I've recently posted about the cyanobacteria that has begun to grow on my sand. I've also got other stuff growing that is making the sand like a specled brown. I've noticed in looking at pictures of oterh peoples tanks, even the very nice ones, that a lot of people have the brown stuff on their sand. In reading about how to remove the red slime some posts state to increase water flow, some state that does nothing...others state to cut back the light while some say that the cyano does not need the light to spread. The thing is that the whitest sand in my tank is found in locations under the LR, like on the sand in the caves that I made out of the LR. In looking at my tank I'm thinking that these areas receive the least amount of light and have the calmest water. So what is the deal?
I'm going to do a water change tomorrow, probably around 15% because that is all the change water I will have, I will siphon the sand, change my carbon, make new change water then do another siphoning and water change in a few days. I'll try this for a couple of weeks and if that doesn't work looks like I'll have to try the chemicals.
Ideally, should the sand stay as white as it was when it was in the bag? The sand I use is CaribSea Arag-Alive Special Grade (20 lbs) and Arag-Alive Bahama Oolite (40 lbs).
TIA
