The damsils were to cycle. And yes a very big mistake. The tank was full of affricans and the LPS owner is a real good friend. I gave him the affricans, he have me the live CC and live rockand 8 damcils out of a tank that was already set up and running. I dont know how but I never had over .25 amo and the nitrites and nitrates never got out of the safe range. He also has a tank cleaning business and gave me a bundle of little critters from some of the Dr's and Lawyer's tanks. It has been up and going about 12 weeks.
