ok i have my 10 gallon tank set up and ready to begin, i have put in the black sand, have 1 powerhead, and one hob filter, i have not added the sw yet because i havent been able to get to the lfs since i have returned from vacation, so what do i do next? lol i know i will need a hydrometer, another powerhead, and i was thinking of just doing lr in the hob filter, if that can even work. so any advice for my first ever sw setup? and there is no plan on stocking yet besides possibly a few snails or a hermit.
