Hello! So very new to the salt water world. My husband and i have had our tank set up for a few months (or more)... When we were finally ready to start about a month ago we did a cycle and my husband turned the lights on... Big mistake. Way too much algae growth!! The guy at our local fish store suggested to turn all the lights off and start doing 20% water changes every one to two days until we hit 100% and then switch to 10% until our levels were back to normal. I also covered the tank in cardboard to keep the light out Took about a week and a half and we finally got our first fish yesterday! Two DaVinci Clownfish, a couple sea urchins, a pyramid snail, two spiny astrea snails and three ring cowrie snails. So far everyone seems happy! I'm loving the urchins, they've just buddied right up and move along our rocks together, pretty cute!! Anyone else noticed urchins stick together like that?
