Switching From Baquacil To Chlorine

by Jeff Maes
(Pomona, Ca)

I have an Omega Supersplash above ground pool.

We use the Baquacil product but would like to switch to chlorine.

The filter system uses the Starite filter PLM 150.

Currently I have an algae problem that the Baquacil product isn't getting rid of and I don't want to spend (waste) anymore money.

I need a new filter and would like to switch now that I am getting one.

What is the process that I need to take to switch to chlorine?

Thanks for the question Jeff

It's amazing how many questions I'm getting this Summer about Baquacil and why people are either switching to chlorine or having problems with Baquacil or another kind of Biguanide pool.

Here are the steps you'll need to take for a proper conversion. Remember to have alot of chlorine on hand because you're going to go through it.

I'd suggest if you can, can get a cartridge filter. They're a bit easier, no back washing, easy to clean, and rate between a sand filter (low) and a DE filter (high).

And I'll give you the links to the chlorine, pH, and alkalinity pages.

Only replace the sand AFTER the conversion is complete. You don't want any Baqua products in there, to the best of your ability.

Here's the process of conversion:

1. Get your pH to 7.2 - 7.4ppm.

2. Add the chlorine. You I would recommend liquid chlorine because you'll be adding alot of calcium by using granular chlorine.

Your water may turn colors. This is normal

3. Test your water as often as possible, maybe every hour if you can, but at least once per day. You want to add enough chlorine to get to 15ppm.

4. Add your last dose of chlorine in the evening and test again in the early morning before the sun hits the pool.

The free chlorine level might be gone, or way down.

The conversion will go faster the more often you can test and get and keep your free chlorine level up to 15ppm.

5. Once you've been doing this for a few day and trying to keep the chlorine at 15ppm, test and add your chlorine in the evening.

6. Be sure to check the pressure in your filter on a regular basis and backwash. Alot of Baquacil will be coming out.

7. You can brush and/or vacuum.

8. When you test in the morning and only lose 1 ppm of chlorine, or less, it will be time for your new filter.

When you have that squared away, you can add the CYA to reach 30 ppm and keep the chlorine at 15 ppm.

Dichlor is best for raising the CYA quickly.

10ppm of chlorine added with Dichlor will raise your CYA 9ppm.

Test for Combined Chlorine (CC/chlormaines). When they are at 0.5ppm or less for two days in a row, your conversion is complete.

If you have any left over Baquacil products, try to return them for a refund or store credit.

How Do I Clear Up Baqua Floc Stuff?

by Marilyn Stephens
(Rockwood, Tennessee)

I have an inground pool I used Baqua Floc in part of my opening treatment.

I poured it in slowly through the skimmer but still got some in my pool.

I have swept and swept and swept and can not get rid of the stuff.

Is it dangerous to swim in the pool and or is there a way to get rid of that stuff?

When I sweep as soon as the sweeper touches the floc it bursts and becomes impossible to see, let alone vacuum it to waste.

Do you have an answer?

Thanks for the question Marilyn

There's not too many real pool guys (those of us who have actually taken care of, cleaned, and cleared up hundreds of pools) who are fans of Baqua products.

Here are a couple of posts I recently answered:

Switching From Baquacil To Chlorine

Swimming Pool Algae With Baquacil Use

I don't have anything personal against the products, it's just that you can do better with simple chlorine, baking soda, 20 Mule Team Borax, and pool acid.

Most flocs, algaecides, and the like, really don't live up to all the hype.

To completely get rid of a Baqua Floc, you're probably going to need to full conversion to chlorine pool.

This can be found in the first link above.

Correct me if I'm wrong, but are you using Baqua products, or is the floc just a one time deal?

Sorry to hear about your issue, but this is simply a fact of life when dealing with this kind of product.

To the best of my knowledge it is, from a biological standpoint, safe to swim in.

From a safety point of view, you never want to swim in a cloudy pool, for obvious reasons.

I would encourage you to look over the first link and seriously consider switching to a chlorine pool.

If you have a chlorine pool but this was a one time deal, you can shock the pool and back wash once per day until the pool is clear.

Here are the chlorine and shock charts you need for your size pool:

Pink Ribbon Algae

by Mary

Just opened my pool and a re-occuring algae is showing up. I have been told it is pink/red ribbon algae, it is slimmy and truly disgusting. My ph is fine, chlorine is minimal cuz just opened. Need to lower the alkalinity and raise the hardness. The Cya needs to be raised also. What else can I do???? We have an above ground pool with about 13,000 gal of water. HELP!!!!

Thanks for the question Mary

First, I'd like to have your complete chemical readings, the actual numbers:

Chlorine, CYA (cyanuric acid/stabilizer), pH, Alkalinity, Calcium Hardness, and Metals (iron and copper) and names of any algaecides you may have used along with clarifiers, phosphate removers, and/or flocs. It makes troubleshooting much easier and the process of clearing up your pool will go much faster. Green water is a symptom of the problem, not the problem itself. I also need the kind of filter you have and if it's working properly. If it's not working it must be fixed in order to clear up the pool.

You probably have a very easy and cost effective solution but unfortunately I can't do much until I have the actual chemical numbers.

If you feel your situation is more complex than this, I do phone consultations. It makes things go much faster and many people have found it extremely beneficial, saving them time and money in the long run. All your questions will be answered. I have nothing to sell you so you know I'm not bias.
