Intex Pool Problems. Please Help Me. Nobody Else Can.

by Stephanie

I have a 16 x 48 Intext above ground pool. Have a larger pump and a salt water filtration system with it. We only have well water which has alot of metal in it.


Started with 160 pounds of salt (didn't know about the bad water) and the water turned green. Tried to shock and it stayed clear green color. Checked test strip and it said pH of 8.4 and alkalinity of 240 ppm.

Went to pool store and took sample. The pool guy gave me Metal Magic which I put in immediately. He said my strips must be wrong and alkalinity is low and pH was 7.4

I bought strips from him and put some alkalinity increase and pH down as he told me to (did alkalinity increase slowly as advised.)

We have been changing filter and washing it out every few hours and applied a tube sock (learned on internet) onto skimmer and have been washing it out every few hours. The well water puts out some rust colored mess on skimmer but not hardly any filter. I heard that Intex filters/pumps suck.

Then 30 hours later still have clear green water. Used the pool store's test strips and it gave me same reading pH 8.4 and alkalinity 240 ppm. Used other Walmart brand strips and got same results. I was so mad.

So his testing was bad or there needs o be a recall on all Aqua Chem strips and Aquachek strips. This is driving me crazy and my kids who are begging for pool.

Some places on internet say to swim in green water its ok but my pH is sky high and alkalinity is sky high.

Please help me. I don't know the right order to do things. Do I wait a few more days for Metal Magic to work? Should I shock it? Why were my test results different from pool store?

Please help...I'm losing my mind and all my money.




Thanks for the question Stephanie

We'll start at your pool size. I believe it's about 21,000 gallons. For an average 20,000 gallon pool you will need 7-10 50lb. bags to bring your saline level to the correct reading of 3000-4000. Be sure you know the correct range for your salt water chlorinator (SWC).

Well water, as you know, normally has metals in it, copper and iron being the most prevalent. You need what's called a metal sequestrant.

A metal sequestrant does not remove metal from pool water. It holds it in solution until it can get filtered. Then you backwash the metal out. Because metal sequestrants break down over time and get filtered and backwashed out, you need to weekly dose your pool if you have high iron and copper. Metal sequestrants that are based on HEDP, phosphonic acid or something similar are the most effective.

Jack's Magic Blue, Purple, and Pink Pink Stuff, Metal Magic, Metal Free, & Metal Klear are very good.

I'd encourage you to get a Taylor FAS-DPD K-2006 pool test kit. Test strips are convenient, but the K-2006 kit is the most accurate. Another good kit is the TF-100. The K-2006 kit should be the one the pool store uses. If they're using strips to test customer's water I'd either do it myself or try to find another pool store. A pool store employee should never use strips. If he does, it's either because he's lazy or doesn't know what's he's doing.

What you need are the right numbers and the K-2006 kit will give that to you.

A clear emerald green pool means there's metal in the water after a shock. Unfortunately there's no way to remove metals from the water other than replacing the water with new water that doesn't have any metals in it.

Here's a good post with the exact same problem as yours:

You need to know the CYA (cyanuric acid/stabilizer) level. It should be between 30 - 50ppm. If it's too high, above 80 or so, you'll need to do a partial drain and refill.

Let's say that the readings are correct. Your pH is 8.4 and alkalinity is 240. First you need to get the alkalinity down. You'll use muriatic acid for that.

Then the pH:

Honestly you're not really too far off. It may seem impossible to get the water clear, but you need to remember that you're dealing with high metals. You're going to need to use the sequestrant often and backwash to control them. The metals plus chlorine will turn the water a clear emerald green.

Solid green water is algae. This means a lack or chlorine or the chlorine can't do it's job because of either too high or low CYA.

Emerald green water is metals/chlorine/pH problem. Each one must be fixed differently. You can't get an emerald green pool clear by shocking it. A shock is for algae.

Get you a good sand filter. The Intex cartridge filters are a joke. Run the filter day and night adjusting pH and clorine. The alkalinity will drop gradually by the aeration of the water.

This is the only way to get it down. Rain water will help. When it starts clearing up back wash the filter to get the green stuff out. Be patient you will get there.
