Hi y'all,
The SWG (ChlorMaker IL) manual recommends CH of 300 - 400, so I've chosen 300 to be on the safer side.
It also recommends TA 80 - 120, so again I've chosen the figure that is closest to the recommendations on this forum (i.e. 80).
You can see that I'm trying to conform to what they recommend is best for the SWG hardware, and also what you guys recommend for spas / pools in general.
This is difficult, as they want the CH & TA much higher than what you guys want me to be operating at.
Having a SWG, and according to the Chlorine-CYA chart on this forum, my CYA levels need to be 60 - 80.
No figures are given below 60 for SWG systems, thus I conclude such levels are not recommended or simply don't work.
If such lower levels do in fact work, maybe they could be added / amended to this chart so I can use it.
Or at least, maybe you guys could tell me the missing Min FC / Max FC / Algae / Shock / Algae Shock figures for CYA levels 0 - 50 for SWG systems.
I finally got my water stabilised last night, after many long evenings with the test kit.
Now it looks like all my hard work may have to be thrown away, if I gotta drain and refill my hot tub to conform to these new revelations.
Bit of a shame, when I've tried to be as wise as possible, and tried to read & combine related threads of 'How do I use Chlorine in my Spa', borate use, CYA vs chlorine for SWG and the BBB system.
Yes, Chem Geek, I read and printed out the 'Chlorine use in Spas (Pools)' post, condensed and combined the relevant data into my current quick-reference sheet for my BBB / SWG / Borate hot-tub.
But, as mentioned, some data had to be altered to conform to Controlomatic's specifications for their SWG system.
Similarly, on posts here the salt levels should be 3000 - 3500, but the ChlorMaker operates at very different levels of 1500 - 2000, so again doesn't conform.
I hope I'm right in thinking that Controlomatic's specifications / requirements for the correct use of their SWG system takes priority over recommendations given here.
Or are they giving out figures that err massively on the side of caution, and can be overridden by your suggestions without any worries of wrecking my SWG's hardware..?
I'll fire them off another e-mail asking if I can conform to your much lower CH & TA levels (without mentioning you guys specifically).
Not easy to get all this right, I can tell you!
Regards,
D
