Let's keep this thread alive.
I've had the same algae (see post #63, and post #309) for several months, and can't get rid of it. As stated in other posts, it seems to thrive in very clean, low nutrient water with good flow. I also believe that, as stated earlier, it out competes coraline algae for certain elements needed to grow, including magnesium. I've had this tank set up for about 8 months or so, and I used the rock from my old tank. The rock had plenty of coraline on it, and no red algae. I have had almost NO new coraline growth in this tank, but the red algae is growing like crazy.
There may be some posts here where the person had a different type of algae, and turbo snails worked for them, but they didn't do anything for me. I put 3 Mexican turbo snails in the tank. I took them out after about a month because I didn't see any difference, and I got tired of them knocking down my corals. This algae may be to tough for them. I also tried a few blue leg hermits, but got rid of them too. I never saw them eat the algae, and got tired of them taking out my snails.
I may try a Longspine Urchin next, but I'd like to figure out how to stop it from growing rather than relying on some critter that I really don't want in my tank to keep it under control.
Is there anyone out there that's found the proverbial "magic bullet"?
Thanks in advance
