How to get rid of mustard algae

I have an ongoing problem with mustard algae in my 10000 gal. in-ground pool.
Can anyone tell me what the recommended step-by-step procedure is to get rid of it?????

I don't know the answer but you might want to stop by your local pool supply store. They would know. They should also be able test a sample of your water to tell just what it needed.

I only get the pink algae here. The yellow is found in warmer where you are. It is not easy to get rid of. Everything needs to be cleaned and disinfected. You'll need the water to be checked for proper PH balance and then it will need to be triple shocked.

Rather then post all the steps here. This is site has it well explained.

You probably have the algae in your filter/equipment, so even when you appear to get rid of it with a normal chlorine shock, it recurs. It might also be that some survives a shock just above the water line. The key is to get rid of it all, so nothing is left to regenerate.

The approach to deal with it is fill the pool water level up high to sanitize above the normal water line, and triple shock the pool for two or three days with chlorine, making sure the shock water is circulating continuously throughout the equipment. Would be appropriate to first clean out the filter and soak with some bleach directly in it for a while before doing the shock routine.

In the future, make sure you have your pump equipment on and circulating at least half of the day, otherwise the water that sits in the equipment can be the breeding ground for the algae again.

Heavy shocking can alter the ph, so you will have to read the ph and alter with other ph up/down chemicals to maximize the shock effectiveness, and balance the water chemistry after the shocking is done.

I would use the non stabilized chlorine to shock, and keep the pool covered while doing this (the sun will degrade the non stable chlorine very quickly). Stabilized chlorine will withstand the sun, but the high chlorine level can be hard to reduce after the shock process to get back to normal swim levels.
