Iron in Swimming Pool Water

by Traci
(Caledonia, NS, Canada)

I have a Hydro Force above ground swimming pool and use the Krystal Clear salt water system.


I filled my pool from my tap water which is run through a water purifier. This year my pool water turned a faint shade of brown. My house water has a high iron content. How do I get the iron out of my pool?

It happened last year but I just emptied the pool and wiped down the bladder and refilled the pool. It worked, but I don't want to do that this time.

Is there anything I could add to the pool that would remove the iron without harming the filter or salt water pump?




Thanks for the question Traci

There's no chemical that removes metals from swimming pool water. What you need is a metal sequesrant.

Well and some tap water has lots of impurities, namely copper and iron. You can use a good metal sequestrant to try to get rid of the heavy metals already in your water. You can have your iron level tested at a local pool store.

Metal sequestrants that are based on HEDP, phosphonic acid and/or its derivatives are the most effective.

Some popular brands are Jack's Magic Blue, Purple, and Pink Pink Stuff, Metal Magic, Metal Free, & Metal Klear.

This is normally not a one shot deal. 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 will need to add a bottle once per week.

Troclosene

by Joey S.
(Tel Aviv, Israel)

Thanks for a great site. We have an Intex 8 ft round pool, which holds about 640 gallons. My question is whether it is safe to treat the water solely with Troclosene 1500 mg tablets, which we found in our local store.

The box says to use 2- 3 tablets every 3 days and that's it, with no need to test pH or use any other chemicals.

It seems too simple and therefore good to be true - what is your opinion?

Many thanks

Joey




Thanks for the question Joey

To my understanding, dichlor (dichloroisocyanuric acid and dichloro-s-triazinetrione and troclosene) are basically the same chemical makeup which is Cyanuric Acid (CYA).

Sodium dichloroisocyanurate is used as a disinfectant. When added to water it has the same properties as hypochlorous acid, which is essentially chlorine.

I would be very hesitant to rely solely on Troclosene. While it does have disinfectant properties as stated above, my understanding is it can be rendered less effective if the pH is allowed to get above 8.0. The alkalinity plays into the equation as well. Keeping that between 80 -100ppm will also help facilitate the chlorine.

A one-stop-shop and there it is, everything is fine and nothing else to be done, has not been my experience since taking care of hundreds of pools since 1999.

Keeping your pool water balanced takes time, knowledge, and effort. You can minimize it through proper techniques and information, but you still have to do it.

I would encourage you to take the time to get and keep your pool balanced. Take all the readings at least once, preferably twice per week, and make adjustments as needed.

Until the pool industry comes out with the "magic pill" for pools, (I don't think Troclosene is it) I'll keep doing it this way.

Brown Tea Pool Water

by Toby

My pool filter doesn't clear up the water that has been shocked and turn into brown tea, its been 5 days and i notice it didn't settled the rust completely after vacuuming it. year ago, we manage to clear our pool into crystal blue green (not really blue) by just shocking and let the filter do its job. but now the filter seems like doesn't clear my pool, i usually backwash and rinse. but still no changes.

Another question is, i got a sample of the water coming out to the returns(waterfalls) and put it in a bottle and the water isn't "clear" its the same color of the water in my pool. Its clear but not that clear (blurry) dues to chemicals. from what i know the water in the returns should produce clean water.
