starting up after winter

Online only -- I've got links for a large bottle on the test kit info page link in my signature.

I need to post pictures but you can refill your CYA bottles by flipping the dropper tip off, filling the bottle, and then popping it back in.

Ok.....one more question!!! Will the tsp/90 phosphate free, substitute work?

[PoolDoc]

It might; I don't know.

In general, the TSP / STPP substitutes are FAR less effective than the phosphate products. If you concerned about phosphates in the wastewater . . . fertilize your garden with it, when you're done. But if you get a good garbage can, and spray off your cartridge before soaking, and add 1/8 cup of bleach with each cartridge . . . I don't know a reason why you couldn't use the same solution all summer. You'll probably need to add another cup of TSP mid-season, though.

Should I be adding Stabilizer to keep chlorine in?

[BigDave]

We don't know if you have any CYA, you probably don't but until you get the refill...
Do test and add chlorine as often as possible so it doesn't go low.

Ok so the water is now milky blue before brushing, but after brushing turns greenish/brownsih until everything settles. Is the algae dead?? I still have the oto kit. Will it actually turn orange if my chlorine is high enough?
