Guys,

I'm thinking of doing undergravel for the next tank im setting up. Gonna be 15 gallons. My concern is too much suction which shortens the life of the substrate. I want a good 2-3 years before having to redo the whole tank entirely instead of just a year like I have read. If longer, even better!

DIY hooking up to a canister for me seems too strong and unnecessary. Powerhead, still a bit too much right?

Whats left would be a HOB or Airstone. Anyone have any experience with these that could give suggestions or recommedations?

Soil would be ADA Aquasoil btw.

Curious why old school under gravel.

Because they work great in shrimp tanks.

I think an airstone would provide gentle, yet effective circulation.

They clog so easily. I'd expect air stone power to be inadequate quickly. Especially as roots begin to penetrate the UG. Can't beat a canister (or sump) for tuning flow.

How large is the tank?

I run UGF + some version of sponge filter (dual sponge or hmf) in all my tanks.

UGF are great filters for shrimp only tanks.


also 2-3 years with aquasoil isnt the best idea, its possible under ideal conditions but requires you really watching your parameters as you clock over a year.
