Oh, my God. I removed the plaster because of a paint issue! Thanks for the information.

I initially had planned to continue using the pool after the repair. I'm in El Salvador, so the cost of the work will be a fraction of what it would be in the U.S. The problem was that I took the advice of my gardener (less expensive in this country, as well, but more expensive in the end as I...

I have an in-ground pool at a house I've been renting for a number of years. I drained it a few years ago and began a process of re-surfacing and re-painting it. A few years prior, I had drained and re-painted it. Perhaps due to an excessive use of chemicals, I noticed some cloudiness in the...

I've searched on the internet but couldn't find an answer to this question. How many pounds of 70% granular Cal-Hypo would be needed to equal the chlorine in 5 gallons of 5% liquid bleach?

I have a "Pentair Clean and Clear Cartridge Filter". (I don't know why it's called a "filter" instead of a "pump" or "cartridge filter pump". That's the word used in the Owners Manual.) In the manual, there is this WARNING. Everything is in capital letters, due to it being a warning, so I'll...

Would shocking the pool eliminate this black algae - without the need for brushing? I know that pools should be brushed regularly, but am curious to know if shocking will completely dissolve this algae adhering to the walls and floor.

You're contradicting yourself, aren't you? In the earlier post, you stated "Chlorine levels do not cause irritation, pH levels do..." Then you say that it is a myth that smarting eyes are "usually" caused by pH out of range. Then, finally, you say the main culprit is for the most part pH...

Regarding burning/stinging sensation around the eyes, could combined chlorine cause this? I don't know what the pH of combined chlorine is, but is the issue high or low pH, or either?

Re: Clorox Vs Cheap brand of bleach I should have it by Tuesday. I'm sort of baffled as to why one application of bleach rapidly eliminated the green algae, but not the black. Maybe because the black is more firmly adhered to the walls and the floor? The green could be moved by slightly...

This brings up a point that concerns me since using non-Clorox household bleach in my pool. I'm in Latin America, so the choice is pretty much off-brand bleach. After adding a gallon one night recently, the following day some swimmers reported a burning sensation or stinging in the eyes. I...

Re: 1 gallon of muriatic acid and 2 pounds of trichlor per w How about if I just use bleach without the MA? If the CYA levels are high, then there shouldn't be a concern about losing the effectiveness of the chlorine after 30 minutes under the sun. MA is a very strong acid, isn't it? If one...

The person taking care of my in-ground pool claims to have been using one gallon of muriatic acid and two pounds of trichlor per week. I thought that he had said that he was using an algaecide, as well. But he said no. [I'm in El Salvador. He speaks Spanish. Me, not so much.] A few weeks...
