Desperate for answers on Mustard Algae

Yes, the pooltrine 60 from Leslies is polyquat. I have used a hand full of brands (polyquat) over the years but this is by far the best price ever!!!

The biggest complaint anyone has with polyquat is the price but that argument vaporizes at $5 a quart.

John,

I dealt with Mustard algae 2 years ago. The pool store made things 100 times worse! This forum saved my bacon. I have a 17,00 gal AG pool with a DE filter.
This is what I did:
1st you need your stabilizer level at at least 30 otherwise the sun will start destroying your chlorine as soon as it comes out. Closer to 40 would probably be better. Keep you chlorine b/t 10-15 at all times(use calculator to determine). Add 1 quart of POLY- Poly[oxyethylene(dimethyliminio)ethylene(dimethyliminio )ethylene dichloride] 60% algacide immediately and then another qt in 3 days. Leslies Poly 60 is "Step 4 algae preventer" (link= http://www.lesliespool.com/shopping/...ProductID=8110). I don't know if POOLTRINE 60 is the same! Seems awefully cheap to be true? Do not use yellow out. Trust me! (Or copper for that fact) Only use the Poly 60.
Get your PH as close as possible to 7.3-7.6. If you go too low add a little Borax to bring it back up. Don't worry too much about alkalinity is should stabilize around 100 when you ph stabilizes.
Vacum to waste- not through your filter. Keep in mind that most tap water has a high PH so if you need to add water you may need to compensate with the Muriatic Acid(use small amounts). Also rain has a low ph and a significant amount can lower the PH in the pool. Add Borax to compensate if needed(use small amounts). My algae was gone in a week and has never returned! I use 4oz of poly 60 every Sunday and add about 4 gallons of bleach per week to keep my cl level around 5ppm(stablizer is still around 60-was at 120 when the pool store got done with me-thats another story. My pool has been beautiful ever since. I thank Ben and this forum everytime I go swimming This should work if you can keep your cl level up throughout the day. Try to keep your filter running as much as possible to keep the water circulating and vacum as much of the algae as you can out of the pool. I would probably wait a few days after the 2nd dose of poly 60 before swimming.

Good luck, Joe

poolrx,
I have attached a pic of the active ingredient in pooltrine 60. It looks to be the same as the POLY ingredient you posted above.

I see no reason to pay $22 a quart when the pooltrine in $4.83!

Nice! Thank You. I guess they are clearing house at Leslie's. That is the stuff

That's a GREAT price! I cringe at paying $19.95 a quart and wait till it's $15/qt or less and buy a bunch and they go in my basement. But under $5 is amazing!

I received my Pooltrine 60 from Leslies yesterday. It's Polyquat 60%!

I see they also have a Polyquat with a Leslies label called "Algae Control" for $23 a quart.

They are probably liquidating the Pooltrine 60 from stock.

I think I will try to get a quart of Polyquat 60 today and throw in. Things are looking much better. I am still getting a very small amt. of what I would assume is DEAD algea at this point, and it could be coming from my PoolBuster Max CG, that is sucking in, and coming back out, not staying in the filter bag, even tho it is the extra fine bag. I have made sure that I am AT 15 PPM, almost around the clock since this thread started, and have vac'd almost every day, and brushed on the other days. Tomorrow, I am going to vac to waste. If I do vac to waste tomorrow, I will add the polyquat to it after the vac to waste. Will that be too soon, since I added CYA to the pool on Saturday (if memory serves!)? My CYA is up in the low 30 range. I will recheck when I get back from vacation and see if that needs to go up a tad more. I only lost .5ppm of chlorine last night, and there was a grub worm in the pool this morning that could have been responsible for that loss. If I don't vac to waste, I will just use the poolbuster tomorrow and Saturday morning, before I leave town for the week. I don't want to chance losing any stabilizer if it is too soon to vac. to waste?

Thanks,
John
