Clean up crew was a waste of money. Had about 80 snails and half were DOA and only about 20 are left. The bigger ones basically stay on the glass and do nothing. Ever now and then ill see one on the rocks. Scrubbed the rocks in the water change water last weekend and only run my light about four hours a day and I can already see the red coming back. Ordering new ATI bulbs next week and going to get a hermit crab pack from reefs2go. The crabs seem to do more than the snails do. Also am going to get a test kit for Cal, Alk and Mag. Want to try some corals again. The one time I put some corals in it didn't go so well. I'm using Coralife T5 bulbs. Corals never opened at all. Couldnt test the big three because I didn't have any test kits for those. But was told there wasn't anything in the tank to use those up so shouldn't need to test it yet. See all these new tanks with corals and mine is 6 months in so hopefully I can get some going soon. Also thinking of getting another power head for more flow. But right now the two I have moves sand around and they are not pointing down very far. Where would be a good place to put the third power head.
