I really like the non co2 enrichment method, which I want to use on with my 20 gallon. The thing is I only plan on keeping 2 dwarf puffers in the tank. Curious as to what people think about this fish load working on my tank. Id like as much plant mass as possible. 2wpg over the tank. Thanks

If you keep very slow growing plants, or a rich substrate with mainly rooting plants, it might work. Fast growing plants will deplete the nutrients significantly faster. Worst comes to worse, you might need to fertilize once in a while.

Forgot to mention I plan to dose KNO3 and PO4, as well as seachem eq every week or two as per Tom's recommendations.

If you're dosing anyway, there's no need for a high fish load. In fact you'll be better off with a lower fish load, it cuts down on algae potential. Choose low light plants and you'll be set. Dwarf puffers are awesome. Unfortunately they don't jive with my water type.

Thank you very much for the help.
