Hiya! Will a 2" backwash hose fit over the backwash outlet for my FNS Plus Pentair 48 DE filter? The outlet is 2" inner diameter, but once the width of the piping itself is taken into account the total diameter is about 2.25". This is the one I'm looking at...

Crisis averted! A second pool sample was completely normal: pH 7.5 and TA 80....it's a mystery.... Thanks for the advice -as usual TFP forum never lets me down. Over and out. Fiona

Hi pool lovers! We've been managing my pool with BBB for 9 months and everything's been hunky-dory until today. I test the pool once a week and pH usually rises a bit while FC drops. Add the appropriate amount of muriatic acid and bleach and it's all good. Typical previous readings: FC 3-7 CC...

Sal: I'm not sure to be honest. If so, which valve could it be and where would I find it?

Ok now this is driving me mad. Have tried all the suggested remedies and then some other ideas I had: 1. Put together tubes under water...check...still lot of air. 2. hold tubes against return jet to fill with water....check...still lot of air. 3. checked tubes for holes, found a couple of...

Re: Pool skim or Pool Devil? :: UPDATE Ok so I'm clearly useless with a tape measure...turns out or returns are smooth 1 inch PVC!! This seems highly unusual yeah? Well I bought the Pool Devil Pro and the Universal Adapter which is designed to go into a 1 1/2 inch smooth PVC pipe. And of...

hmm, will go check the fittings...

Our return line is a simple 1 1/2 inch smooth PVC pipe. What would work best for us: Pool Devil or Pool Skim? Cheers, Fiona

Hi When the pump is on with just the skimmer working the pump basket doesn't have any air in it. However when the pool cleaner is going there is a lot of air in the pump basket. I make sure to purge air from the tubing when I put it in. Could there be something wrong with it? A leak hole in the...

Hi all We've had the pool for 6 months now and I still feel like it's a bit of a mystery but I'm determined to understand this set up ****** it....! Is it possible that my main drain isn't working? There is absolutely no suction coming off it. Is this right? We have a Star-Rite U-3 skimmer...

Coolio, I'll give that a try. Another thing that might help with the diagnosis, I've been letting pH get up into the higher end (7.8) and then I bring it back to 7.4...should I be not letting it get so high and bringing it down lower? Therefore keep it between pH 7 and pH 7.5 kind of thing?

We bought the place in January and I haven't added any, but I can't say anything for the previous owners. Is there a test I can do to see if an algaecide has been added? Fiona

Ok now I'm really really confused....if Reverse Osmosis removes metals (not 100% but most according to Jason the Site Administrator)...then how can my stains be caused by metals? The RO was only done 2 months ago... Any thoughts Bruce? Cheers, Fiona

Will Reverse Osmosis remove metals? Cheers, Fiona

Ok I've tried a couple of things and are now more confused. To test for Black Algae: tried my darndest to scrape off even a tiny bit of the black stuff and I get nothing. Then left a puck on a an area overnight that had three black spots - didn't do a thing! To test for copper (metals) filled...

Ok, is it safe enough for me to jump in and try the puck test and vitamin C test with FC so high? I'm a little suspicious of the metal deposit concept because the black spots only appeared after the pool was RO'd and FC got low. Unless of course I just couldn't see them when the water was...

Hi Everyone So I think we have black algae but am not 100% sure. The brief history is that we bought the house with the pool (pool is >15 years old), water was a little cloudy, got the TF-100 test kit and discovered CH >800 and CYA was >100. Bruce and Sal did RO on the pool water and get the...

Thanks Mark. Scott: If a new motor and seal is the answer than does that mean I don't have to replace the whole pump? And who/where to I go to get this fixed? Thanks, Fiona

Hi Everyone Our pump seems really loud to us - husband unit is ready to blow a gasket himself! It is a Whispaflo 1 hp. We have solar panels on the roof of a single story house and a spa with 4 jets There's also definitely a leak at the pump. And when we turn the solar panels on ALOT of air...

Re: CYA and CH too high :: Reverse Osmosis worked! Ok so the verdict is in: Reverse Osmosis works brilliantly! Got the guys from Pool Services Technologies in and they rigged up their truck which contained the filter and reverse osmosis membranes. They even have their own generator so they're...

Stupid question: Is a SWG system compatible with a DE filter? Thanks Fiona

Hi pool people! Has anyone had reverse osmosis treatment of their pool water done and successfully reduced CYA and CH? If so, how much of a reduction was ACTUALLY achieved? Would love to hear your thoughts, both positive and negative... Cheers, Fiona

Ok then, what's the forum's thought on the reverse osmosis solution...appeals to my eco warrior hubby but does it actually work for reducing CYA? Cheers, Fiona

Ok, thanks for the advice. So I a dded a gutload of bleach this morning to bring up FC to >7...need to buy shares in Chlorox...also added muriatic acid to bring down pH to 7.4. Regarding the pool drain issue...The Husband Unit is "anti" the pool drain and fill. We're eco warriors at heart! I...

Hi everyone My husband and I have just bought our first home in San Diego with a pool. I have to tell you I'm very excited to have found this forum because I'm a scientist and love the concept of water testing and managing the pool on our own with bleach, baking soda and borax... We've been in...
