Hi all, I have had a Pentair Kreepy Krauly Prowler 820 that has worked well for 5 years. Last night we had a lightning storm that I think zapped the robot. It gets power but does nothing. I was looking at the Prowler 920 as a replacement. Recommendations? If

Occasionally we all need to add some CYA. Curious if people do what I do...buy 3” inch trichlor pucks and add those until I get back to the desired CYA level. I figure I’m killing two birds w one stone (CYA and chlorine) and it’s nice taking a break from adding liquid chlorine for a few...

The past 6 weeks I have had to put 2gallons of 10% bleach in the pool every day to maintain FC. I do not have any CC and have run the OCLT several times just to see if I might have algae, I don’t. Water looks great so I am happy with the outcome but 14gallons of bleach every week is getting a...

I have a Pentair Kreepy Krawly Prowler 820 and I noticed it not moving today when I turned it on. Turns out the impeller is broken... the blades look sheared off. Anyone have this happen to you? I have no clue what could cause this, maybe a rock? I tried bending the fins to see if brittle...

I have been following TFP practices for a while and still learning. Gotta question: excluding OCLT tests, when you add bleach say daily in the summertime as required to keep FC in recommended range, do you add in morning or night? And does it matter? I ask bcos I am a morning person and...

Has anyone here made a pool chemistry flowchart based upon the TFP methods? I think a flowchart with some notes could be very useful to people new to pool chemistry. Myself and wife are both technically minded so TFP is easy to understand, but trying to explain or teach to non-tech folks can...

I typically use 10% bleach for pool chlorine. Following Hurricane Harvey in my area in 2017 I stocked up on maybe 30lbs of granular shock and it had been sitting there for 7 months or so. I let the pool chemistry get away from me a little and had some algae growing in say 30% of the pool. I...

I swam in the pool this weekend for the first time this season. Swimming with brush in hand to get those hard to reach places [emoji3]. I noticed on the steps in one area I had maybe 20 copper colored stains the size of peas from fertilizer. The brush did nothing to remove the stains. Does...

My white pvc pool piping is above ground at the equipment (duh) and is in full sun all day in the Houston TX area. Does anyone recommend painting the piping or valves for UV protection? I thought I read somewhere pvc can become brittle over time due to UV exposure. Has anyone done this...

I just added 54lbs of calcium chloride as needed post Hurricane Harvey in the Houston area. I was desperate and bought it from that pool store that will not be named (rhymes with stresslies) and it cost me an arm-and-a-leg. I know don't say it, but I was desperate. Where do y'all buy Cal...

Hurricane Harvey is headed toward the Houston gulf coast area. I wonder how much chlorine I'm going to have to add to the pool after 12-30" of rain over the next few days. I'm guessing a bunch!

There is a "show signature"?

I had family over yesterday and the pool was sparkling and right on w chemistry. However, we decided to hop in the spa and several people mentioned a "smell" which I am guessing was chloramines (have not checked CC yet but I will). My question is: I am thinking my spa chemistry is off and I...

Before someone decides to be a wise guy, I am aware it is called "Wall Whale" and not "Wall and Floor Whale" [emoji12] The WW works great on walls as advertised but it does not transition well to floor. The angle of the brush causes the plastic nosing to hit the floor on the down stroke and it...

Been following advice on TFP for some time, but curious how often you test free chlorine and cyanuric acid levels? Of course there are times that require more frequent testing such as when water chemistry is off or large rain event or large swimming party, etc... I am asking specifically...

I have Calcium build up along the water line (tiles and stone) in my 3yr old pool. I have tried using a brush and pumice stone but it does not come off reasonably easy. I read about using a soda blaster to remove CA buildup. I already have a large vertical tank air compressor my questions...

I have a variable speed Pentair Intelliflo pump and I run it 24hrs/day, 7days/week. Other than the cost of electricity, are there any downsides to this approach? I run it at about 2/3 max. speed.

Hi all, I brush my pool weekly but I get algae buildup in the nook-n-crannies along steps, ledges and at the radius of wall/floor. Is this common or should good water chemistry prevent ALL algae from forming? Also, do you just go swimming with a brush to get the hard to reach places? That's...

I had my IG pool installed in the Spring of 2013. After about a month of use, we noticed calcium deposits on the slide and notified the pool builder. The first response was "calcium happens". The calcium buildup got worse within a 2nd month of use and I notified the pool builder. He did not...
