My CA is at 400, but corraline algae not proliferating..Help

[vwelter]

My tank is about 8 weeks new, and was stocked with prime cured Fiji rock(100 gal tank/150 lbs rock with deep sand bed)...great quality covered with corraline....it cycled quickly, and now all my water quality parameters are perfect, and have been for about 3 weeks. There is definitely growth of corraline on the rocks themselves, but I'm getting none on the walls of the tank...like I see all over the tanks at my LFS. I'm just getting alot of tiny specs of what looks like brown/yellow algae? I'm using B-ionic Calcium buffer system, and as I said earlier my CA is holding steady at around 400, Alk is high-normal, pH is 8.3 and everything else is good. My lighting set up is a single 400W MH 20000K and 2 PC 65/55w actinic/daylights. Any suggestions?

Hi vwelter,

Give it time. It takes awhile for coraline to spread throughout the tank. Especially to the walls and glass. That comes with a mature tank. The fact that you have live rock covered with it is a great start.

Best of luck

I agree patience is probably all that's required. I find coralline grows best in high current. Do you have lots of flow? Keep your params up and it WILL grow.

Be happy - there is nothing that you will hate more than scraping coralline algae off the sides!!

Dosing magnesium will help in some cases.
