| 1219911 | 2011-07-30 05:01:00 | Chlorination: I assume you will use HTH (high test hypochlorite), which is Calcium Hypo Chlorite. When added to water it dissociates and leaves a residue of Calcium Hydroxide which will add a load to your filter, indeed if it the filter is not backwashed often enough the Calcium Hydroxide turns to Calcium Carbonate (limestone) and can permanently clog the filter. I once saw a school pool with a layer of cemented sand about 100 mm thick, that had to be broken up. It is far better to add the HTH to a bucket of water, let it settle, and then decant the liquid into the pool. Discard the residue. I agree entirely about Chloramines. | Brucem (8688) | ||

| 1219914 | 2011-08-22 08:09:00 | Ok so we have actually moved into the property now, went out and had a look at the pump / filter today, It has 6 settings: Filter (I'm assuming this is 'normal' mode?), Closed, Backwash, Recirculate, Waste and Rinse. Also I believe it is a sand type filter (big round black drum). The pressure gauge is showing 170 Kpa, which is 1/8th of the way on the 'clean' side (one side of the gauge is blue and marked 'normal', the other is red and marked 'clean'. Now I assume that means that the filter is clogged up and needs back-washing. So do I just set it to backwash and leave it for a few hours? Complete pool novice here as you might have guessed. One more question. The previous owners left all the accessories including a vacuum and hose. Where does said hose connect? |
