I purchased an active 20 earlier this season and I absolutely love everything about it except for the cord. It is supposed to have a swivel cord, but it doesn't seem to swivel as easily as I was expecting, and have been noticing more and more tangles throughout the summer. I am very careful to...

Hi Everyone, We have a one year old pool with 3 Hayward Colorlogic lights that were working perfectly until tonight. Now the two outer lights won't light leaving only the middle one working. We tried to resync, factory reset, and flip the breaker and nothing helped. Any ideas before I call our...

Hello, I have read a number of high ph threads and everyone's situation always seems a little unique. I am constantly fighting to keep my ph down, adding dry acid frequently and watching it climb back up to the high end of the scale over 8.0. I am testing with the tf-100 kit, TA is at 100, and...

After reading almost all 90 pages of the s200 owners thread I am just about ready to order. Now that Dolphin has the $25 rebate I am going to go with dolphin over the pentair warrior but I am getting frustrated deciding between the s200 and active 20. Everyone says there is no difference but...

Can anyone explain the basket modification for the dolphin s200? I have seen mentions of it all over but can’t find exactly what it is/does or if it is necessary or just personal preference. Thanks, about to pull the trigger soon.

We had our new inground vinyl pool installed late last year and had the builders close it as part of our contract. I am happy we did it because it seemed important to get the winterizing done properly to avoid damage. I am thinking about opening it myself though because it seems like there is...

Is there any code or trick to getting the best price from Marina? I don't know if I was expecting too much but I was a little disappointed in the prices I was given, they were essentially the same as Amazon.

I am really struggling to keep my FC in the recommended range. I test the water in the evening when the sun is off the pool and add what the pool math app recommends to get me to a FC of 7, the high side of the range for my cya of 40. The last 2-3 days when I test in the evening I am below the...

Thanks everyone for your help, it is really valuable as I learn my way around our new pool equipment. Today I clearly did something wrong but have no idea what... We had 2 big storms this weekend and my water level rose above the skimmer so there were a bunch of floaters on the pool. I thought...

Our vs pump is on a timer so we don’t mess with it much. Should we shut it during a thunderstorm or when we leave the house?

We had our concrete deck poured yesterday and therefore could not test the water or add bleach while it was setting. The night before I added what I thought would be two days worth of bleach but when I checked it tonight the FC was all the way down to .5, well below the minimum of 3 for my cya...

Our concrete pool deck was just poured yesterday, we got good weather to keep it dry and it’s looking good. We are staying off it today to let it cure and can walk on it tomorrow. Will splashing and dripping chlorinated pool water on the new surface affect it in any way? I know some water can...

Sorry for the double post, originally put this in the wrong section. Our new pool has had water in it for about a week. Testing often, slowly increasing the cya, and going through about a gallon of 10% each day. Cya is about 40, so every night after the sun is off the pool I add enough to get...

We have a new inground pool, less than 36 hours old. Our variable speed pump seems to be losing prime as the water level in the pump strainer gets noticeably lower throughout the day. We mentioned it to our pool builder and he said the variable speed pumps run differently and aren’t always...

We have a brand new 18x36 inground, filled with water last night. This morning I tested fc and it was 0 as expected and I added 96oz of 10% walmart liquid chlorine to get me to 3. CYA was also 0 and I put 4 pounds of leslies powdered stabilizer in a stocking and it has been dissolving all day in...

Hi everyone... We are about two weeks away from starting our new inground construction and still haven't picked a liner. We have it down to two choices, both by Matrix Pools: Twilight Sundance and Rialto Blue Diffusion. We originally wanted Twilight Sundance but are now backing off thinking it...

First time opening after using bleach last year and the water is crystal clear. Thanks to everyone here for such great info. Tested the water after starting the pump and the numbers look perfect but with my wife 8 months pregnant I wanted to double check and get some feedback to make sure...

So I have ordered a wanda the whale for my AGP. Although I like the robotic vacuuming idea, I also think it will help with water circulation to let it roam around for a few hours every few days. We have an oval pool with only one return jet, and I think we have a few dead spots that wanda can...

According to the charts with a cya level of 60, my min FC is 5 and target FC is 7. Is there any reason not to run it on the high side? Maybe consider 7 as the minimum and try to keep it floating between 9 and 12? The cost should be the same to bump it up a few points whether it is from 5 to 8...

Wow I am terrible at reading this test. I saw a post in another thread that you are supposed to let the solution "settle" for at least a minute, but it was an old sign. Should I be letting the solution settle inside the view tube with the tf-100 kit? I can actually see the suspending particles...

Hello all, new to the forum and looking for help. Have been fighting a small algae issue since the end of last season. Crystal clear water but greenish patches appear on the bottom and walls. Not slimy, more dustlike and forms greenish tinted clouds when brushed. At first we thought it was...
