Hello I'm new to this forum and I would like some advice on setting up my aquarium. I have a 37 gallon tall aquarium. To filter it I have an undergravel filter with 2 aquatic gardens 600 powerheads attached to the uplift tubes. I also have a marineland penguin 350 bio-wheel power filter good for 75 gallons. Is this too much? I"ve heard nothing but bad things about undergravel filters but I think it would be too much of a pain to remove it now. I would like to have this a well planted aquarium and what plants grow well with an UGF? I've had the tank set up for 2 days and I am using Hagen Nutrafin cycler along with 2 lyretail sailfin mollies and some snails to cycle it. So far I haven't read any ammonia, nitrite, or nitrate levels. Is it safe to add more fish since I'm using Cycle?
