    Liquid Chlorine Feeder?

    I moved to an HOA a year ago and am helping to maintain an indoor and outdoor pool here. The indoor pool has a bromine feeder plus a large tank that feeds acid to keep the pool water balanced. An Aquasol Controller is used to set the sanitzer level and the pH level and it all works really...

    Pool Heating Costs?

    Kind of an unusual question and I'm not sure there is a good answer, but thought I'd ask anyway. We had a significant increase in the cost of gas and suspect that heating our pool might be the issue. The 60k pool was being maintained at 87-88 degrees. We have since turned it down to 82...

    Was wondering if anyone has found an effective prevention solution for that scum that builds up on pool tiles. I am helping to maintain a condominium pool and cleaning the tile with a tile cleaner and scrub pad has become an almost daily chore. The tile on the side where the skimmers are...

    Best method for cleaning tile?

    I have used super tile and vinyl cleaner (In The Swim) with a stiff brush to clean scum build-up on the tile. However, I used almost a full quart to do the job and this job needs to be done about once per week. Has anyone had success with a product that will prevent this build-up? If not, is...

    We are looking for a pool cleaner for our condo pools. We have both an indoor and outdoor pool. I called Marina Pools and Spas and was told they were out of the Wave 60 model. Margaret recommended the Explorer E70... said it was as good as a commercial pool cleaner. Anyone have experience...

    Is there any reason to backwash a DE filter if the pressure has not risen by 5-10 psi? Is it okay to go several months between backwashes if the filter pressure is not rising.

    Bad Solenoid?

    We have a Controller that controls the flow of bromine and acid to our indoor pool. Has been working well to keep snaitizer and pH at appropriate levels.

    Shocking a Bromine Pool

    I am helping to maintain a condo pool and have some questions about shocking the pool. The Pool company currently shocks the pool every two weeks during their maintenance visit. They use a product called Wipeout (MPS?). Is it okay to continue to use this product or would liquid chlorine be...

    Starting to see some algae in indoor bromine pool

    I have recently noticed small amounts of algae at the bottom of an indoor bromine pool. This is an association pool which I help to maintain. The pool company says they add algaecide, clarifier, phosphate remover and shock weekly. They shock the pool using potassium monopersulfate. All these...

    Lower pH or leave alone?

    I will close my pool on Sunday for the season. Recent tests show all levels within appropriate ranges. With pH of 7.8 and water temp of 55, I get a CSI of -.17. As water temp drops, Pool Math shows that CSI also drops. If I lower pH to 7.6, CSI drops even more. Should I just leave the pH...

    Safety Cover Recommendation

    Looking for a new Meyco Saftey Cover for a 25' x 50' pool. What should I expect to pay for just the cover? Any thoughts on solid vs. mesh covers.... pros and cons? I'm assuming a solid cover would keep the pool cleaner, but would have to continuously pump water off of the cover, whereas mesh...

    Safe to Swim?

    If there is a chlorine residual in the pool (and little combined chlorine.... less than .5) is it safe to be in the water if algae is present in the pool? I know the algae should be addressed by SLAMming, brushing, vacuuming, etc. Just wondering if people should stay out of a pool where some...

    pH at Closing

    Will be closing in a week or two. Noticed that pH has been rising lately… currently around 8. However, I also noticed that as water temp drops the Pool Math calculation for CSI also goes down. So… should I just leave pH at the current level and not adjust? CSI currently at .17 with pH at 8 and...

    Pool Cleaner Recommendation

    Suddenly Seeing Sediment

    Haven't noticed this in my pool until recently. There is a fine sediment that I see gathering in the bottom of the pool. Apparently it is getting through the automatic cleaner and the sand filter. This looks a little like what you get when you use a floc in your pool, but not quite as bad...

    Conversion Costs/ Potential Benefits

    What should I expect to pay to convert my 20,000 gal pool to salt water? I painted my pool this year with epoxy paint and usually get 4-5 years before it needs to be redone. Should I expect any longer life on the paint job if I install a salt water generator? Thanks.

    Pool Math Online Calculator vs Pool Math App

    I noticed there is a slight difference in calculating CSI values when I use the online Pool Math calculator as compared to the Pool Math App. If I enter the same readings, they produce a .08 difference in CSI (.05 vs. -.03). Why is there a difference and which is the more accurate? Thanks.

    Currently, my TA is on the high side at 110, but my CH is on the low side at 250. Along with my other readings (pH @ 7.6, CYA @ 40) my CSI is at -.02 (with water temperature of 65 F). How important is it for me to bring my TA and CH into the ideal range if my CSI is good? If I lower my TA to...
