Winterising Our Pool ?

Hello from a new 'recruit' to this forum.

May I ask a simple question please ?

I am about to put Winter Chemicals into our pool.The PH and Chlorine levels are as required.
I want to retain the pool level and not reduce it below the skimmers .
I intend to run the pump over winter , a couple of hours a day and the same at night.

Is it OK to run the pump with the winter chemicals in the water ?
Is there anything 'corrosive' in the winter chemicals that may damage the system ?

Sorry to ask a question which is probably common sense to you all !
I don't want to make a mistake.

We live in S.W.France where the winters are usually 'moderate'. If it gets very cold and possibly freezing I shall run the pump more frequently.

Robin, welcome to TFP!
What do you mean by "winter chemicals"? Are you planning on covering the pool? If you're not planning on doing a full closing, then I don't think you need to add any special chemicals. My pool stays open all year, and I don't do anything different in the winter.

What winter chemicals are you adding?

If your running the pump during the winter, then I would assume your maintaining your water balance for chlorine, PH, Alk, etc. If so, then you don't need any special water chemicals.

Welcome to TFP.

If you're going to run the pump anyway you don't need to add anything except your normal method of chlorination unless it's a SWCG. Below about 10ºC it won't work and you'll have to manually add chlorine to maintain the FC.

ETA: Typing at the same time as the others.
