Thanks Tim - that makes sense. The pump seems to handle it fine. It is a very small pool so even at a reduced flow rate there is plenty of water turnover in 8 hours. It certainly looks very clear. In the end, I decided to just run the cleaner at the normal setting as it was suggested to me...

Thanks Tim. I get your point about the walls not really needing it. I have such a small pool that the cleaner sucks up most of the debris very quickly at the normal suction setting - even an hour a day would be enough. I'm currently running the pump 8 hours a day and I figured it could spend...

I have a Pool Shark automatic cleaner which is fine and I have also borrowed a friend's Hayward Pool Vac Ultra. Both will climb the walls of my plunge pool all the way to the top but only if I increase the suction above the recommended maximum according to the Pool Shark's supplied flow gauge...

PPS I should point out the chlorine I sprayed is not the full liquid chlorine concentration - I mixed about a level teaspoon of granular chlorine to a pint of water and sprayed it right in there. It hasn't caused any noticeable bleaching as yet. I'm still a little tempted to raise the water...

PS I contacted a local pool maintenance guy who showed me the ropes when I was a newbie and seems to have a lot of practical experience. For that area above the water line, he suggested spraying some chlorine so that it gets right in (the trichlor tablet can only reach so far) and suggested if...

Thanks. I've discovered what might be the source of my black algae. At the very top of the pool there is a gap underneath a few of the horizontal terracotta tiles that border my pool. The tiles protrude further than the plaster so it is not obvious unless you run your fingers underneath...

I should point out that only about 10% of the pebbles are black - the other 90% are light coloured with the black ones creating a speckled look. The pebbles are no bigger than a match head so black algae bigger than a match head is more obvious. It's difficult though because two black pebbles...

I discovered about a dozen black dots/domes on the weekend around the quarter the size of a fingernail which were blending in very nicely with my black pebbles. About half were on my top step. Because I nearly always swim at night, I hadn't noticed them. I scrubbed all the ones I could find...
