Thanks Shawna., 7 of the 8 tanks are linked together at the sump in the basement. So it's really one big system plus a 65 gallon that runs on a canister filter. Top off is automated via a still reservoir(32 gallon brute can) of klakwasser which I refill every 5 days or so. Much of it runs on gravity from tank to tank to sup to crlyptic zone to rsdb to refugia. I keep another 32 g brute with a float valve that refills with ro automatically . I also keep a 16 gallon bin of mixed salt water going. It's not very hard . There are a few things more I could automate but like to keep my hands in it. My son does a nice job watching it for me when I'm not here. If not my grandson's dad stops by. Not much to do except feed , dose vodka vinegar and keep track of the kalk reservoir. unless something breaks.
