Desperate for answers on Mustard Algae

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

Hi, John,

Sounds like your on the home stretch. Just a reminder....don't give up. Keep that Cl right up there 'til your water looks like you want it to.

I have never been a big proponent of vac to waste. I think a lot of it depends on your filtering capacity. I am lucky to have a huge filter.

If you have gotten this far and you feel like your filter is doing a pretty good job....I'd let it do the work. Of course simply vacuuming in the "filter" position is very helpful.

Good work, John. Keep your Cl up.

John you don't have to vaccum to waste. I suggested it b/c a. the algae clogs the filter much faster and b. Mustard Algae is very resilient and getting out of your pool reduces the risk of reoccurances. You would be suprised how little adding an inch of fresh water affects the pool chemistry(at least in my pool). Since you have been having a problem with the ph bottoming out it may actually help to add fresh water.
Also should have added some more detail regarding vaccuming. By vaccuming I mean to get out the large deposits sitting on the bottom. I would only vaccum long enough to get them out. I would angle my return so that the flow of water would push everything to one side. Don't be afraid to add the poly 60 as it has no negative affect on ph, cl, etc. I have had great success with it the last 2 years.

Good luck and enjoy your vacation, Joe

John,

With an inground pool you pump should have a bypass valve that allows you to pump the water directly to waste before it reaches the filter. You don't want backwash your filter since you recently added the stabilizer(unless it is clogged from the algae. Is it DE or sand.
