best algae eater?
Well you need more snails....no more hermits......I would get some of the large turbos.....2-3.....some nerites and astrea.....10 of each.....and some for your sand....nassarius 10 too
as far as sea hares go...I believe I answered you as did Bang in your other thread......foxface are supposed to be voracious algae eaters too.
BUTTTTTTTTT....you need to find the cause too......IMO lack of CUC could be a partial contributor.....
what do you feed? How much? how long is your lighting on? You know the questions by now LOL
There's a pettern in your algae that I have seen before and it's pretty much the worst case scenario. I see some rocks with no algae and some completely covered. I've seen this before, fairly often.
Hopefully I'm wrong and it's simply excess nutrients in the water from overfeeding. Ultimately it is Phosphate causing the algae.
Couple questions to confirm:
1 - Is the top layer of rock in the tank live rock or was it base rock?
2 - If it is live rock, was it ever exposed to high ammonia levels? by high, I mean above 2.0ppm?
3 - Did you cure it or was it cured by your local store?
Phosphate is the problem. I guarantee it.
The algae on the sand can be eliminated first by feeding better food, and less of it. Are you feeding flaked food? (I'm guessing)
An algae scrubber of some type.
There are chemical phosphate absorbers, I've never used them but many here have with success and can give advice.
The rocks are going to be a problem. What happens when ammonia gets high with live rock is that it kills the animals that live in the rock. Good live rock has shrimp, worms, bugs, clams, all kinds of animals living in it. If these are killed by ammonia then the nutrients from the animal are adsorbed into the rock and slowly released at the surface. This is idea for hair algae because it is able to use the nutrients directly from the rock and no matter how low the nutrient levels are in the water it can thrive.
It typically takes about a year for all of the nutrients to escape. At that point the hair algae will quickly diminish.
A phosphate reactor is an easy thing to hook up....I'd look into one of them..along with the things Bang has mentiones
I would also consider manual removal.....and I see a lot of the rocks have nothing on them....so I would take them out scrub them in a bucket of tank water....and rinse them in a bucket of clean sw
this is not going to go away quick.....you will need to work at it....BUT I also am a believer in a good CUC.....you need something to help with the "leftovers" I made some suggestions earlier
