I'm just about to start with a small Spa, and will probably use a combination of dichlor and calcium hypo.
Can't use natrium hypo cause it's not economically available in Sweden except in too large quantities for a spa.
With a spa I understand I need to add chlorine pretty much daily, or at least everytime we use it. That's easy enough with quickly dissolving dichlor, but that alone will build-up cya too quickly. I have very soft water, so calcium hypo will work well, but the procedure of dissolving it in a bucket every day isn't tempting.
Thinking about pre-dissolving some calc hypo in a 2 liter bottle, maybe to a chlorine concentration similar to 5% bleach. I could then easily use a small amount of this liquid daily, having enough in the bottle for 2-4 weeks usage maybe.
Any dangers with this idea, e.g. is dissolved calc hypo stable in such concentration, or other drawbacks?
