Iv went through about 10 pages reading post after post. Which now has added more ?'s. This is what i have 29gal with about 1" of the cheap sand from lfs, 1 ac 402 power head, and a small hob filter wich will be removed later. Im going to get a little bit of lr and i suppose a bit more sand. Il add a skimmer and remove the hob filter. I want to put a crab, snail and few different fish in. So with this info should what should i add or change like ls on top of sand i have or just more sand? Filtration ok? I see alot of talk about lighting all i have is the standard bulb that is comes with this ok? This tank is just to see if i like it this was my starter tank when i got into cichlids and now i want to see if like sw if i do then bigger tank will come.
