    Have I damaged my robot?

    I never really got into the idea of pressure-side cleaners, I guess it seemed more complex, with booster pump and whatnot and didn't seem worth it for our relatively small and simple pool. So I just manually vacuum the debris (except this year, for some reason, I decided to see if the robot...

    Have I damaged my robot?

    Thanks, that's reassuring! I've rinsed it out with a hosepipe best I can, and I'm now getting the pool mostly clean and will put it in again afterwards, hopefully being immersed will flush it out a bit.

    Have I damaged my robot?

    Ordinarily, when opening the pool, I manually vacuum all the silt and debris to waste and get the pool clean and balanced before using the robot. It's a miserable job that takes hours, so this year I decided (because I'm an idiot, a lazy idiot) not to do the usual manual vacuuming when opening...

    Chlorine level rising

    It is, yes, there's a bubble-type cover (which is surprisingly effective at not only keeping heat in but also using solar heat gain to warm it up a bit). In a typical UK summer, we can maintain it through the season at about 24-26 deg C (75-79 F) without heating. So it's not warm, exactly, but...

    Chlorine level rising

    You're almost certainly correct. This is using a Lovibond Scuba, a cheap photometer. Unfortunately, none of those test kits is available in the UK. I found one of the Taylor kits on Amazon that would ship to the UK, but the reagents were specified as being almost out of date, and it wasn't...

    Chlorine level rising

    Reassuring, but something's still a bit weird... FC fallen to 5.4 from 5.5 after another two days; so no chlorine added at all for a week and there's been pretty much no chlorine loss. In fact it's still higher than when I stopped dosing chlorine a week ago. Admittedly, the weather here this...

    Chlorine level rising

    That's reassuring, appreciated.

    Chlorine level rising

    Exactly that! I'm using a Lovibond photometer tester and I'm not sure I would trust it 100% but it is pretty consistent (eg testing again with a fresh sample gives the same results, etc) and more accurate than test strips. I've been using it for 2 or 3 years now (with fresh test tablets each...

    Chlorine level rising

    First off, at the risk (certainty!) of incurring the wrath of the TFP, my pool is dosed with chlorine pucks rather than liquid chlorine or SWG or whatever - it's just how it's done here in Europe - particularly in older pools - and haven't generally had any issues. For the first time in a while...

    If algae and silt is vac'd to filter, will it end up back in the pool?

    Well, yes, you're absolutely correct the Lovibond Scuba doesn't read Chlorine beyond 6ppm, so no good for shock/slam accuracy. Problem is, the first of those Palintest kits mentioned is what I used before, and I found the Scuba more reliable and if course easier to read accurately; and the...

    If algae and silt is vac'd to filter, will it end up back in the pool?

    Thanks for all the excellent advice, as ever this place proves to be a great resource. Because impatience, I'd already gone ahead and added some more chlorine yesterday, latest test results as folllows: FC 2.6 TC 2.9 (so I guess CC 0.3?) pH 7.4 TA 86 CyA 19 It proved impossible to get...

    If algae and silt is vac'd to filter, will it end up back in the pool?

    Long story, but we had a "pool guy" open up this year as he was coming out here anyway and I thought it'd save me some work. It didn't. I've now got the pool clean and water clear and sparkly. After shocking, the chlorine level fell back to 2.0ppm and for a day or two I had free chlorine of...

    Ants and woodlice destroying mortar under coping

    Thanks for finding those links, much appreciated. You might well be right about the mortar; it's not what I wanted to hear though! It's less than two years since the whole thing (pool refurb, new liner, copings, paved surround) was done. Can't face the idea of taking it all up again and...

    Ants and woodlice destroying mortar under coping

    Just opened up for the second season since refurb, and although everything still looks good, I noticed a pile of ants and woodlice on the floor of the pool in one corner. Looking at that corner, it looks like they've somehow got under the copings and are emerging through a gap they've opened up...
