Hey all, I have a question regarding filtration for my 20gal high tank... I'm using this sponge filter rated for up to 20gal powered by this Tetra Whisper air pump rated for 20-40 gallons. I chose sponge because I'm using a sand substrate, and I wanted to protect shrimp babies. The tank has live plants.
My tank is stocked with 2 honey gourami, 1 nerite snail, 4 neon tetras (I originally had 11, but got a bad batch), and 6 cherry shrimp (some are berried). AqAdvisor rates me at 153% filtration right now, but I want to add habrosus corydora and some more tetras in the future and I'm learning I'm supposed to have way more filtration than what's rated for 20gals?
How do I make sure the filtration is adequate? AqAdvisor rates filtration capacity at 79% with my stock plan. Can I just split the airline tube with a valve and add another 20gal sponge? Or should I add an HOB filter instead -- and what would work best with sand substrate? (concerned about sand wrecking the impeller)
