spoke to @FutureInterest earlier about switching over from my current 20 gal to the 40 i picked up today and he gave me some advice but also told me to post here to get more advice from everyone so my question is what do i need or what would be the best way to transfer everything over? my 20 has been running since march first and currently houses a pair of clowns and a goby along with some coral,i will be buying new sand and some more rock
