Can I Make My Own Chemical Treatments?
Posted 20 July 2008 - 07:10 PM
Of the different things in the kit, what can I use as a homemade substitute for each of the chemicals to perform the same task (e.g., baking soda works for raising pH)?
Are there some that I won't even need?
Do I really need to use as much as they say I do?
The following are the chemicals that came in the kit:
Water clarifier (emulsifier)
scale and stain preventer (for use during fill-up)
Mineral purifier (which came in the form on a narrow cylinder that's supposed to go inside the filter)
Thanks for the help!

pH Up -- Sodium Carbonate; same as Arm & Hammer Super Washing Soda (careful: NOT the laundry detergent); note that if you want to raise the pH without raising the TA as much, you can use 20 Mule Team Borax; if you want to raise the pH with no change in TA, just aerate the water.
Alkalinity Up -- Sodium Bicarbonate (synonym: Sodium Hydrogen Carbonate); same as Arm & Hammer Baking Soda
pH Down -- Sodium Bisulfate aka dry acid; no direct substitute; Muriatic Acid is generally too hard to handle for the spa (though it does work)
Calcium Hardness Increaser -- Calcium Chloride; same as Peladow melting salt (or DowFlake though that is less concentrated)
Water Clarifier -- don't know of substitute
Non-Chlorine Shock -- Potassium Monopersulfate (MPS) -- don't know of substitute other than chlorine (unscented bleach)
De-Foamer -- don't know of substitute, but if you keep your Calcium Hardness (CH) at 120 ppm, it should help to prevent foaming
Scale and Stain Preventer -- don't know of substitute
Cartridge Cleaner -- use Trisodium Phosphate (TSP), but the real stuff such as found in Red Devil TSP; automatic dishwashing detergent is OK as well.
Granular Chlorine -- use Dichlor initially cumulatively for [EDIT] 33 ppm FC (which is 30 ppm CYA) [END-EDIT], then switch to unscented bleach, BUT may have pH rise more than you'd want (especially with ozonator or aerating jets) [EDIT] so need to keep the TA low and can use 50 ppm Borates [END-EDIT].
Mineral Purifier -- don't know substitute but you don't need copper/silver if you maintain chlorine or bromine levels properly.

Yes it would work, assuming there aren't some sorts of impurities or additives (I doubt there are).

So, starting this over to get clear, what makes for a simple chemical regime, assuming balance? I have the Floating Frog but it gets in the way and caught in the skimmer. It has bromine and minerals. Do i need both or can i merely toss in some bromine or chlorine manually say weekly? And is that necessary as I have an ozonator?

I have just bought both from Tesco Extra. The Sodium Bicarbonate cost about 8 times less than my local spa shop! Both are new products in their 'naturally' range of cleaners.
I have also read that large Boots stock Borax.

I am looking to source a shop to buy 'Sodium Bisulfate aka dry acid' (to reduce PH) in the UK. Anyone got any suggestions, or UK equivalents to achieve pH down?

Or if you really want to avoid your spa shop, you could also use Muratic acid (which is available at hardware stores). However, that is strong nasty stuff. If you do go that route, I'd dillute it with water (pouring the acid carefully into water, so that it is one part acid, three parts water).

I like the idea of Muratic acid. Do you know any brand names/suppliers under which it is available in the UK?
