Our pool has an opaque thermal foam pool cover (4mm sandwich of closed cell foam) rather than a translucent bubble cover. We keep the cover on 24 hours a day except when swimming (drought and water restrictions here). I have found that if the pool doesn't get much use in a given week, the...

Accidentally left the SWG turned up, FC went up to 7.5. Following the usual TFP advice I told the whole family it was fine to swim in, however all of us came out with irritated eyes. Never had this happen before at lower FC levels, all other params are fine. FC 7.5 CC 0.2 CYA 65 PH 7.6 TA 100...

@mas985 I split this from No Chlorine Generation When Solar Heat On , as it was getting a bit off topic. When my Solar is on, I am seeing an 8 PSI increase at the filter pressure gauge (from 4 PSI to 12 PSI). I have an Intelliflo VF which is set to run at a constant 25 gpm both with solar on...

I have had the pool continuously covered for the last 2 weeks with a thermal foam cover that is completely impermeable (i.e. not a mesh cover). The cover is tight fitting edge to edge, covers 100% of the pool surface. Daytime ambient and pool temps are hovering around 50F. When doing a check...

My pool has a high level of Magnesium Chloride in the salt mix (popular in these parts with SWG for the supposed therapeutic benefits of Mg). I was wondering if this might be throwing out a couple of the Taylor tests. 1. CH is reading very high, 900ppm on a new pool with no additives other than...

Hi, My PB has setup the motorized solar 3 way valve using a 90 degree actuator instead of the normal 180 actuator. i.e. instead of the inlet being at the "bottom" of the T, it is coming in from the side. Hence the need to use a 90 actuator to switch between the outlets. Is there anything wrong...

Pentair has been advertising for years (and multiple pump versions) that the IntelliFlo runs at a 45dB noise level. Does anyone know what RPM or flow/head that noise rating is at? I couldn't find it documented anywhere, and local dealer was unable to tell me. I am aware the pump is very quiet...

Planning a mediumish size (26' x 10') pool, PB is recommending dual skimmers due to nearby trees. Was trying to get my head around how this impacts variable speed pump use, as flow rate is now split between the 2 skimmers. With dual skimmers will I have to run twice the flow rate I would...

Anyone with an AquaLink Z4 know how to interlock the cleaner booster pump with the main filter pump? The installation manual makes reference to the special "Clner/Sp3" schedulable item, and also "Cleaner Lockout" logic. But there is nothing to say how to assign that logic to a particular Aux...

Hi, Based on research on TFP and elsewhere, for new build I was planning on solar heating run by main filter pump (Intelliflo), with automation to switch 3 way valve and increase VS speed when solar is active. The catch is *every* installer has told me flat out they never install that way on a...

Hello, Planning a new 10k gal pool (36k L here in Australia). I am looking at around 300 sq ft cartridge filter (seems suitably oversized). At that size I can either get a large single cartridge filter or a small quad cartridge filter. Is there any reason to go either way? Quad cartridge seems...

The TFP CYA/FC recommendations make a lot of sense to me, but as a newbie planning my first pool I am worried that TFP recommendations appear to void many equipment warranties. For example Zodiac (Australia) has the following exclusion that applies to *all* its equipment: Maximum chlorine...

Hi, first time poster from Australia, just starting to plan and research my first ever pool. A recent fad here is companies releasing Low TDS Chlorine Generators (Some call them freshwater chlorine generators). These are standard SWG's, but with an oversized cell so they can run on very low TDS...
