I dont really think it matters how many CORALS you put in but it will depend what type of corals as in Leathers, Shrooms, Zoanthids, LPS's or SPS's when it comes to your lighting and you wont be able to put an Anemone in there because they will get to large for a 10 gallon. I feel you should get all your basic test kits, Ammonia, Trites, Trates and PH and with Corals you should also get Alk, Calcium and Mag and you will need a way to check your SG and I would suggest a refractometer. I would scratch the whisper filter and just go with a couple PH's, good flow with sand and LR will be your filter and then 10-20% WC every week and you should be fine
I can't afford it
