What will happen if I wash the hair algae off my live rock under freshwater? Maybe a stupid question but I'm tired of battling the hair algae.
 
You will end up killing a fair amount of fauna and coralline that way. Depending on the crew in your tank, the easiest way to deal with hair algae is manual removal and greatly reduced nutrient. The main culprit will be PO4 in most cases so I would suggest getting that tested and ensure you only use a pure water source like RO for top off and water changes.

Once you eliminate the cause, the algae will usually go with it. A good way to remove it is with a toothbrush. It's a bit labour intensive but very effective. Once trimmed down a kept short, the animals will have a better opportunity to control it. If too long, most snails and hermits will simpley ignore it.

I have to take it out and scrub it about each time I do a water change. I have a phosphate test kit and it tests good, I also use RO water for changes and top offs. I feed once a day and try to limit the amount I give them. Any other ideas??

Good would mean undetectable. Any amount of measurable inorganic phosphate would mean the presence of high organic phosphates that would continue a nasty cycle allowing it to fuel the algae problem...

Your routine seems fine except for the need to remove the rock. How's the tank set up/age, animal load including mobile inverts and what is the main food you use?

My profile lists my tank set up. I did a po4 test yesterday and it was 0. I mostly feed flake food and occassionally toss in a little frozen brine shrimp. I also put in some phytoplankton for the scallop occassionally.
 
Cutting back on the flakes will help. They can be a great addition to a feeding routine but should not be used too heavily. They are loaded in organic and inorganic phosphates and will continue to fuel the algae problem.

If the only fish is the tomato clown, I would just use some mysis soaked and drained to remove excess PO4 and then add a few drops of Zoe to fortify it. You should notice a difference in about a week. An added benefit would be using a PO4 granular sponge for a day or two to help reduce the organic phosphates. I realize you have said the test reads zero for inorganic phosphates but if the tank had no PO4, you would have no algae problem... :wink:

Sorry missed the fish at the end of the profile :oops: . They will be fine with the mysis as well.

What is mysis and zoe and will my LFS carry it? I live in a pretty small market.
 
Selcon is an excellent product but becareful on how much you use. For a larger tank it's generally not a concern but in a QT, the higher concentrations of [acronym="Highly Unsaturated Fatty Acid"]HUFA[/acronym] and lipids can create water quality problems. As long as you do a few extra water changes, it should not be a concern though.

Scarlets also are a great additon to a cleaning crew but for manual removal you might want to attach a clean toothbrush onto you vacum so everything you pull loose goes into the trash water
 
I really appreciate all the help!! The idea of attaching a toothbrush to the vacuum is a great idea! I'm looking forward to trying it out. Another thing I've done is using the power heads manually to blow the algae off of the live rock. Thanks Again!! Hopefully I'll get rid of this stuff. I might try posting a pic so I know exactly what I'm dealing with.
