I'm considering adding a propane heater.

Thank you for your reply. I haven't added any significant amount of new water to our pool in three years. I also have not tested the well water we would fill with for those levels (pH, TA and CH). We have a mesh cover so snow and rain get added to the pool throughout the winter. I'm...

Hello, I have been using TFP and TF Test Kits for three seasons. This is our fourth year with a pool and my fourth year using the TFP Process for balancing our water. I am in the midst of SLAMming since opening the pool last Saturday, May 16th. Here are my current levels: FC: 13 CC: 0 TC: 13...

Hello, Here are my test results from this evening after concluding a SLAM (passed OCLT this morning): FC: 8.5 CC: 0 pH: 7 (I think) CH: 100 TA: 80 CYA: 60 pH test result I interpret as 7: I added 5lbs. of soda ash per the pool calculator (mixed it as a slurry and poured into pool in several...

Following this forum and getting some helpful replies to some questions I went from this: to this: Thank you!

Attached, please find two photos of the diving board bolt pattern for our inground vinyl pool. I bought this home a few months ago and there was no diving board in place. Looking to replace it. The measurement from the bolt nearest the pool to the edge of the pool is 30". The distance from the...

CA92807, When you say you use your speedstir for 30 seconds and then wait several minutes for the trapped air bubbles to dissipate - what is several minutes? Three to five? More? Also, do you use the CYA measuring bottle with the red cap to measure out your pool water and R-0013 or do you...

I have been trying "calibrate" my eyes to read the CYA test so I ordered the R-7065 Sample Solution from TF Test Kits. I went out this morning with my TF-100 and R-7065 to get a photo result of the CYA reading of 50. I added R-7065 to the bottom of the CYA testing bottle label and filled the...

Thank you Texas Splash and duraleigh. Should I mess with the pH to get from 7/7.1 to 7.2 before initiating the SLAM? I have a DE filter with multiport - if I can't stay home until the weekend, would you suggest beginning the SLAM and just set the multiport to recirculate in order to avoid...

My questions are: Help me interpret this pH test (7.1? 7.2? lower?) Test Results for today: CYA: 30-45 TA: 6th drop turned and kept it red so is it 50 or 60? CH: 5th drop turned blue so is it 100 or 125? TC: 0 Am I ready to plan and begin my SLAM? Should I have enough liquid chlorine on hand...

UPDATE: Initial goal of reducing CYA - drained and refilled 50%-60% of the pool (see attached photos). Drained to just below the pool light and refilled with well water. New test results are as follows. CYA: 30-50 (overcast conditions - will retest in better lighting) FC: 0 pH: 6.8 (please see...

Hello, I am in the process of doing partial drains and refills on my pool with high CYA (between 90-100). This is a green swamp I am preparing to SLAM. Since I am waiting for my pool to refill, I was boning up on how to be best prepared to SLAM. I read a few things here and there about the...

Tore down filter again after backwashing and rinsing. Replaced manifold and remaining broken grids. Tried to install replacement O-Ring for bulkhead only to find it's 1/4" too large - why is this? I looked up the correct part number in the Pentair FNS manual and ordered Torx replacement O-Ring...

Hello, I began opening my pool for the first time after a 3 year hibernation. We purchased a home this spring including an 18' x 36' vinyl liner pool (~26,700 gallons), which has been closed for the past two winters. So, I removed the cover this past weekend; unplugged both skimmers and inlets...

Hello, I'm a new homeowner inheriting an inground vinyl pool (18' x 35'). I have a Pentair FNS Plus 60 DE Filter, a Pentair Challenger High Performance 1 hp Pump and Hayward skimmer controls/valves. Also, I believe I have an Olympic chlorinator. The 18 year old mesh Loop-Loc cover is shot and...

Hello, I am buying a home with an inground vinyl liner pool. Through the home inspection process I had the pool company that serviced the pool come out to inspect it. The pool has not been opened in what will be three years this coming spring. The vinyl liner was replaced three years ago...
