Intex Ultra Frame 16' x 48" build

I hope I'm doing things right. I've been able to skip dosing a couple of times now but it doesn't seem right. Yesterday's levels were pH=7.4 and fc=7.5.
Did a quick check today with the HTH kit and fc is still above 3.5 and pH still looks OK. We did get a good amount of rain today so if levels look ok later I may add a half dose anyways since i skipped dosing yesterday. A week in and I've skipped twice already. Does this seem right to you guys?

Your pH is fine, so no Borax needed tonight. As long as your pH is 7.3 or higher, I would skip the Borax.

Since you lost 4ppm of chlorine in the past 24 hours (since your CYA is still pretty low), you'll probably want to go ahead and add some Dichlor this evening. Don't want the chlorine level to drop to 0 tomorrow and risk algae in a new pool!

(As you use Dichlor and your CYA level builds up, you'll find that your chlorine won't disappear as fast.)

I actually only lost 1.5 ppm for FC. When I tested this morning with the HTH kit all it could tell me was that FC was over 3.5 (since that's the highest it goes). When I tested this evening with the Taylor kit, it showed I was at 6 ppm and pH dropped to 7.0.
I added a half dose of Dichlor and a full dose of Borax. I find it a little strange that I'm not losing a lot of FC with little CYA built up since the pool's only been filled for a week.

Has it been cloudy in Manitoba? That would do it.

(Also, cooler water temps slow chlorine use . . . and I'm guessing your pool's water is not at 30 deg C!)

It's been alternating between sunny days and cloudy\rainy days. Pool is definitely not at 30 deg C. More like in the low 20's.... we haven't had a good stretch yet where the water can warm up. They say starting tomorrow we may get it though, about 5 days straight of sun and hot temps. Hopefully it happens but they said the same thing last week too.

[PoolDoc]

Cold water + lots of clouds will definitely reduce chlorine consumption.

thanks Pooldoc, that makes a lot of sense
