Timmie,

I'm still learning (every day!) but I'd keep the filter running and not worry too much about vacuuming until the filter clears the water up somewhat. If you're able to find manufacturer and model information on your equipment, please include it because someone here is probably familiar with how it operates and can suggest how to get the vacuum working right. In answer to your question about volume, yes, 70K litres sounds about right for a 17x33 ft pool.

You mentioned Javex - I believe it is bleach (chlorine), rather than borax. It sounds like you have plenty of chlorine already. :-)
