I have an algae problem. I have some, but not a lot, of red algae at various spots in my tank on the rock. I also have all over the back of the tank on the glass, as well as on the power heads and my canister filter in and outlet tubes a "furry" green algae, like carpet. It's only about an inch long at worst but there's a lot of it. It also breaks up easily with some a quick swish of the hand to invoke a bit of current.
I have recently added a brown tang in the hope that he'll help take control of it. The green algae doesn't seem to be on the rocks very much at all, but it is there just in a far lesser capacity.
My measurements are consistently as follows:
Ammonia - 0ppm
Nitrite - 0ppm
Nitrate - 0ppm
Phosphate - 0ppm
pH - 8.2
The salinity is 1.019 at the minute due to whitespot treatment but that has only been that way for around a fortnight. This problem with the algae has progressively gotten worse since my red faced blenny was killed by a mantis (don't worry, I've taken care of the mantis since) which was months ago.
I have a light period of 10 hours, consisting of 2x30watt white/day lights. I know I should have an actinic and will sort that out soon. The lack of an actinic has been for only around one month.
I feel either daily, or bi-daily either flake, nori on a clip or frozen mysis. It's fair to say that not a great deal of it goes wasted as I stand there slowly squirting small amounts in with a plastic suringe until they stop eating.
I have not measured silicates and so this is an unknown factor here.
Any help would be greatly appreciated. I can post some pictures later on if that'd help too.
