    Cleaning cylinders and spoons

    Hi, I've been meaning to ask this for a long time, but always forget. My TF100 chlorine only cylinder and blue spoon have become very discoloured with a black residue. It makes it very hard to see what colour the sample is. Whats the best way to clean it off? I've read somewhere that muriatic...

    CYA sock split

    Hi I have recently opened my pool. CYA was low, so added the requisite 250g dry stabiliser to bring it up to ~30/35. But, now the sock that it’s in has split and I have a nice pile of dry stabiliser on the pool floor. The powder is too light for my vacuum to suck up. Is this likely to...

    Hot Tub Filter Run Time

    Sorry for the n00b questions. We live in the UK! We need it to be relatively warm before venturing outside! There is a filter button on the control panel as well as the bubbles / heat controls. I was just confused as to why it was there if it runs every time the heater is on. Do you need...

    Hot Tub Filter Run Time

    Hi, My brother has just bought an Intex inflatable pureSpa. 795 litres. As the family “pool guy”, he asked me how long he should run the filter for. It’s a cartridge filter. I checked the manual and it does not mention an optimum running time, only to clean the filter every few weeks...

    Cannot raise FC above 12 whilst trying to SLAM

    As my pool is vinyl, I don't think the increased CH should be much of an issue? I measured it last month (for good measure) and it was 80.

    Cannot raise FC above 12 whilst trying to SLAM

    Just because I haven't got any more bleach (well, enough to add another 2 or 3 litres), and tomorrow is Sunday. The earliest I'd get a delivery is Monday or Tuesday, so don't want all this to be wasted effort

    Cannot raise FC above 12 whilst trying to SLAM

    Hi All, I returned from a weeks vacation today to a green swamp, so began slamming straight away. pH was 7.5 FC was 0 (I added bleach and a 200g trichlor puck before going away to keep things ticking over, but clearly wasn't enough!!! doh) CYA was 40 when I tested before my holiday I've...

    Chlorine conundrum

    Hi Steve, yeah I'm aware of the SLAM process, and know that Chlorine will get consumed quickly. This could almost have been a pre-emptive SLAM. There was virtually no algae, just the mere beginnings, so i was trying to stop it before it got a hold. Thats what I found odd, that such a small...

    Chlorine conundrum

    Hi I've got a bit of a conundrum for you all. Here are my latest set of test results: FC: 4 CC: 0 pH: 7.5 TA: 80 CH: 60 CYA: 35-40 I noticed some algae creeping up the sides of the vinyl, so i open Pool Math app and tap the SLAM button. My SLAM level is 16, and the app says add 2.1 litres...

    Different CYA readings at each end of the pool

    It was probably about two weeks ago when I added some dichlor. The pump runs a good few hours every day and people have been swimming a lot so I guess it’s pretty well mixed. Ive always struggled with the CYA. This is my first year using bleach. Before and for the last 10 years I used trichlor...

    Different CYA readings at each end of the pool

    Hi I know the CYA test is a particularly difficult / subjective test, but I am getting conflicting / confusing results. My pool doesn't have deep or shallow ends and so I always tend to test in the middle. But because of the week of hot weather we're having (Google it - Manchester is hot for...

    My pump has died. Can anyone tell me which to buy?

    Pool stores are non existent. We don’t have the weather for pool stores. Ill happily buy online. There are loads of retailers for pool stuff. I guess i just need to understand the maths and relationship between pool volume / pump flow rate / kw power / horsepower etc :) for example why are...

    My pump has died. Can anyone tell me which to buy?

    Hi My pump has died. It had a good life - 12 years old. It's no longer manufactured, but I don't know of an equivalent... Here are the numbers from the top cover... Can anyone tell me what they mean? What do I need to know to buy a replacement? I'm guessing X horsepower and Y kW...
