How much copper sulfate would you use in a 30000 gallon pool?

Answer 1

It is best to steer customers away from algaecides that use copper, since copper tends to have bad effects in pool water, i.e. stains on the walls, and cloudiness after chlorine is added etc. Sodium Bromide based algaecides in conjunction with liquid chlorine is usually the cheapest and most efficient method for destroying algae. Just make sure that you don't have a mineral purification system (nature2, pool frog, etc) or the Sodium Bromide (or the copper for that matter) will instantly destroy it. Yes but not straight as it will mark the walls and break down quickly you do need to buffer it (doing this will make it last approx 10 times longer) and adjust its pH to 6.5 and still use small amounts of bromide or Chlorine from time to time. as there are some bacteria that it doesn't control First thing you need to do is make sure your alkalinity is at least 50 ppm for copper sulfate to work properly. My pool used to be totally dark green when I opened it. I now use 2 to 3 table spoons of copper sulfate when I open it in the spring and it goes from green to clean in about 2 days. It may be a little cloudy after this, but it's something you can work with, clarifiers etc. Also back flush often. I also use the same amount in the fall when I close it, but make sure you circulate the water for 2 days before you close it. Make sure you mix the copper sulfate with water in a plastic container, make sure the blue crystals are dissolved. I use a 2 gallon plastic container with a sprinkler head on it like you use to water flowers with, this makes it easy to sprinkle the copper sulfate mixed with water in the pool evenly. You can buy copper sulfate at your local hardware store or on ebay.

P.S. I only use use copper sulfate in the spring and the fall. I do not use it during the season as a chlorine substitute as some people say they do, as to much copper in your water can cause you problems.

Zero. Hmmm, maybe you also need to clean the filter. Did you follow the label directions explicitly? Just what was in those "kits"? For plaster pools only : Find and use - according to label instructions - Yellow Treat by United Chemicals or Yellow Out by ( can't remember), adjust pH, 4 to 8 gal 12% liquid chlorine - as per label - 24/7 filter run time, brushing pool minimum 2X per day, back wash filter - as pressure increases to 5 # above "clean pressure". Next day test chlor level and add more liq. to boost so that you maintain 10.0 ppm. When your pool water is crystal clear -- back wash again. When the water has cleared you may then reduce filter time to 6 -8 hrs. -- when chlor. levels drop to below 5 you may resume using pool and maintaining chlor 1.5 -3.0, pH 7.4-7.8, alkalinity 80-120ppm.

Clean filter, proper levels of chem equal a pool without many headaches. Remember it is a money pit. Copper sulfate is illegal to use in most states... too toxic.

First of all I'm not a pool expert, but I've owned a pool for a bought 25 yrs. I live in Ohio and I have a 20,000 gallon vinyl liner pool with a sand filter system. First thing you need to do is make sure your alkalinity is at least 50 ppm. for copper sulfate to work properly. My pool used to be totally dark green when I opened it. I now use 2 to 3 table spoons of copper sulfate when I open it in the spring and it goes from green to clean in a bought 2 days. It may be a little cloudy at first, but When you get your alkalinity, chlorine, stabilizer, and PH where it belongs it will clear up. I also use the same amount in the fall when I close it, but make sure you circulate the water for 2 days before you close it. Make sure you mix the copper sulfate with water in a plastic container, make sure the blue crystals are dissolved. I use a 2 gallon plastic container with a sprinkler head on it like you use to water flowers with, this makes it easy to sprinkle the copper sulfate mixed with water in the pool evenly. You can buy copper sulfate at your local hardware store or on ebay. I'm sorry this information is so long, but I know what you're going through, because I've been through it. I hope this helps you.

P.S. I only use copper sulfate in the spring and the fall. I do not use it during the season as a chlorine substitute as some people say they do, as to much copper in your water can cause you problems.

My suggestion... #1 make sure there are no circulation or filtration issues. #2 Check your existing copper level... then balance water as needed...PH should be at 7.2 - 7.8 Alkalinity AT LEAST 120ppm and make sure both free AND total chlorine match, Stabilizer (cyanuric acid) a minimum of 40ppm. (personally I like to keep it at 70ppm) and calcium at the same... 120ppm up to 400ppm. Now, assuming that your copper level is a 0 you can then proceed with superchlorination... If free and total chlorine do NOT match this must be corrected before proceeding to algae treatment. In pools that free and total chlorine are not the same breakpoint will have to be achieved using Lithium Hypochlorite, Calcium Hypochlorite, Sodium Hypochlorite, Or Dichlor. Dichlor has fast become my favorite method of both superchlorination as well as for killing small cell green algae. (the type of algae that turns the pool water green.) The biggest problem in clearing water is that pool owners backwash too much... It is much more effective when you wait for pressure to build and actually begin collecting the smaller debris.. you should not backwash until filter pressure is at least 10 psi over NORMAL starting pressure... or until the flow is significantly reduced coming from the eyeballs of the pool. PLease use caution when using a copper based algicide. You WILL want to use one with a built in Chealating agent or will want to follow up with one as copper will never ... I hope I helped! :)

Enough to shock the water. First of all I'm not a pool expert, but I've owned a pool for a bought 25 yrs. I live in Ohio and I have a 20,000 gallon vinyl liner pool with a sand filter system.

I now use 2 to 3 table spoons of copper sulfate when I open it in the spring and it goes from green to clean in a bought 2 days. Make sure you vacuum dead algae out. It may be a little cloudy at first, but when you get your alkalinity, chlorine, and PH where it belongs, it will clear up. I also use the same amount in the fall when I close it, but make sure you circulate the water for 2 days before you close it.
