This is was the first tank I ever put together. I honestly went to my local fish store and got all the info from them before doing much research which I’m wrong for lol. My lfs told me to buy dr Tim’s one and only use live sand and 10 pounds of live rock and a fish and he said to check my levels after 3 days. I did what he told me to do my nitrites and ammonia were at 0. He told me I was cycled and reccomended me to buy 4 snails and A gsp and frogspawn. 3 weeks in the gsp hasn’t opened in a week and half and started to open today randomly. and my nitrites and nitrates are sky high should I do a water change or take out the corals and snails.
