Anyone ever use something like this: http://secure.sciencecompany.com/HM-Digital-Waterproof-pH-Meter-PH-200-P16347C679.aspx for testing their water? Appears simple, fast and accurate, but wondering if the scientist/geek side of me is coming out too much when considering something like that...

We have a heat pump in line with our returns, after our filter. When I closed recently of course I blew the return lines out, and I assumed that plus opening the drain plug should have taken care of the heat pump as well. Well, the drain plug on the heater is a sort of springy, retained drain...

I tried to blow my lines with our shop-vac this year and failed to get that to work. Next step was to try a compressor. I'd been wanting an upgrade to my dinky little $50 compressor for other reasons anyway, but didn't want a behemoth, so ideally I wanted something that would work for the...

We've had our (first) pool for 2 seasons now. It came with a "Ray-Vac" cleaner that I guess gets the job done, but we aren't exactly thrilled with either. We haven't done too much research yet, but some quick looks revealed these things aren't cheap! That led me to wonder... Does anyone know...

So, I tried using a 5hp/12gal (RIDGID) "shop vac" to blow the lines and it isn't cutting it. Based on lots of reading here I was expecting to possibly have trouble with the MDs, but I can't seem to clear much of anything!?? So I wanted to check here and make sure I'm not being stooopid...

I have 3 "normal" returns (just straight pipe through the plaster) and another "return" for the automatic vac./cleaner. I have rubber plugs that fit the 3, but the vac return has a twist lock type connection to it, and doesn't appear that it would accept any of the plugs I have. Do I treat it...

Just curious what everyone does with their completed tests - I mean, these reagents have all kinds of hazard warnings and so on, so how do you dispose of yours?

First, a little background: I'm in my 2nd full season of owning a pool, and, until very recently, was not using BBB. To maintain a clear/clean pool, I was using pucks for chlorine, MA for lowering ph (never needed to raise), and Sodium Hydrogen Carbonate to increase TA (never needed to lower)...

Anyone know if anti-freeze goes "bad", opened and/or factory sealed?

Looking around online for winterizing stuff (antifreeze, poly60, etc.) for my first attempt at pool closing (builder closed 1st year, and we paid em the 2nd) I stumbled across this: http://www.intheswim.com/shopping/produ ... word=E9NAC It claims to be a non-chlorine based oxidizer but doesn't...
