    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...
