I want me water even cleaner, any suggestion. Pictures inside!
and see my posts 24 & 40 well as other posts in that thread. Good luck to you.
I agree. For a 20 gallon, a canister filter is unnecessary. If you do get one, get an Eheim 2213. Still, totally unnecessary. I'd suggest running an Aquaclear 70 with the flow turned down to minimum on a 20G tank.
Run a pair of foam blocks and a bag of biomedia. Cut a poly filter sheet to fit the filter and put it between the foam and the biomedia and it'll polish your water. Use a prefilter sponge on the intake. It's all you need.
Canisters don't really become necessary or practical until you get into the 50 gallon ballpark.
Having said all that, do you really need to change anything? No. It looks like you have a decent sized HOB
and a hydrosponge filter both running in there. You don't appear to have a terribly high bio-load. Why change anything?
BTW if you want your snail to have a perfect shell and explosive growth rate, feed it this
It's skim milk based. Best thing you could ever feed your snails. They need a lot of food. Give it a balanced diet with algae wafers, some frozen food, and this stuff.
