alright, ive kept saltwater and freshwater tanks. i would like to do a brackish setup with scats and monos. maybe some archers or puffers. what size tank should i consider doing. i found a 75 with dual overflo (over kill on a 75 IMO) and stand for like 300! what do the profesionals think about this? i have a few options i can transfer my 65 saltwater in the 75 because of the filtration and use a sump instead and keep the canister on the 65!! sound good. let me know. thanks a bunch!!
