Hi, I bought a 70gallon hang back filter the AquaClear for my 20 gallon tank and it camer with filter inserts. I was wondering if these are safe for saltwater? I have 2 months of fresh water experience and have used these but im not sure if these are safe. If not or if anything, what do i put in my filter?
ps. im not going to use a sump or a canister YET. so i just need help with my hang back filter. THANK YOU!
here are the filter inserts
