    Taylor or tf100 test kit availability in Australia?

    You guys are not alone. Me being in Indonesia has trouble importing Taylor FAS-DPD too and all the other goodies. I once asked http://www.hach.com/ local Indonesia rep and they said no stock as those kits have shelf life. They only have DPD and not FAS-DPD as I recalled. Also the will charge...

    Hydraulics 101 - Have you lost your head?

    Hi Mark, If 7 divers hang out for 4 hours, clarity drop a bit, usual. No one is complaining, its just me being so used to see maximum achieveable clarity and I want to keep it that way always, and fast. That is why the trolley pump ( 2nd pump ) with 20 micron cartridge and 1 micron slime bag...

    Hydraulics 101 - Have you lost your head?

    Now the 2 HP is 12 hours per turnover, too slow to maintain best water clarity when divers use the pool. Hence I have back up 1.5 HP pump on trolley and use it with the 2 HP to get near 4 hrs turnover after each pool used by swimmers or divers. Sanitation distribution concern and being addicted...

    Hydraulics 101 - Have you lost your head?

    Hi Jason, OK, I will check with my amps meter and see what I am consuming now against nameplate. I am only after faster turnover, this pump is 24/7 and only stop when bearing or impeller start needing overhaul. I am now getting so much performance loss by having less turnover per day since the...

    Hydraulics 101 - Have you lost your head?

    Hi All, Long time no write. I just want to add some info to this excellent thread. Those from countries with 50Hz ( mainly Asian and Europe ) electric supply please request proper pump curve based on 50HZ. Most US brands like Hayward and Pentair will show 60HZ pump model and they run faster...

    Now, how fresh is fresh water ?

    Hi Gang, After waiting for months and months, the Water Lab did not want ( ignored is a better word ) to do the test as per Chem Geek spec. So I got sick of waiting and unfortunate natural disaster of flooding took place 17 - 22 Jan 2013 in Jakarta-Indonesia. My pool got flooded. I will...

    Now, how fresh is fresh water ?

    OK CHEM, I will translate your calculation and ask the lab. The lab I was told is a research lab and they should be able to breakdown to the needs you mentioned. My friend has ion-exchange, but that if for his raw water to his pool and not treatment for the pool. His city water and ground water...

    Now, how fresh is fresh water ?

    Hi Chem, My friend's pool is 100% same as mine in the chemicals, though his supplier is different. Liquid chlorine for daily use Tablets, which I honestly do not know it is Tri or Di, for CYA maintenance only. NO brand on packaging. HCL for PH. Now if I need to do specific water test, what...

    Now, how fresh is fresh water ?

    Hi Guys, Once I decided to use SWG or ozone and due to my 28 - 30C water temperature, I was looking at approx 4000 PPM salt to be effective if SGW is the choice. So what I did was made water sample of 500, 1000, 1500, 2000, 2500, 3000, 3500 and 4000 PPM salt. I assemble my family members and...

    1 hour pool turnover and moving water - possible ?

    Chief, I forgot to tell you. Drains on pool bottom is not effective to get dirt based on suction alone for a wide area pool. Overflow is effective to get the top dirty water direct to gutter, yes. I clean my pool with scuba tanks, vacuum hose on left hand and a brush on my right hand once in a...

    1 hour pool turnover and moving water - possible ?

    Hi Chief, DE is what I never tried. Its hard to buy the maintenance stuff in my country for DE. I asked before and I don't like making "cakes" on the drain from DE, one complaint I heard.......is that true ? I can go water treatment route with 1 micron cartridge filters. I will take a look at...

    1 hour pool turnover and moving water - possible ?

    Hi Chem, My boss pool will be 20 meters most likely and 4.5 meters wide. If say I do side to side water flow, based on 14 pumps ( to get that 1 hr turnover ) wont there be more potential of old water mixing with new one ?. I mean pushing 20 meter wide water against 4.5 meters wide, won't...

    1 hour pool turnover and moving water - possible ?

    Hi Chem & Neil, Yes, something like endless pool but not that fast waterflow. This is not about swimming practice, this is about getting best clarity fast. US$$20,000 for extra 14 pumps and cartridge filters and plumbing is nothing compare to the overall pool cost and pleasure of needing only 2...

    1 hour pool turnover and moving water - possible ?

    Hi Chem, Yes that data looks Dang good. I needed 11x turnover with no bather load, just ambient airborne dust , to get back my maximum clarity during my 50% water change. This is the exact reason I was doing some day dreaming if moving water the way I imagined, will make a 2x turnover my dream...
