    SLAM Criteria Disagreement

    Well, you know where it's going: 1) if you have a larger pool, SLAM chlorine gets expensive. 2) 2021: many (most all in my area) stores are sold out of 'pool chlorine' (liquid & tablets!). As you can see in the threads, we are regularly going ~10 days, just waiting for the water to clear...

    I need your help. Cloudiness has not changed over a week & a half !

    Hey experts! I'm sure you can figure this out. I have run out of ideas, & nearly patience. I took the mesh cover off my pool on May 25. I vacuumed, then adjusted the pH from way high down to 7.1 & TA from ~40 up to 80. I may have overshot CYA from ~20 up to ~70 (perhaps more on that in a...

    new K-1000/K-1001 both reading very high vs TF-100 FAS/DPD

    This is my 6th season with this pool. Previously, the K-1000 & K-1001 very closely matched the results from the TF-100 DPD powder test (& AquaCheck strips). My pool has been quite stable for years, so I traditionally only do the DPD powder test weekly. This year, both the K-1000 & K-1001 are...

    Hello. I figure if it is stainless steel, I can/should just strip it & leave it unpainted. So, how do I know whether it is stainless? If it is not, what is your advice for repair? How to strip? How to paint so it lasts? The pic with the exposed...

    actual pool frog !?!

    Hello. I really don't know where to post this. I've had a few dead frogs in the skimmers over the years, which I assume is normal. Now, I have a frog which appears to love the chlorine. So, get him out of there, right? Problem is, I now have hardly any insects in the pool (or even skimmers)...

    replace Hayward Super Pump with Super Pump VS ?

    Hello. My 2HP Super Pump (SP2615X20) has started making a loud screeching noise. I would like to have a multi-speed pump. It looks to me like the Hayward Super Pump VS (SP2600VSP) motor/impeller would slide right in to the hot/box/basket, so that I don't have to jack with any of the plumbing...

    sudden noisy pump - pressure/air problem ?!?

    Hello. I think I need some fairly urgent help here. I just bought this house, with pool, this Spring. The [uphill] pump has been OK, I think (21psi) . Yesterday, I noticed my pump (Hayward super pump - 2hp, 1.0sf) is 'screaming' much louder than usual. So, I turn it off, & it sounds/appears to...
