Hi In Australia we get the el cheapo Pentair ECO-CHLOR this has a clear poly carbonate housing the electrode plates , mine after 3 months of use has gone opaque . At first I thought it was calcium build up but when I removed it the plates and the surface of the housing was free of scale , i...

Ok just googled it . That's what happens when you assume you know something . The chemistry actually makes more sense now . Thanks for making me think chemgeek I think I will just go with a normal salt system . Salt is cheap .

Actually I am not sure not that the chlorine is lower than a normal salt pool , what AIS says is that it works with a lower TDS for a typical 3500ppm to 2500ppm , salt pools being aprox 5000 ppm . the anode is titanium maybe the cathode it copper not sure . So basically replacing sodium salts...

Hi Milan , Did you go with the mineral chlor system , I was at the pool shop today as this system was suggested mainly because my mother has sensitive skin . A quick look here is my take on it : still still uses chlorine just less 1.5ppm not 3-4ppm so how does it kept the bact algae down...

Yes I was at the pool shop today talking about it and it is not a govt legislated requirement just advised , I can plumb it with not much trouble I just wold be introducing more 90 deg elbow than I would like . Also now I mention the the pool shop guy that I was going salt for the better feel...

Hi Page 7 http://www.watermaid.com/media/pdf/product-support/WATERMAID-WM40-Owners-Handbook.pdf and page 5 http://www.astralpool.com.au/sites/default/files/products/manuals/Viron%20Chlorinator%20Instructions.pdf . maybe it is a thing here in Australia all the pool shops I have gone to so...

Thanks malcolmb5325 yes I have seen the plumbing for the cells , that's when I realized the cells had to be higher than the filter .

Hi all So i want to go salt pool is 6K gallons = 18000L , what are the benefit or cons of these systems that have PH and FC sensors , I like the idea but in reality it just seems more tech to maintain ( calibration the sensor ect ) and expensive if it fails . I am now thinking that just a...

Ok thanks Chem Geek well I should be ok then , it just seemed logical that if there is a gas trap it would trap air expunged from the panels , but I also realized many people must have it set up this way so it must work .

Hi guys So I have decided to go SWG and just found out I need a gas trap where the cell sits higher than the filter . My first concern is that the flow of the intelliflo VF 30GPM will be to low to move the Hydrogen gas from the cell I have seen reports on whirlpool forums where a low flow...

Yes I have moved the VRV plus increasing the downstream pressure by just using the deep return . I think I just have to be happy with 25gpm and your there obviously is not that much pressure at the lower rpm range and that's what you need to avoid is over a pressurized solar system . Thanks...

Hi Mark , The VRV problem seems solved by moving it closer to the pump , its on the wall leading to the roof and just using the one deep return increasing the pressure downstream . The problem is that the VF External control feature only lets you set gpm not rpm so the only way is to keep...

after some reading Marks Hydraulics 101 and pumped 101 I think this is whats going on . As this speed rpm of the pumps impeller slows the head produced by the pump is reduced , this from pumped101 " Head varies as the square of a change in rotational speed or impeller diameter (peripheral...

So more theories as the pump rpm drops to 900rpm the pressure at the deep return aprox 4.5ft so 2.2psi? becomes greater than what the pump is producing causing the deadheading? .

Ok if i run with all three returns open the pump runs at 20gpm 895rpm but the there is nothing coming out of the deep return , when I try to ajust the flow to give more to the deep return the system shut down . it seem the problem is on the return side .

well I took out the spring ran at 25gpm 1205watts , I then set the Ext control to 20gpm when the solar turns on the VF gives a system blocked ! alarm then primes then settles to 950-960rpm 160watts it will run like this for 5mins then give the system blocked ! alarm , the manual says this will...

I notice when the pump is running at low speed the flapper is almost closed , maybe this is stopping the pump ? Tommorow I will take out the spring .

Ok as I thought , so for some reason the pump once primed and running at 20gpm shuts off thinking there is a blockage maybe the check valve .

So panel area is 41.67ftsq X 3 panels = 125ftsq X 0.1gpm X 12.5gpm . I set the VF for 20gpm for solar this morning and it ran ok for 15mins no bubbles , then the VF gave a system blocked message then restarted . It has been running at 25gpm for an hour now no problems . I wonder if the check...

http://www.troublefreepool.com/threads/9248-Solar-Panel-Technology-Comparisons chem Geek suggests here a flow of 4-5 gpm per panel generally . my panels hold 3.32gal including header per panel , So I should be aiming for 15gpm for the whole system ? . It all comes down to the VRV staying close...

It all worked out well , I have only just wired it up and it all works fine relay and second valve wise . thanks to Jerryt Iam running solar at 27gpm and may get it a bit lower as the specs for the panels for optimum heat exchange say 4-5gpm per panel , there are three panels . I may even...

Hi just an update, Well finally got round to installing the second valve actuator and relay on the two shallow returns and moved the VRV down where it use to be nearer the filter . The system runs at 27gpm with no air getting in , i am lowering it 1gpm to see how low I can get . At 27gpm...

Hey well tried my reduced eyeballs and it did help send more water to the deep return . But have having the VRV on the wall caused it to when draining sort of shudder I think becuase its not drianing thru the supply side the VRV stays closed till the vucuum effect is enough to drag some air up...

Found some old old eyeballs and an electrical fitting and MacGyvered them together test them tomorrow with the lower VRV .

Depending how deep it goes make sure the bottle does not crush with the pressure . Very interesting idea .

Eyeballs yes those are what I have been eyeballing but but I can not find the for sale in Australia . you would not believe the limited range of everything here before the net we didn't know but . I will try moving the VRV and see if it closes and drians ok . but I will still have the issue of...
