So, I've had my 20gal for 3 months and decided to upgrade to a 75gal (LFS sold me fish that will get too big and this gave me an excuse to get a bigger tank )
I bought a 75gal acrylic tank on craigslist and it came with a CPR Cyclone Bak-pak 2R filter. So I am going to betray my ignorance here and ask whether I can still use this for freshwater and if so do I need to supplement with another filter?
I also have a more specific question, if proteins skimmers actually remove harmful organic comps and lighten the bioload why don't we just use those for freshwater too? Is it not worth it cost-wise? overkill maybe?
Thanks,
