I've been slamming my pool for well over a week now, maybe 10 days. It has been passing the OCLT and CC tests for about a week now. I run my filter 24/7. The water remains cloudy with hardly any noticeable improvement in clarity from day-to-day. I am using bulk liquid chlorine, 10.5%, which...

Can someone explain how CYA impacts the effectiveness of chlorine? I understand that CYA helps preserve/protect chlorine from sunlight. How does that work? Does it combine with and protect chlorine, keeping chlorine from working as a sanitizer below a certain level, depending on the level of...

I've noticed a lot of folks have reported problems with Quikrete sand being too fine and getting into the pool. I've used Quikrete sand for the last four or so years. I recall when I initially filled the tank with sand there was a small but noticeable amount of sand that came out into the...

I have a 20' Intex AGP that I'm in process of reopening. I have a Intex sand filter which came with the pool. I let the water turn green over the winter. Two days ago I started slamming. The green went away within a few hours resulting in the water turning grey. I scooped and vacuumed the...

How much 60% polyquat to use for closing a 10,000 gal AGP in SW Georgia? I'm ordering a 32 oz container. Is 16oz enough, saving enough for the following year, or should I just pour the whole 32 oz in? Also, it appears I should wait 'till the water temp drops to 60 degrees before closing, is...

I have a 20 ft Intex AGP. I let the water go green during the winter. Two weeks ago I slammed it, easily killing the algae and passing the OCLT test by the second night. There was a lot of dead algae on the bottom and also, I assume, suspended. I've vacuumed most of it out and have been...

I have a 20', 52", above ground Intex pool with sand filter. The water has turned green over the winter. Should I drain the water and start over or should I add chlorine and work on clearing up the water that is in the pool? (I have a well) My sand filter has been in operation for about two...

Going on vacation for a week this month (July). Intex, 20' AGP. How do I "close" to prevent algae during my absence?

I have a 20', 52" Intex pool. My CYA is 40. Down here in the SW Georgia sunshine it appears I will lose roughly 2.5 ppm chlorine during the day. The chart on this site says I should maintain a FC level between 3 and 5 ppm. It appears I will need to add 32 oz of 8.25% bleach each day to keep...

I prefer to do my own testing per advise on this forum. There are many benefits to that and I'll summarize some of them. (1) I have confidence my results are accurate. (2) I don't have to drive to the pool store. (3) I don't have to endure the store clerk trying to sell me expensive chemicals...

Tips on this site are saving me $$$ in many ways. Here's a good one: For the FAS-DPD Chlorine Test I have been using the 25 ml sample size with my K-2006 kit. The 10 ml sample size is mentioned in the instructions as an alternative but the 25 ml sample size is featured more prominently in the...

How critical is circulation to accurate chlorine and ph testing? In other words, if my pump ran for four hours yesterday afternoon may I go ahead and take water samples and test for chlorine and ph this morning or should I turn on the pump for 30 minutes or so prior to taking my water samples?

I recently replaced my Intex AGP with another one due to the support beams rusting out presumably because of the salt water (not using SWG on new pool). A skimmer did not come with the new pool so I had to adapt the old skimmer to work with the new one. To start with, I had to purchase a new...

Here is a summary of some of the things I've learned in a short time on this site: 1 - Algae got a foothold and multiplied quickly because I did not check and maintain the recommended FC level often enough (in relation to the CYA level), allowing it to drop too low before boosting it back up...

I have the K-2006 kit for which I need to replenish a few of the reagents. Would there be any monetary advantage to ordering a TF100 kit or, at this point, just replenish the supplies as needed (in larger sizes than came with the kit)?

A clerk at the local pool supply store asked me what I was using for chlorine in my AGP. I told him I was using regular Clorox bleach. He acted shocked and told me that was not good, because it would add metals and other undesirable contaminants to my water. Is there any truth to this or was...

I have a 20' AGP which holds roughly 8,600 gal. I'm using chlorine. This is my first season with this pool and using chlorine after having to replace a similar pool which I was using a SWG which rusted out the support beams after three seasons of use. Cut to the chase: I am attempting to use...

I just bought a 50lb bag of Quikrete pool sand from Home Depot for $5.48. I am using it in an Intex sand filter. I assume it will work ok. Has anyone here had good/bad experience with this product?

I'm new to this thread. I just replaced a 20' Intex pool which I have used for three seasons. The metal beams had rusted through in multiple places. I am quite certain it is because I was using a SWG system. I won't make that mistake again with this type pool. My new pool is also a 20'...
