Ok, I opened late this year and had a green swamp. No worries I have done this before with great success thanks to TFP. So I checked CYA which was @ 40, checked PH 7.2 (which is where my water tends to be when I open) and of course no FC. Started the slam, it took 7 days to clear it up because I...

So I decided to buy a new pump but the big question, which one, my plan is to also buy a SWCG as well with this pump and in the future solar heat and/or heat pump or gas heater. My old pump is a single speed, 1 HP (with a 1.1 SF, I think) Hayward SP 2607X10 and the filter is a Hayward S244T, 300...

Last year I had problems with algae bloom when using a solar cover. So in trying to figure out why I bought a 50 PPM standard CYA solution so I could use it as a reference for knowing what a positive test looked like when testing my CYA (thinking my CYA level too high for my FC target). It did...

This is my second year managing an inherited old pool that needs a lot of updating. Thanks to all that give of their time on this website I have been able to quickly clean it up and use it and when I make mistakes can easily bring it back to crystal clear. I monitor the chlorine level at least 2...

We have a problem with bees being attracted to our pool, especially when solar cover is on. We saw some home remedies online such as spraying vinegar or soapy water. But what will vinegar do to solar cover and pool chemistry, and soapy water in the pool does not seem to be good either. Any other...

Just bought a Dolphin Active 30i pool cleaner. I read the directions and it says do not use in chlorine levels higher than 4ppm. This means I can only have a CYA level of 30 and can not be used during a slam. I have not seen anything about this during my research before buying. Does anyone use...

My normal pressure after backwash is 14#, when I hit 17-18 pounds I usually backwash, however since I finished start up SLAM I have only Backwashed 1 other time in about 8 weeks (during slam backwashed frequently because of all the muck). So I hit 17#, during backwash and rinse pressure down to...

I thought I had it all figured out but just went out to double check what I thought was a 20' x 40' pool is actually a 21'4' x 40' 3" pool. If I get a 20' x 40' Solar Cover how will it work on my pool? Will the wind pick up edges on the width as it could be 16" away from side, how significant...

A couple of weeks ago I found a post about ways to dispense chlorine or acid out of larger containers, there was a link to a site that had a vent built into the spigot. I can not seem to find the thread again. I have searched the site again today and found this link...

Now the stain is gone but water is very, very cloudy and no matter what I do cannot get it clear for the past 3+ weeks. Went to pool store today and this is my readings: - - - Updated - - - did I do it?

I am new to this and have only done about 10 CYA tests in my life starting about 2 weeks ago. However I am getting some huge swings in the level, I started out low, added CYA as per poolmath shot up to 40. I was happy and was going to use trichlor and when it got to 60 (I was hoping end of...

I have bought 12.5 % liquid chlorine. If I dilute it myself with water to 6%, will it be the same half life as store bought 6%?

I am new and this maybe a silly question but here goes. Has anyone tried to convert a tablet chlorinator to a liquid dispenser. When I had a garden I used a device to add fertilizer to a sprinkler system using a venture tube and regulation of orifice to dispense correct amount. I have a Hayward...

Bought a house that has a pool was told the liner had only one season but then a few seasons of disuse and cover was not put on until at least 1 winter without cover. Yes, what a mess, well to make a long story short after an expensive 2 weeks I think I am ready to start the slamming process...
