While I do not have an in-ground pool, I have looked after one and currently have an above ground pool. To close it, I elevate the chlorine levels to about 10 ppm, adjust the pH levels to between 7.2 - 7.6 and cover the pool with a solid opaque and leak-proof cover; All I get in my pool over...

I have a 1.5 HP pump and I would like to know if anyone has had any problems with pump seals if they were adding chemicals through their pool skimmer. I have added CYA to my pool through the pool skimmer according to the directions and on occasion, liquid chlorine. The reason I ask is that the...

Most what you are wanting to do sounds fine to me, just some cautionary notes and suggestions. If you are using a cover that is of the tarp or poly type and does not transmit light into the pool, then all you need is to raise the chlorine levels and balance the pH of the pool water; if your...

It depends on the type of cover you have, if it is a "tarp" or polymer cover that is does not transmit light into the pool, then just adjust the pool pH (7.2 - 7.6) and raise the chlorine to about 15 - 20 ppm; don't need algaecide. As algae is a plant it needs light to grow; if your cover is...

Congratulations on getting your new pool, living in Florida, I am sure you will get lots of use out of it. I live in Southern Canada my pool got lots of use this summer. I have currently a 15-foot round above ground pool and previously owned an 18 foot above ground round pool. My pool season...

In all the time that I have had an above ground pool, I have only used liquid chlorine added to my pool in small amounts each day or as one daily addition using automation. I add stabilizer (CYA) according to the rate recommended in the spring (May) and boost it in mid-season (July). I also...

Excellent breakdown about the costs, but I have one more aspect that probably is as important as the cost, that is the danger of solid chlorine forms. All pose a fire hazard due to their oxidizing properties and the list of warnings for Tri/Dichlor from the EPA is lengthy. Solid forms also...

If you are getting a new cover, get one that is light and water proof and made of strong polymer material, they may cost more, but their worth it. My cover has a pro-rated warranty for 20 years. It works great, keeps my pool clean over the winter and reduces the amounts of chemicals that I...

Hi, I also live in Southern Ontario, but have an above ground pool. When I close my pool I raise the chlorine levels with liquid chlorine, about 6 L of 6% per ~20,000 L of water. During the year I have added CA and copper based algaecide as well and more recently, since my water is alkaline...

I don't know what type of cover you have, but if it lets any light in, then this is why you may get algae growth. An light proof cover prevents algae growth and maintains your chemicals in the pool water longer. I have an light-proof water tight cover on my above-ground pool and it keeps my...

Thanks for the information, I have an above ground pool 15 foot round and it takes me on my own about 2 hours to close it. All I do is a light vacuum, drop the water levels, about 6 inches below the skimmer and return, put a plug in the return, pad my in pool light, add a little liquid chlorine...

I have kept liquid chlorine over the winter in my shed, if kept in the dark and close, it can be frozen and will retain its potency or only lose a little of its potency. If you let it freeze in a plastic carboy, just make sure there is enough room for expansion of the frozen container to avoid...

I am looking for a dedicated timer to operate a 24 volt AC solenoid operated valve to add liquid chlorine to my swimming pool. The timer must have a minimum increment of 1 min and a maximum increment of up to 60 min. and the potential to activate the valve up to 4 times per day on all days...

I know of someone who has tried the Metchlor Chlorinator on their in-ground heated pool in combination with a copper/silver ion generator and were pleased with it. I took a look at the system and found out the following; the timer supplied has a battery back-up on it, there was no problem...
