hi, i am going to be converting my freshwater tank into a salt water tank. its a 55 gal
with a filters, a aqaue clear hang on, and whisper bio bag hang on. i went to my LFS
today and asked the lady there wat i need to do to start out, she said i should buy instand ocean, and some live rocks and then let it sit for 24 hours, then she said to put some damsels in, but i think ill just do the raw shrimp thing. anyways can instant ocean just go right into my tank now? or does it need to be mixed in a bucket or something? and also wat kinda of gravel is good?
