Pool Stabilizer Won't Dissolve

by Helen Cook
(Industry, Texas)

What is the best way to add the stabilizer? The granules will not disolve in the pool if I add them directly to the water.

I've tried disolving it in a small bucket - but still is does not dissolve.

I have a vinyl above-ground pool and the manufacturer says that the the undisolved chemicals should not come in contact with the pool liner.

Can I put it in the filter? It's a cartridge type filter.

Thanks for the question Helen

There are two ways to go. First, you can use Dichlor chlorine. This is a stabilized form of chlorine that adds both CYA and chlorine.

Be careful when using Dichlor as it can get out of hand quickly. For every 10ppm of chlorine added with Dichlor, you'll raise the CYA by 9ppm. For every 10ppm of chlorine added with Trichlor tabs you'll raise the CYA by 6ppm.

Get your CYA to 30 - 35ppm, then use liquid chlorine for weekly maintenance. I like Dichlor for the reasons above. You're hitting the pool from both sides, chlorine and stabilizer.

Next, you can, very slowly, add the stabilizer into the skimmer. You'll want to dilute it in a bucket, then pour it into the skimmer.

If you go to fast it can harm the pleats of the filter.

You're correct in not allowing chemicals to settle to the bottom of the liner. This can cause staining and bleaching.

Zinc Anodes For A Swimming Pool

by Donald

What should be the makeup of anodes be for a pool system? % of copper, silver and zinc?

I am looking to source the rods in Ireland without having to import from UK but I need to know what the makeup should be.

Thank you


Thanks for your question Donald

My personal experience with anodes is limited, but this is what I do know. First, do you have a salt water pool that you're concerned about? Many times salt water pool owners want to avoid any costly replacements or repairs due to the salt water corroding the metals in the pool.

Some may say that sacrificial zinc anodes for saltwater pools are a must, but there's much of debate on this. There doesn't seem to be much reliable information about how well they work on salt pools, just that people sell them. By reliable I mean independent research.

I know that putting an anode in a plastic skimmer basket is pretty useless.

The anodic process and protection is an electrical process. This means that you need to establish the right electrical pathways or the zinc won't work. It's a pretty complex subject without many clear answers or solutions.

Sacrificial anodes are a protection against early sings of eroding metal. They will go first, then the metal in the pool.

In my opinion, sacrificial anodes are not needed for pools that are in proper order. Perhaps for older pools that are not bonded well, a sacrificial anode might be good, but it's not the best solution. Good water maintenance is the best prevention.

Here are some good sites to look over:




As for the % of zinc and copper, I would advise calling the manufacturer and talking to them. I hope the above information will point you in the right direction.

Best of luck and let me know how it turns out for you.
