    No you'll be fine, just keep an eye on your pressure gauges etc. Algae can technically damage vinyl but chemicals are much more likely to do damage.

    Re: installing New equipment in Pool with a lot of Green Algae

    Hi, Thanks for the help. I was thinking of using Polymer Algaecide and would it be ok to Shock the pool that evening, using 2 LBS per 10,000 gallons? Also are pool is in Concord, CA not planning to swim to much more.

    Thanks

    Welcome to the forum, QC

    Would hesitate to recommend use of an aglaecide before knowing a lot more about the current treatment and most recent test results for your pool. (Current levels for pH, FC, CC, CH, TA and CYA. If you have these numbers, please post them.) You may already know that liquid chlorine or bleach can be a very effective tool for shocking your pool, and nothing else is added to the water that you have to deal with later on. If you have a few minutes, please take the time to read these two short articles:

    TF Test kits' TF100 - the link is on our home page. Otherwise the Taylor K-2006, purchased online is your best bet. It's VERY unlikely you will find a recommended test kit in stores.

    Lots of folks here use the TF-100 and possibly an equal number use Taylor K-2006 or Leslie's FAS-DPD Service Test kits (be forewarned that Leslie's stores don't always have this in stock.) All are priced at less than $100 and will last a long time. Here's a link that discusses relative merits of each:

    Re: installing New equipment in Pool with a lot of Green Algae

    Thanks everyone for the help I will call up Leslie’s for the test kit. The one I have is a very basic one but I did take some levels the first is FC is about 2.0 and the PH is 7.8 not sure what I should add to the pool for the algae

    The easy answer to your question is... chlorine! But post test results first and the people here can help you through it. BTW -- Be sure the Leslie's kit you purchase contains the FAS-DPD chlorine testing components... not all of theirs do.

    That's easy, more chlorine. You have algae because there isn't enough chlorine in the pool. It's hard to know how much you need without some other tests, but bringing your FC up to 10 would have to help and would not harm anything (except the algae).

    What kind of chlorine do you use? (The ingredient, not the brand name.) Around here we recommend "liquid chlorine" aka sodium hypochlorite, better known as "bleach." Regular unscented bleach works great and is cheap and easy to find.

    Keep posting your progress, somebody's almost always around to cheer or advise.

    Re: installing New equipment in Pool with a lot of Green Algae

    Paulr, I did not know that regular bleach from the store would have much effect on bring up FC and also kill the algea. Can you do this even if you have a SWG?

    Not PaulR, but YES!! In fact, we recommend using bleach or liquid chlorine to shock your SWG pool!!

    Bleach is a lower concentration (usually 6%) of pool store liquid chlorine (10-12%). Shop around a bit... some folks find it is more cost effective to buy the LC, and in some areas, bleach is the better deal!

    "Shock" is a process, not a product!

    Re: installing New equipment in Pool with a lot of Green Algae

    In 5775 gallons, one small (96 oz) jug of 6% bleach (e.g. Clorox) will bring FC up by about 8.
    (According to the Pool Calculator.)

    If you have an SWG, it seems to work best to use that for maintaining an FC level, but for shocking you are better off using bleach (or whatever) to bring FC up. That way the level comes up right away, you're not waiting on the SWG.

    Re: installing New equipment in Pool with a lot of Green Algae

    Paulr and Mermaid Queen, thank you for this info. I do not have any numbers to post yet, however I have noticed some light mustard colored algea and I suspect that it is due to low chlorine. I thought about shocking it however I did not know what kind of schock to use. The water is crystal clear and the PH rises every week so I put in about 20 oz of muratic weekly. Last month I took a water sample to Leslies and the numbers came back perfect.
    I will post some numbers later.
    Thanks you for your direction and support
