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.

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.
