I have a mineral cartridge that fits in my SWG unit. I don’t replace it because it’s expensive and I think I remember folks here don’t think they are necessary. I saw a video where a guy put copper plumbing fittings in his skimmer. Copper and silver are what are in my mineral cartridge. So...

Hi, I’ve been developing “tear drops” of something running down my walls below the water line and very white spots on the floor. Any idea what these are? Thanks, Doug

Hi, I get calcium scale around the pool and especially below my sheer descents. Using a pumice stone for removal is time consuming and doesn’t usually get it all. Plus, getting in and out of the grout lines is really difficult and removes grout. Is a mix of muriatic acid and water safe to...

What’s the best accurate test to get for testing salt levels?

Hi, I keep my pool supplies inside and was wondering about Muriatic acid. I was wanting to start keeping that outside by my pool equipment. It is in a plastic bottle. It would be exposed to the outside elements including quite a bit of sun. Will this degrade the acid? Thanks, Doug

I have a Raypak 406A pool heater. I had the front cover off to install a new flame roll-out switch. I turned the heater on and it fired up and the wind blew it out. I went to turn it back on and nothing...…..not even the display is working. It's dead. I did turn all the power off and still...

This year (#6 pool year), I notice areas that looks like tears running down the wall. They are the color of the quartz aggregate finish and about an inch long. Any idea what this is? All my testing is in range.

Hello, Starting my 5th year. I’m opening the pool next week. What I have been doing the in the past is shocking the pool with “super pool treat” from the local pool supply company and pouring in a bottle of algaecide. Is there something else I can use here? Thanks, Doug

Hi, I’ve had my pool closed by the company who had built my pool for 5 years now. They use the Cyclone Liner Vac to blow out the lines. It works great, but it’s expensive (about $300). Are there any less expensive options for blowing lines or is this the way to go? Thanks, Doug

Hi, My Polaris 360 is on its fifth year. It just isn’t doing the job like it used to. Every years gets a little worse. Here are some issues: 1) The swivel part on the actual unit where the hose connects to is always pointing forward. This piece is an elbow and is supposed to point to the...

Hi, What’s the best way to get rid of white build up on tile? It is bad on my raised bond beam and just underneath my sheer descents. Thanks, Doug P.S. - How do you upload pictures from an iPhone??

Hello, I had to drain my pool for a repair. It is a SWG pool. It is now filled back up from my public water supply. What steps do I take to balance everything? Also, do I need to add magic jacks or algaecide? Thanks, Doug

Hi, I have a rust spot that has just shown up on a wall on my four year old pool. It's within the size of a quarter. It is either the metal ties used to hold the rebar together or one of the rebar ribs. I want to cover this up. What do you suggest? Thanks, Doug

Hello, My wife just ordered 3 Windmill Palm Trees that she wants by our gunite shell pool. I'm concerned with damage to the shell at some point. They are 3' tall now, but I have read they can get to 30' tall and I wonder about root damage to the pool shell. Any input here? Thanks, Doug

Hello, I bought the Taylor Salt Water tester because my SWG is on the fritz. I tested yesterday and it read about 3,600. Today, I had the PB come to check my SWG and he used my tester to check the level and he got 3,000 and we tested twice. I just went and tested and I got 3,600. I'm getting...

Hello, Just opened the pool the other day. The salinity on my jandy aqua pure sensor is reading 2.1. I've already dumped a bag of salt in and it is not moving at all. The sensor is new and was put in last august. This is the kind that has a program A and B. I am running program A. Any...

Hi, I have a Nature2 Fusion Soft. I noticed the other day that I was very low on chlorine.....about .6 ppm. I jacked up the SWG to 100%. I tested today and I have 0 ppm chlorine. I then noticed today I have "No Flow" showing on the display......which I learned chlorine production stops. I...

Hi, I have a stamped concrete pool deck. It will be its third season here in Pennsylvania. I need to seal it this year. What ever is on there now from the builder gets slippery when wet. So, I'm first looking for a good product and hopefully is not slippery when wet. Thanks, Doug

Hello, My pool cover pump all of a sudden blows the circuit when I plug it back in. Not sure why, but I suppose I need a new one. This one is only 2 seasons old. Does anyone have a recommendation for a decent pump? The one I have now is a Rule Pool Cover Pump (1800). Thanks, Doug

Hi, Does anyone know if it is ok to use "Klean-Strip Green Safer Muriatic Acid" to lower pH? This is available at Home Depot. I know I can, but are there "fillers" in it that I'd not want in the pool? Here is the MSDS...

I've been posting the last week here and in some of those posts some folks are saying I may have algae. How do you know if you have algae?? What does it look like? Is the clarity of the water any indication?? My water is crystal clear and I can't see any signs of algae, but I don't know what...

If I want to get my FC level up, can I use bleach even though I have a SWG? This year, I'm having trouble "shocking" my pool with my SWG. This pool just started its second year. Last year, I could easily raise my level by turning my SWG to 50% production and it would take maybe 4 hours. I've...

My TA was 110 and I wanted to get it down. I have put in a total of 16 cups of baking soda....two doses at 8 cups each over two days. Yet, my alkalinity seems to be the same. Here are my readings: FC 1 CC .25 CH 320 PH 7.8 CYA 55 Pool just opened and first time this year lowering TA. Last...

Hi. My second year with my aggregate finish pool. I just opened a week ago. When I brush, I am seeing a "cloud". What is this? I never noticed this before even when the plaster was new last May. It doesn't seeem to be going away. Thanks, Doug

I am just starting my second year with a brand new pool. Chlorinated via SWG. The pool is 13,500 gallons and last year I was going through a gallon of muriatic acid per week. I've been open for 5 days now and it looks like the trend continues.....lots of muriatic acid. Is this expected...

Hi. I have a Taylor testing kit. Bought it last year and it came with Taylor brand Phenol Red. My pool store has Phenol Red, but it isn't the Taylor brand. Can I use that? If so, will I add 5 drops like my Taylor brand. Lastly, will it be compatible with the Taylor brand acid demand drops
