times to keep the N-bacteria alive and it will also help with the biological filtration that is needed for your overstocked tank. Running both the UGF with the airline power and the internal filter 24/7 will keep the water much better for your fish. Then maybe a couple of times a day, you can turn on the powerhead to really suck the detritus down through the gravel and UGF.
