Massive algae issues

Thanks for the reply. The bleach I used was some that I picked up on sale at the local grocery store. It was value time bleach, I think. I just picked up some walmart brand stuff today.

I need to make a couple of corrections to the original post:

The test kit is a Taylor 2006A and my filter is a 25gmp sand filter.

Thanks again!

Quick update:

I added the bleach as you suggested and finally got to 21.5ppm last night, lost 5ppm by morning and added 9qts of bleach. I took a sample at 1:45 today and got 20.5ppm, so I added 6qts. It looks like I'm starting to get ahead of it. Thanks again!



I have a little more clarity on the pump/filter. The filter is a Hayward s144t sand filter with a filtration rate of 25gpm at 50psi which holds one 50# bag of sand. The pump is a 1hp 40gpm hayward. Sorry for the lack of info. The stickers on the filter canister came off and i had to do alot of digging to get the right info.

After doing a bit of reading on the forum, I think I'm greatly over-pumped and under filtered. I went to the hardware store today and picked up a ball valve and installed it on the pump discharge. Under normal conditions the filter usually runs at 12psi, so I throttled it back to 6psi after I backwashed. Hopefully that will help the filtration, as I currently have only about 8" of visibility. If this doesn't help, I'm gonna try some D.E.

Looks like you've done the homework--congratulations!!

You're doing it all right--just stay the course and let us know how it's going.

Shure will, thanks.

I may have found a replacement filter, a 300# Hayward S244S for $200 localy. Would this be overkill for my pump?

No, it will work well, BUT you'll need to be careful in your plumbing so that you can deliver 40 - 50 gpm to the filter during backwash. If you can do that, you should get excellent performance from that filter.

If you can send pictures of your pool & piping layout (send to poolforum@gmail.com) AND tell us the model of pump you have, we can probably make some suggestions.

Hi Ben,

The pump is a hayward s48e48a04, 40gpm 1hp. I can't take a pic of my setup at the moment, but I replaced the pump discharge hose with sched. 40 1 1/2" pvc piping. My drain hose is also 1 1/2".

That's the AO Smith motor number; possibly on a Hayward Power Flo or Power Flo LX. You need to look on the plastic part of the pump, where the pipes connect, for a label with an SP number, like SP1540C
