Covered except when swimming, so often that can be only an hour or 2 each day it's uncovered. But that doesn't seem to be enough, needs that good 24-48 hours of continuously uncovered to prevent or fix the hazy white. Definite chloramine smell whenever the cover comes off. It makes sense that...

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...

Retested pH with Taylor and palintest, both agree around 7.5 - 7.6. Salt levels are fine (around 3300ppm using taylor). I will do an OCLT tonight, but I am wondering if this is a case where I should just go ahead and SLAM even thou there are no indicators for it. Is that a bad idea?

Tested using lab calibrated palintest photometer, high chlorine model (accurate up to FC 10). EDIT: Just checked FC and CC with Taylor, and confirms the photometer results. FC dropped to 2.5 prior to this. I understand you are implying CC may be the culprit, but if levels are < 0.5 then that...

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...

The message is getting confused again here. This is not about running solar at a different speed (which any solar controller can do). This is about running solar at *two* different speeds. One speed to prime solar, then a second different speed to hold the solar at once it's primed. Afaik none...

I have been doing the bucket test with cover off pool, and after a 5 day period there is about a 1/4 inch difference. However the pool surface is exposed to different water currents, sunlight and wind conditions to the water in the bucket. So I'm thinking that may account for the difference? I...

The VRV can be in many locations, even just above the equipment pad. All it has to do is allow air in when under negative pressure so water can drain when the system is off. If it is functioning correctly and sealing (which mine is), the location has no impact on the performance of the system...

Water has to exit from the highest point, otherwise the panels don't fill unless you run them at a very high flow rate. I wonder if adding a constriction to the return pipe is an option? Yes it would increase tdh, but i guess the hope is by letting the panels prime at a lower flow rate, it is...

OK unfortunately my Easytouch and Intelliflo do not have that option of setting a higher solar prime speed. Other than added tdh, Is there an issue with just running the panels without full prime at their rated flow speed? In my case running at rated flow without prime still uses much less...

Managed to test some things. First of all I removed the VRV completely, and this made no difference at all to the pressure or bubbles in the returns. So its definitely not a VRV issue. Then I tried starting at panel rated flow speed, run for 30 minutes, then increase speed a little, wait 30...

I have an Intelliflo and it definitely doesn't reprime when speed switches, hence my issue with solar prime. I was thinking one solution may be to run a short scheduled program each morning after the main pump schedule is running. Just run 5 minutes at high speed with solar valve open, then...

I think the original question got lost here, I am curious because I have the same question. The goal is to have a solar priming speed that is different to the solar run speed. I.e: - when solar first switches on, run at speed X for 5 minutes to make sure the panels are primed. - after this...

Regarding the superflo, it can run on 110v I thought, so I don't quite follow what the issue is with power supply at your equipment pad? In terms of automation, yes you need to wire to mains and then use a low voltage cable to wire the pump to low voltage relays in the easytouch. Each pump...
