    SWCG self install, acid injection question

    While I'm here, another newbie to SWCG question regarding the Autochlor. It is supposed to have a socket outlet, 240v, to run the pump so you can't have a SWGC on pump off scenario (I guess) . My unit came with a fancy cover over a blanking plate :( so I'll need to wire up my own. I suppose...

    SWCG self install, acid injection question

    Hi Costas, Sorry about the delay, been swimming... and hiding from the CEO... Whilst I agree with the idea of putting the acid in last in theory, I read elswhere on TFP ( can't remember exact posts) that acid before the cells is beneficial because it keeps the plates clean, and aren't they...

    SWCG self install, acid injection question

    Sorry about the long delay in responding, the chief executive around here (wife) keeps on slotting new items into the ' to do ' list above the SWCG installation project... resistance is futile... Anyway I have solved the Autochlor cell orientation problem by taking a cell to bits and...

    SWCG self install, acid injection question

    Thanks for replies. I have solved the sulphuric/muriatic acid problem, the Italian pump manufacturer has got a retro fit viton tube and rollers which is good for Hcl, they seem to keep it a secret, but this is Italy... Also a shout out for Stenner Tech Support, they jumped on my request...

    SWCG self install, acid injection question

    Many thanks for your replies. I think I'm guilty of using 'Stenner Pump' as a generic to describe the dosing pump I have purchased. I wish I had bought a genuine Stenner and will try and return the pump I have and get one. The pump I bought, model no. MP1S-PH 1.0, comes from a large and very...

    SWCG self install, acid injection question

    Hi everybody, my massive Autochlor SWCG has just arrived from Australia as has a Stenner pump for acid injection from a local, Italian supplier (Dosita). Taking the precaution to read the instructions first... but not before purchase,(Duh) I note that the acid pump is only suitable for Sulphuric...

    monster that eats chlorine in my pool

    Sorry about the delay in replying, been swimming in my crystal clear pool and clearing up after my daughter's pool party, she left behind a few cases of beer, so no hardship. So, twenty bowsers of clean clear spring water and careful dosing with bleach and a bit of dichlor to get some CYA and...

    monster that eats chlorine in my pool

    I think I have just found out what has been going on, I am trucking in water and chlorinating as I go, over enthusiastically as it turns out. I have superchlorinated and its bleaching out the DPD test. What threw me last time was the green/yellow cast to the water, which I now believe to be...

    monster that eats chlorine in my pool

    Thanks for joining in, Ski,mis, ammonia may well be an issue, my water supply is a creek in a farming area so ammonia based fertilisers may well be in the run-off. Don't yet know how to test for that but will find out. As for CYA, I have no reason to believe there was any in the fill water...

    monster that eats chlorine in my pool

    Thanks for your reply, and interest. It is exactly because the pool is not reacting in the expected way that I posted. During the whole process I monitored FC, TCL and CYA carefully for exactly the reasons you mentioned. I have used the FC/CYA chart for years and have SLAMed successfully in the...

    monster that eats chlorine in my pool

    In three days I have used 900 litres (237 gallons) 15-17% bleach, 60 kgs 132 lbs) Dichlor, and 60 liters (15 gallons) of muriatic acid! My pool is still green/yellow, bottom barely visible, a lot of sediment. Numbers this evening: FCL > 1, TCL 6, Ph 8.1, TA 9, CH 2 , CYA 28 . No, these are not...

    High TA, everything else O.K. do I need to do anything?

    thanks for the response, needsajet, just climbed out of the pool and got around to testing the fill water: FC 0.09 TC 0.10 Ph 7.9 TA 440 CH 89 So no real surprises there, I only tested for FCL/TCL in case something weird was going on upstream of the natural surface creek I take the water from...

    High TA, everything else O.K. do I need to do anything?

    Thanks for speedy reply, pooldv, Ph does slowly rise, about a point every two days which I moderate with muriatic acid. I'll throw a bit more in to get down to low sevens and see how that goes. I'm a bit unsure about the relationship between TA and Ph, I would have thought they would be 'lock...

    High TA, everything else O.K. do I need to do anything?

    I have persistently high TA readings, 300 to 400. Ph is stable, 7.3 to 7.7 as are FC (3-6) CH 130 and CYA at 40. Water is crystal clear and tastes and smells fine. My testing may be at fault, I use a Color Q 7 tablet version (I know, I know, but I can't get Taylor here in Italy and no one will...

    SWG Experiences and Recommendations?

    I have just realized that I asked much the same question exactly a year ago and got some good answers, duh! The beverages must be getting to me ... Anybody have any experience of Autochlor before I jump in with the big 92 unit?

    SWG Experiences and Recommendations?

    Thanks for your interest, it looks like the only fairly big swcg's available here are made by the Australian company Autochlor. They make a range that produce up to 92 g/hour, the RP 92. Plugging my numbers into their calculator their recommendation is from the 50g/hour running 12 hours a day to...

    SWG Experiences and Recommendations?

    I am just about to go the SWCG route here in Italy and would very much like to hear more 'real life' experiences of using the various brands. Hayward and Pentair are available at high prices, Zodiac is more commonly available. Any help would be much appreciated, Cheers Zed

    Olive Grove,thanks for replying,our Sabina is the one with the hills north of Rome, famous for over-exuberant entertainment of beautiful women in ancient times...

    Equipment not fastened to pad

    Just a quick note about the original question, it's generally a good idea to firmly fix pumps. They won't go anywhere (usually) but they will always twist a bit when switching on and off (torque reaction), which will eventually loosen or crack any rigid pipework attached to them, not that big a...

    Newbie, based in Italy, with green algae problem

    well done, similiar story here, I'm now besieged by friends and neighbours wanting to swim in our pool, all thanks to finding this forum. One question, I currently pay 40 euro here in Sabina for 25l drumsof 14/15% chlorine, much easier to handle than hundreds of ACE bottles, how much are you...

    Help! Dark Cloud from Return Jets at each Pump Restart

    I have exactly the same issue, my returns are all in the bottom of the pool and always give a rusty coloured plume every time the pump starts after being idle for a while. My pool is over 30years old with steel plumbing, so I assume it's just rust, it clears quickly and my guess that the only...

    specifying (sizing) an SWG for a big pool

    Hi Everybody, Just opened my pool here in central Italy, all good so far but I'm seriously thinking of going over to the 'salty side', not just because of the huge pile of empty bleach jugs but because the pool is at our holiday home and I'm not there the whole time. Our neighbour and local...

    Pool as Rainwater Storage Tank - Copper Sulfate

    I'd like to join in this conversation because I have both a pool and a large cistern and wonder about using them in conjunction with each other. My goals are not the noble ones of sustainability, just practicality and avoiding wasting water when I eventually drain my pool to do repairs and...

    new(ish) sand filter returning fine debris to pool

    quick progress report and dumb question, found some DE, my filter took 2.2lbs (1kilo) to increase filter pressure by 1 psi, from 18 to 19. Seems to be working really well, no visible plume of debris from the returns during vacuuming. Pool seems to be clearing but still a way to go. Dumb...

    new(ish) sand filter returning fine debris to pool

    Not sure if this is a pure filter issue or treating/balancing water, or both, but here goes; I have the usual 'greyish/milky water after shocking' issue. I know it can take time to clear but I've been at it for 12 days. I can see the bottom (8feet) just, but every morning there is a lot of fine...

    LaMotte Colorimeter - TesTabs vs Liquid Drops

    Just spotted this rather unnecessarily bad tempered thread... I've used a color Q 7 for the last year, can't get Taylor or TFT test kits here in Europe. Used it to get my filthy swamp under control and use it every day for routine testing. I can't comment on accuracy, I have nothing to compare...

    measuring up a freeform pool for a loop-loc cover

    Thanks for the heads up about registering the cover, beats the **** out of measuring up again in years (hopefully many) to come. For once things seem to be going my way with the pool, Loop Loc recommend 'simulating a rainstorm' with a hose to make sure the cover drains properly before it can be...
