I cleaned my filter grids yesterday. I felt like I had an excessive amount of DE in the filter, even after multiple backwashes prior to opening it up. When getting ready to refill, I was looking at the sticker on the side of the filter and realized it says to use 4.8 lbs of DE (for my 48 SF...

I have a cheapo inflatable hot tub. Have been outta town and a buddy came by while I was gone to put some chlorinating liquid in. Tested water today, and results were strange. Chlorine showed fuchsia/purple and never went clear. PH was purple and acid demand reagent changed it to blue. TA was...

I replaced the motor (century motor B2854) on my Whisperflo pool pump (Schematic). I bought a new seal kit, and replaced items 11, 16, and 9. On 11 and 9 I used some lubricant when installing. On 16, I put some silicone around the side that goes into the seal plate, and nothing around the side...

Moved from here. I found this when searching for a similar issue. I just bought a house with a pool, and the CYA is high so I'm trying to drain/refill. I thought I had shut off the skimmers, and was pumping my water to waste, but then I heard the pump sucking air. Sure enough, after re-filling...

I put a new scumbug in recently after a partial water swap and filter change, and it turned yellow. The only chemicals I've put in since the water swap (about 100 gallons on a 400ish gallon hot tub) have been dichlor and muriatic acid. Anybody ever hear of something like this? I only swapped...

I've seen this formula for water replacement interval (WRI) in some old posts multiple times by chem geek: WRI (days) = (2/9) x (Spa Size in Gallons) / (person-hours per day) Each time he says this is for the dichlor-then-bleach method with NO ozonator. I never see where he or anyone else says...

I recently moved to Houston, and I bought a hot tub a couple of weeks ago for these cold winters and mild summers :p Anyway, I've had two other houses with two different pools, and have used the TFP method without a hitch. So far, everything is going fine with my spa (water is clear as can be)...

I read this by JasonLion in the Borates sticky: "Borates inhibit algae growth, improve the feel and appearance of the water, buffer PH, and reduce chlorine consumption. The reduction in chlorine demand varies from pool to pool. Borates prevent algae from getting started, so you don't use up...

This could be long--sorry in advance. I had a new pool installed last year, and I decided to go with a variable speed pump since it was for one reason or another free for me to upgrade to it. The pump itself is a Viron P280 variable speed pump with speed settings ranging from 1375 RPM to 3075...

Hello All, I think I've tracked my issue down, but I thought I'd post to see if anybody has any pointers or other thoughts before I go to the trouble of tearing this unit apart. My pool heater is one year old, and it worked fine last year. I tried to start it up after uncovering my pool...

I just got back from vacation last night. I had a guy that was supposed to be adding bleach to my pool and emptying the skimmers, and well, he didn't. I'd also mentioned to my neighbor (different guy) that if he gets a chance he might swing by and pull leaves since they're coming down so...

So I have a new pool this year, and it is my second pool to maintain with the TFP method, or BBB (and of course muriatic acid). My previous pool in Texas had a DE filter. It always got the job done. My new pool has a sand filter, and I have sometimes questioned whether or not the thing even...

Hello All! I'm going through a pool build right now in Tennessee (we are ALMOST finished), and the weather just hasn't cooperated since the build started in JANUARY! We've had an abnormal amount of snow and rain, but recently after a lot of other small issues, my liner has been installed, the...

I'm asking this on behalf of a friend that came to me with something that happened to him yesterday. He went swimming in his community pool in his neighborhood for the first time this year, and when he got home he had water in his ear. He got out some Hydrogen Peroxide (as he has done many times...

I cleaned my filter grids yesterday, and everything went pretty smoothly. One grid had a tear in it so I had to go buy a new one, but other than that, everything appears to be fine. This morning, I went out to check on the filter, and it looks like there MAY be a small leak where the clamp bolt...

My CYA is around 45-50 so my suggested FC value is 6 with a minimum of 4. Has anybody seen a noticeable difference in the amount of chlorine used if you keep your chlorine above the suggested level? I'm wondering if I put my chlorine up around 10 if my pool would use MORE chlorine, or if it...

I see there's a place holder for a borate test here. I was just wondering (since I just did my first borate test using LaMotte's strips) what color the strips should be when they come out of the bottle. Mine appear to be a somewhat pinkish color already (probably between 30 and 50 on the scale)...

I did the OCLT last night just to make sure there wasn't something in my pool that I can't see (the pool is only a few weeks old to me as I just bought this house). I had taken the chlorine up to shock levels for my CYA (CYA = 45-50), and when I measured it last night it was at 17 (down from 20...

I just moved into a house and it has a pool. I've been around pools all my life, but I've also never lived in Texas so I think there are some new things I have to learn. I'm new to these boards, so I'll take any advice anyone can give me. I just did my first test with a new Taylor K-2006 test...
