gravel...big mistake????

[HotSauce]

im new to this hobby and when i got all my equipments i bought a couple of bags of regular gravel, the same ones used for Freshwater tanks...cheap $4/bag...my tank has been running for almost a month now with the gravel...now after much reading found out that saltwter tanks need aragonite/ live sand!! currently have 3 damsels...will they be ok? if yes, can i keep the gravel and add some inverts down the road?? or should i take the whole thing out and replace with sand??? need help ASAP..

definitely take that gravel out and get u some sand!!! Go with some aragonite, and i'd shoot for around 3-4". i'm soon gonna replace my cc and sand mix with just an aragonite dsb
