It seems now that I'm BB, I have a different kind of algae problem as compared to before with the DSB system. I guess you can't live without them & you can't live with them to some point. Razor algae, I had this in both systems, anyone has ideas on how to rid yourself of it, please let me know, this stuff can't be killed. The only way I found to work is plucking the rocks clean, leaf by leaf or extreme boil then pressure wash the rock, even then it still won't go away unless you pluck it away. The good thing, it grows slowly & I'm able to control it so far. The main algae problems I face is the light green type, easily blown off rocks in most cases, but must be done continuously daily it seems, I get some brownish hair type algae on the back glass section where I don't clean regularly. I think most of my problems might just be my fault, I have three fish, Hippo, six line, & one Engineer goby I wish I could catch. I siphon the areas that collect waste, usually all in one corner. That is about my worst spot for collecting trash. I filter sock every now & then, with a 5 micron sock filter. I run carbon 24 & 7 also Rowaphos at times. I'm looking into a canister system for these two instead of socks, I know they won't allow for the surface area needed. I also skim as wet as I can, I usually fill a container twice a week. I have about 200lb of LR, which I removed about 50lbs three weeks ago due to algae. The 50lbs of LR is in a tub with a PH & heater, looking better but I'm going to let it cook a few more weeks longer. I recently replaced my lighting, MH & VHO & I have about 35 X turnover in flow, like I said most of waste moves to one easily accessible corner. I also make sure feeding is not excessive, I really don't have to feed much because the Hippo grazes & I just supplement a little extra for protein & nutrients. As for as the six line, goby, snails & crabs I don't know what they eat because I try to not feed them also my cleaner shrimp. So I guess I need to make some changes, I think I will end up cooking most all of my LR, doing daily WC's until I can later tear it all down and move the tank across the house. As for as corals, they seems to all be doing great Except my yellow leather, it opens up but never like before. been like that for several months, thinking I may need to try and relocate it once more. So my question is, in a BB system, just what are your routines, what are you doing to keep nasty algae's away. Is a BB system the same, when it comes to house cleaning, should I be doing more frequent WC's? Is it only me that have similar issues, before with the DSB I had different algae's, now these seem to be grouped accordingly. Maybe after three years I need new LR?
