OK, heres the deal- I have two tanks; a 125g with a 60g sump that I want to set up as a fish only, and a 75g with a 55g sump that I want as a reef tank. The 75g has been my freshwater tank for several years, and it bores me now. The 55g sump tank has been my current start of a reef tank, just going through cycling and algea growths now with a few damsels in it. I got about 50lbs of dead live rock from a friend of mine (all white- nothing growing on it) and put it in my tank with about another 15lbs of cured live rock from my LFS. When I bought the cured rock I was given the impression that the coraline algea would spread very quickly. 5 months later and still no coraline. I've been dosing with B-Ionic daily and topping off with kalkwasser every other time for about a month.

That all being said, I guess it's time to get to my questions. I'm going to start over with the reef tank transferring everything to the 75g, would it help the rock to cure if I put it in the sump of the 125g to try to get the most water movement in the least amount of space? Is the length of time for it to cure supposed to be this long? I know nothing good happens fast in a reef tank, but is 5 months normal? Other than the B-Ionic and kalkwasser is there anything I can do to encourage growth? Also, it appears as though 40% of the algea sluffed off the cured live rock I bought and is just recently beggining to come back- it looks like very thin layers have been placed on the edge of the good growth, with the edges peeled up (I don't know if this makes any sense, will have to borrow my dads digital camera to try to post a picture if it doesnt).

Sorry for the lengthy post, but I would appreciate any help you guys can give me. Thanks,

Scott

Calcium, alkalinity and lighting are the keys to coraline algea growth. Bionic should take care of the CA and Alk. What type of lighting do you have?

What is your CA and Alk levels? Do you have a good test kit?

I'm using a SeaChem test kit right now, my calcium is high, about 550 mg/liter. I've read 440 is closer to what you want, but I was trying to encourage growth. I don't have an alkalinity test kit, as I understand it is directly related to Ph, and my Ph is at 8.3. Is that correct? I am lacking on the lighting department, just running two 40w NO flourescent right now, saving money for the metal halides.

I look at my overflow compartment and notice the top part that is exposed to lighing is heavly encrusted with corline algea. The area that gets no light has absolutly no coraline. There is a relationship. I don't think yours will start spreading until you get better lights IHMO.

Would you agree, Lew, that the SeaChem kit is a good kit, though? I agree with the rest of your assessment in general.

Btw, I was able to grow T. derasa and LPS with a bank of NO fluoros with great results - back in the day.. <chuckle>

Seamaiden, I didn't comment of the seachem test kit because I have no personal experience with that particular brand. I use Salifert only.
