I need to test our groundwater again, but if I remember correctly when I filled 3 years ago it was 800ppm. This is common in the desert. I may just bite the bullet and go with calsaway or aqualabz' ecoklear method. I did find calsaway's patent online. It appears they're using a modified lime...

Is it true that sodium carbonate will force calcium carbonate to precipitate out and allow it to be vacuumed out? I'm also seeing something called sodium hexametaphosphate which is said to reduce calcium hardness.

My CH is 2500ppm after 3 years of evaporation in AZ and after using calcium hypochlorite for the majority of my chlorination. The rest of my levels are proper, it's the CH that's throwing off my saturation index massively. It's also causing scaling. I need to get the stuff OUT! I've done some...

I have never had even a small amount of sand come out of my filter when backwashing, did you replace the sand recently? Did you buy the right sized sand?

A friend just tried to buy one from D i c k's and apparently they no longer sell them :( The link provided in a reply above goes to a generic search error on their site. FYI

Thanks everyone, given the smoking price at d i c k's sporting goods I'm going to forgo the light for my 4th of July party and let cost consciousness win out over the gotta have it factor. -Tom

I had a solar water heater from the 80's, recently replaced with an energy efficient all electric. I have a huge solar collector on my roof. Any ideas on converting it into a pool heater? IE pump water in, monitor temp in collector (I would have to install new thermometer or temp sensitive...

Ok so I dilly dallied and now I'm hoping I can find a pool supply store than can get a GlowBuoy in my hands by Thu July 3rd to zip 85202. All the pool places I've checked online don't expedite or guarantee or have upwards of 2 days order processing time. Haven't been successful finding one...

Richard, or other chem knowledgeable folks. I did read a case online last night where an individual was pre-dissolving cal hypo for multiple hours before pouring the liquid into the pool and leaving any white residue in the pre-dissolve container. Wondering what this white residue is...

Thanks guys. While I do like the BBB concept very much and would like to strictly use bleach, obtaining and storing bleach to use as my primary chlorination method is a bit of a task. I have my water tested twice a month and I will keep an eye on the CH levels and do some mitigation as they...

Just wanted to post my most recent water results as well. FC 3 PH 7.9 CH 250 CYA 40 TDS 1800 Phos 200

Richard, Thanks for your response. I will have a look at the tabs next time I visit the pool store, I am certain it was 99% but did not look at the chemical makeup. The CH at $1.35 is a special price due to a 20% discount coupon on chemicals right now, the 100# bucket is usually $168.00 which I...

Paint the white rim? I personally wouldn't use SS in a saltwater environment. You may even be able to dye the white rim with a black fabric dye? Depends on the porosity and type of plastic.

You put them in your wall returns and it's supposed to circulate the water much better and cut pump run time by 1/3. Anyone using them? Do they really work? The concept is interesting, akin to in ground cleaning systems.

I am trying to determine a single chlorination method that I can use this summer and which one is most cost effective yet also the simplest method. 6% bleach, $1.30 gal (will require weekly bleach runs, suppose I should factor in my time and cost of gasoline to purchase). 73% calcium...
