Algae bubble clusters floating on top of water

[SherrieDee]

Well, moving right along...did a 50% drain and refill yesterday and tests today are as follows:

FC 1.5
CC 0
TC 1.5
pH 8.2
TA 190-200
CH 375
CYA 58

Water still crystal clear...vacuumed leaves, etc.

Next step(s)?

CYA we round up to the next number so you are at 60. You need to raise your FC to 8 or so and lower your pH to 7.5.

Sherrie- I'm sorry I've been out of town and hadn't gotten back to you in a few... letsee...

FC is still too low.
CC of zero is good!
pH of 8.2 is still too high- have you used the muriatic acid yet? You need to have PoolMath guide you on how much to use so you don't under or over dose it. Do you need help with this?
TA will come down if you'll get that MA in the water and lower the pH as necessary over time.
CH is good.
CYA is 60... so keep your FC at least 8ppm at that point. It should be enough to allow for normal daily loss without going under your bottom line FC level of 5. Are you using the bleach??

Well, moving right along...I think I'm getting close now. Readings from this morning:

FC 8.5
CC 0.5
TC 9
pH 7.5
TA 80
CH 400
CYA 50

Water still crystal clear...maintaining vacuuming...will use poolmath chart to keep FC correct using 8.25% bleach. I used the MA repeatedly to drop the TA and aerated which seemed to help.

Advice on tweaks?

Also, planning on doing the annual cartridge filter cleanse using a 5-gallon bucket. What are the proportions of water to acid?

Also, I'm in San Antonio and am wondering how long I should be running my filter daily and if there is a prime time to be running it.

Thanks for all your help.

See this on filter cleaning - Pool School - Maintenance and Cleaning of Pool Filters

I do not ever use acid when cleaning my cartridge filters. I have used TSP to soak them in to remove grease (sunscreen, lotion, etc).

Run time during the winter can be pretty minimal. See this for overall run time suggestions - Pool School - Determine Pump Run Time

Take care.

Just wanted to thank all who responded for all your help. The pool is now well and doing great. I just have to keep my chlorine stable but it is now a breeze to test and adjust using the poolmath calculator. It's crystal clear and I feel like I finally have a handle on it. Thanks to all for your help.

That's *great* to hear, Sherrie! Next year should be a snap and you'll get to enjoy the pool so much more.
