Thanks linen, I wont be home for the next week and my father will take care of the pool under my instructions, I hope it stays relatively well. I wont be able to read/reply or try anything new in the meantime. I'll post back with any news when I'm back.

Thank you, I''ll give it a look!

Horner Express does not ship to individuals, and that link to novatech is quite promising; I'll talk to them. My main concern is customs, since they've turned very restrictive lately, and I don't want a $150 packaged to be kept on hold or confiscated and kept in hot warehouses (it's summer...

The label said 90 (grams) Cl per liter of product, so I'm not sure about it's concentration. But I've seen similar pools been given the same treatment with almost no algae in them. Unfortunately, yes; but for all the winter months (june-september) and up until a month ago I had been using...

I need to get 3 weeks into the past in order to assess that "wild guess" of 100 ppm CYA levels. The pool had turned green since we hadn't been home for two weeks; and an adjusted pH together with a first shock dosage of 6 gallons of liquid chlorine killed all the algae and left the pool milky...

Test strips with a top measurement of 10 ppm being more strongly coloured than that plus a diluted OTO test; I know it's not very accurate but at least I'msure it was over 10 ppm.

If I get the time, I might as well give it a try. I might need a new OTO reagent, though. I just want to let you know that I'm always emailing salespeople to see if I can get one proper test kit shipped here, but they're classified as HAZ-MAT whch makes it really hard. I kind of suspect that...

I have yet this question, what can cause the water to cloud up when people get in for about 2 hours? No sediments on the bottom whatsoever. pH OK and chlorine was high (around 15 ppm I think).

Noted, no table salt. I've just brushed it.

Thanks for your response audone! I'm sure that dichlor does not settle at the bottom nor does it cloud the pool. I have no idea what my CH level is, but do you think it's to blame? I don't regularly add clarifiers, just flocculants (then vacuum to waste) when I'm out of options (quite often...

Ok so today the water was crystal clear, with about 1.2 pounds of dichlor added the night before, and it received 5 swimmers for about 2 hours, and now it's cloudy again. Not THAT cloudy but noticeably cloudy. pH is about 7.3 and I have just added 0.7 pounds of dichlor to combat the...

The pool was drained two years ago; but it gets about 2-3 inches of fresh water each week because we vacuum to waste. No rainy season, regular use of floaters, have been using liquid chlorine since December but have just turned to dichlor powder. I believe that with the amount of water I replace...

I think it might be a chemical problem too. The thing is, I do regularly add chlorine and the test kit always shows at least 3 ppm of TC; but since I don't really know the CYA levels, it apparently is not enough to kill everything in the pool. I really feel like I'm working in the dark because...

I'll give it a try, but I've never ever really saw any other test kits. Plus, I don't even know if they'd be in good condition at all. Every year when I try to look for a solution I stumble across this problem and don't get much help online. Anything I can do/try? Could there STILL be any...

There are pool stores, but all sell the same stuff. Online distributors have issues shipping the kits because they are considered "hazardous materials" and our customs are also REALLY restrictive on what kind of stuff you can get in.

I did add DE a couple of times; only once did it leave the water crystal clear. All other times it caused pressure to increase too much too quickly so that the flowrate reduced too much to be effective.

I'm in Argentina and it's quite impossible to find/import any test kit but the basic pH + Total Chlorine test kit. I only got some strips from a trip and I think they're not accurate at all. I forgot to mention that I have 2 pucks of trichlor in a floater at all times. Two days ago, when I...

Hi, this is my very first post. Note: I'm in the middle of summer where I live The problem: Cloudy pool water (drain cover is barely visible). Test results: pH: 7.4 Total Chlorine: 15 The thing is, I can't get a proper test kit since they don't sell those in my country. I'm not even sure...
