Garden copper sulphate for swimming pool


Hi. Water in my pool is green.
Need add aglaecide.
Options:
1. Crystal Blue Copper Sulfate Algaecide - Aquatic Grade Granular Pond Algae Control - 5 lbs $27
2. SeedRanch Copper Sulfate Pentahydrate 99.9% Crystals - 10 Lbs. $30
3. SeedRanch Copper Sulfate Powder 99.9% Pentahydrate - 10 Lbs. $27.77
3. Earthworks Health LLC Copper Sulfate Crystals-10Lb Bag (FINE CRYSTALS). Not a pentahydrate. $29.25
4. Something else, lots of product available.

Price does matter
Pool volume 35 kgal

May I use garden copper sulfate?
It's cheaper
Looks like I need to use pentahydrate, powder or Crystal?
Thanks

Look up the name brand with SDS after the name. The Safety Data Sheet says it's toxic if swallowed or with skin or eye contact.

Chlorine level 2/4 according to Wal-Mart's 6 way test strips.
But I put 25 3" tablets into pool 4 days ago and tablets still like new.
Water is green.

Ph around 7.2-7.5, I can't say exactly, test strips does not give good results.

Technician opened pool 2 weeks ago(rental house, owner send him), water was clear, but lots of green on walls and bottom, he did not clear it, he said that add chlorine and stabilizer. Also it was lots of worms on bottom. Pool was closed last summer and May be it was closed 2 or even 3 summers.

Water becomes green couple days after I clean it with brush(with hose)

25 tables for 35000 gal looks too much. But label says add one tablet per week per 10000 liters(pool 130000 liters as per technician)

Outbound pipe was clogged, technician just put new pipe over ground to pool. Looks like he plumber or even handyman, not pool technician, he put basket into skimmer and put brick into it, because basket tends to float.

Basicly I swimming in this swamp, but it looks terrible.

It May cause skin or eye irritation.
If swallowed drink large amount of milk.... rinse eyes.... Can cause cancer in California.

99% copper sulphate pentahydrate
1% inert ingredients
Same as aquatic quality copper sulphate.

Re: Garden copper sulphate for swimming pool


Do NOT ever use products in pool water not specified for the use. Pools are nice to have but a high maintenance item. Get the pool designated algae control required treatment and put it in as per instruction ounces per gallon. Do not swim in the water immediately after the product is put in. One should either pay the price to kill the algae or dump it IMO.

Even if a person maintains their water with the perfect "balance" as I did at work, while having to maintain a 250,000 gallon pool proved to me, algae gets in the water sometimes.

As the heat of the season rises, the pollen from the trees and bushes, grass clippings etc. can add to the algae problem, especially in the shadier parts of the pool. Starting in the beginning of every August, I had a heck of time controlling the mustard algae in the big pool. As it was surrounded by bushes, trees, homes that had their spraying fertilizers, herbicides, all contributors to some form of various algae growth . JMO

Re: Garden copper sulphate for swimming pool


I have used liquid copper made for pools....and it worked. Also, other pool techs use gallons of pool chlorine, per day for a few days, until it clears up. I think Nik333 has the right approach.

I would find another pool company and be upfront with them....that you need a month or two of their service to get your pool in good shape and than you will take over.

Re: Garden copper sulphate for swimming pool


Just realize that a pool requires a lot of work. You need to brush the algae every few days during hot months.

Don't add liquid chlorine until you see what the tablets do.

Patience.

But if you're renting, they should have made the pool pristine.

No, pool and not working hot tub rented as is.
House with 2 acres lot rented for price of regular house in this area.

3 large pines near pool, and lots of
cones and needles in water every day.

And that should I add into pool?
That about Clorox Pool&Spa Super Water Clarifier, $10 in Wal-Mart?

Should I put aglaecide into it?
Which one?

That is best place for chlorine, floating basket or bottom?

Re: Garden copper sulphate for swimming pool


With 35 tablets your stabilizer level would be sky high meaning which actually makes the chlorine work worse or not at all. The only way to get the stabilizer level down is to drain and refill, which from the sounds of it is your best course of action anyway at this point.

Also, if you've just thrown them in and they are sitting on the bottom you've also likely did permanent damage to the plaster or vinyl which can be expensive to fix.

You really do need to get a pro to take over. If you are insistent on doing it yourself, I'd suggest troublefreepool.com for help.

Re: Garden copper sulphate for swimming pool


As a retired CPO, even that pool water years ago would not pass my inspections. Pool water should be shimmering blue, with NO hint of green tint. IMO. If you are a landlord or maintenance tech responsible for pools, every cities health department has free classes for pool operators. One would really benefit you, as you are putting the swimmers in danger, as they are swimming in unsanitary water.

Is blue water result of color additive or it's possible without it?

Why fresh water in bath green like on pucture?

I'm my last apartment building, water in closed pool was blue, but it melted lycra from swimming pants and walls was stained with some white mass like chewing gum.
