I'm just curious as to people's experience and/or opinion. My Pentair Quad 100 DE filter's original cartridge filters (which I dutifully cleaned each winter) were at the end of their life cycle, and dealing with DE disposal here is a pain. So I decided to change out the filter cartridges for...

I haven't yet been able to find another good installer (mine disappeared shortly after the original build in 2015), so since I am somewhat technically inclined I took on all of the maintenance from the beginning and want to do some updates to our simple system. Currently I have 1.5" plumbing to...

My question is, can I increase flow back to a pool water feature by increasing pipe size from 1.5 to 2" on the pool pad outlet side only and not changing anything else? Our pool was originally plumbed all 1.5" with a 18" Sheer Descent, stair jets, return jets and with a Pentair Superflo VST it...

I'm looking to see if my symptoms fit with a typical scenario before I call in the pool guy (who around here will try to sell me a new heater). Pentair Mastertemp 250 (Canada), installed 2015, the older un-connected control board and 5 button panel. SWG DE inground Pool. Has worked pretty...

I just wanted to check in with those in the know before I replace my Intellichlor IC20 (Installed Spring 2016, Manufactured 11/12/2015. Rev: 3050) - worked great until now, maybe a little less effective towards end of last season and beginning of this was working in May, beginning of June and...

For the past 6 Canadian Winters, we never pumped out some water from our pool (apart from lowering the level for the closing. It always seems to fill up again (from snow and rain), but for some reason (that we don’t know) it never overflows onto the coping. Is there a reason for this? Is there...

I am having a contractor re-do the polymeric sand in our pool deck, but the original pool contractor (who did both but is now long gone) used polymeric sand between the coping stones (essentially really large heavy coloured paving stones by techo bloc, the blocks have a purposeful consistent gap...

We live near Toronto, Ontario so the winters are mild by Canadian standards, but still a deep freeze and lots of precipitation (mix of rain and snow). Every year when closing I lower the water level below the returns, and we have a safety mesh cover. The few years we’ve been getting more...

I've had an issue with sticky CMP (Custom Colded Products) Spa Master Top Draw Air Controls (Gray 1") before, but now one is so stuck that trying to loosen it is also loosening the locking nut behind the fibreglass stairs it's attached to. So I am lookng for possible ideas for removing this Air...

Title says it all. I am curious to know what the purpose of the 24 Hour SWG Chlorine Output setting in the Pool Math App does?

Perhaps this is a "talk me out of it" but I have a simple Pentair pool system with one skimmer, one waterfall, one gas heater, Quad-DE100 (means I only have to backwash or clean it when closing each year), Intelliclor-20, Aqualamp Rainbow Rays LED Pool Lights (x2 on same circuit) and two stair...

For the previous two years I used Borax and Muriatic Acid with what seemed like relatively accurate LaMotte Borate Test strips. Water sparkled and softer, pH more stable, level around 50ppm to start - definitely pleased. Second spring the level was down to around 30ppm (and I brought it up...
