i set up a tank and let it cycle for a month before i put in live rock and let it sit for another month. after about two weeks there was what seemed to be algae growing on the rock which eventually spread to the sand, so i got snails which cleared up the algae pretty much overnight. today i bought what i was told was a purple tipped anemone and after aclimating it i placed it in the tank. the anemone was open and inflated the whole time and hasn't really moved around but appears to be where he wants to be. at the moment i have no fish in the tank but i am waiting on a mated pair of clownfish. i am getting new lighting next week with moonlight led and florescent bulbs. it is a 30 gallon and i have a 70 gallon biowheel filter and a 30 gallon power head as well as a 70 gallon powerhead( which i took out when i put the anemone in because it was just getting tossed around by it should i buy a different lighting system or keep with my original decision to buy the florescent bulbs with moonlight leds? is it ok to feed the anemone or should i wait a few day to make sure he is doing ok? do i need to add calcium to my tank ?(my calcium is currently at 420) any advice would be helpful since i am so new to the saltwater thanks!!!!
