anybody with a established sand bed want to part with a cup of sand? i would like to add it to my tank for a little diversity. also anyone here in the qc have a extra magnesium test kit they want to part with? ive tried everywhere to locate one and dont want to pay shipping for just a test kit but will if i have too i guess. i called AE yesterday or saturday and he said he doesnt test for it, i told him why i need one, it ended up with me telling him to read the reef chemistry forum on reef central. but he did try and sell me some sort of crap thats really good for growing carraline, 32 bucks a bottle.
