So I have a small tank atm with a lot of tangs. Had a heck of a time list fish after fish spent top$$$ on everything but unfortunately until recently I have finally been able to have a stable community of 2 blue tang, I quite big sail fin tang, one brown tang, one yellow tang, one sand shifter , one banana wrass, and 5 blue chromis. Free of any disease battled white spot for months and lost quite a huge amount of fish. Now that I have finally got a stable colony am upgrading to a big 800 litres tank already purchase just need to plumb and build a sump. Am planning putting 2 sump with regugium, live rocks, 2 skimmer and 2 reactors. Any suggestions will be most welcome. I will after cycling the big tank transfer my fish to it and use the smaller one for any new fish for quarantine until I have what I want and get rid of it. Please help needed to make sure am doing everything right. Thanks
