Cleaning algae from a dried pool

Postby mlitsonata » Wed 04 Sep, 2013 11:37

Hello,

I'm the new manager of a hotel that is in pretty bad shape. I'm working on the pool now. Not only was it a swamp but a lot of renovation work needs to be done to bring it up to code. The only thing that seems to be sound is the structure of the pool itself. It's going to be a while before we can get everything up to code and it was recommended that we drain the pool for now.

So I've drained most of the pool so far, it's still pumping, and now we have the nastiest algae mess I've ever seen on the bottom. I'm guessing the deep end could be a good inch think when it's done. Unfortunately I couldn't shock the water first to kill most of it because the pumps are all shot and need to be replaced.

So, my big question. What is the best way to clean up this algae? Some has dried on the first few steps and when I went to clean that up to get a feel for it I found that it seems to dry like cement! I thought I could just brush it away, haha, suuuure. I'm guessing I'll need to use a hard brush to loosen it up and then sweep it away. Talk about a lot of work! Any suggestions?

get liquid chlorine and pour it from the tile down around the sides of the pool walls all the way around it let it stay on 5 mins or until algae turns color. Know its easier to pour using a plastic jug that you use to water plants just cut off the tip so it pours nice like a hose. Then gets the hose with a nozzle to help get all the dead algae off the walls then do the same to the floor. This all being done I assume with you using a sump pump I assume. Its called a chlorine wash

Hello,

I just want to add too Free Info's advice there, that the chlorine wash is what you need after you completely cleaned, shoveled, bucketed, all the solid algae mess out of the pool.
Keep in mind, you will want to perform a chlorine wash in the morning hours and not during the heat of the day. There's a few reasons for this; the first being, the chlorine fumes are strong, and will irritate the nose passages and lungs a little, enough to almost knock you down if you get a strong whiff. Second, the chlorine will not evaporate quickly in the morning. It will stay pretty liquid allowing the chemical to kill the algae.

A few safety reminders as you work with chlorine during the wash
- wear clothes you don't care if they get bleach stains
- wear nitrile gloves to protect your hands
- please feel free to wear a cartridge type respirator you can get at most hardware stores to protect your nose from the strong fumes. I find they work great and the fumes don't bother my breathing.
- goggles! It's going to happen. It will happen. Chlorine will splash in your eyes. No matter how careful you think you are pouring, *splash*, right in the eye.

have a garden hose with a high pressure nozzle handy at all times and have fun!
