Hello, We’re new homeowners and the home came with an above ground pool. I’m at the point where the equipment is set up and I’ve just started vacuuming. We have a hayward perflex ec40 DE filter and attached pump. The previous owners had a terrible cover on the pool that basically disintegrated...

Hello, Recently, I decided to take a look inside the balance tank to clean it and inspect the auto valve and everything else. I performed the following activities: Remove all water inside (using pool pump and later using a wet vacuum) Apply pressure water (with a pressure jet) to all walls...

I was in process of cleaning the filter tank assembly and decided to get to a side problem of the filter having a small leak while the pump/filter is running. Got to removing the manifold and center rod to attempt to get to lower o'ring since the o'rings do eventually get old. Anyone have any...

I am a new pool Owner and keep solving problems one at a time as I bought this house with an older pool. This form has been incredibly helpful. Just when I thought that there was nothing else to address, we had a big rain. There are probably 100 earth worms in the bottom of the pool. Is this...

I am so glad I found this page! I just bought a house with a pool last year. I'm going through a whole different issue besides this, but am deep in pool school and plan to start SLAMing this pool next week if all goes well. I have a Harris 24" sand filter and back washed it last week. The back...

We have a brand new pool with a very dark blue plaster color. The plaster had streaks and discoloration so our builder did an acid wash with Muratic acid. The plaster color looks amazing, but there is now a fine, milky dust that I can’t seem to get out. We put in some super floc to get the dust...

After several failed attempts to clean my waterline with a pumice stone as well as acid, I found a succesful method using Bar Keepers Friend. This requires lowering your waterline a few inches. I used Bar Keepers Friend and water to make small batches of paste. I slathered the paste on about...

My dad's house has fallen into decrepitude the last several years since he's had more and more trouble moving around. The backyard especially has grown into an awful state. The old in-ground pool in particular is one of the large hurdles I'm trying to leap. It's a concrete pool that is 4ft deep...

Happy Friday everyone! I know many of us are fans of using skimmer socks and I needed to replenish myself for the season. I just scored a nice deal on Amazon for a 12 pack for $9 bucks. Same brand I usually purchase but on sale. They’ll last all season for sure. Anyway, I thought I’d share. Have...

So not my pool but im at a loss of how to help. Friend bought an above ground 20' dia x 4' intex pool. The pumps were replaced due to total lack of power to a 3/4 hp one with a sand filter. We keep doing our best to test and treat his pool water but he keeps having dirt building up on the...

Since getting the house, I have had a large stain in the bottom of my gunite pool. It is large and kind of cloud shaped and dark brown. The stain has not changed size or color over the years except where I have attempted to treat said stain. Previous owners did not do a good job of maintaining...

We are in the design process for our pool & cabana and we currently have a contemporary rectangle style in-ground pool. I had my designer leave a gap in the middle of the stairs off the sun shelf to allow for a wall that would allow for me to swim laps in the pool. My designer said he has...

New Pool Owner and Active 30 owner here. After powerwashing the cement around the pool, the pool was quite dirty. I had the Dolphin run about 3 or 4 cycles (with the filter ending up with a small amount of sand in it after every cleaning) and the pool still looked like the below with dirt along...

We purchased a used 1-year old Intex Ultra XTR rectangular pool from someone who couldn't keep up with the maintenance under his trees. We are first time pool owners and we have used TFP as our primary source for all our site prep and future chemical undertakings. The problem is there is some...
