Beowolf Posted June 8, 2018 Share Posted June 8, 2018 Hi. I have a 8x4 JD pool 14.000 gallon. The pool has not been used for 8 years. It was a saltwater system, but the pump and other things where stolen, so I decided to switch to a cartridge filter. Now, after 2 weeks, the filter is clogged up by an unknown substance. (Se pic) I remove this amount every day from the filter, using a dull butter knife. I suspect the substance comes from the old pipes under the pool deck. My pool guy, TSP pools in Samui, say it is minerals in the water. But the water in the pool is clear. Any idea what it can be? Link to comment Share on other sites More sharing options...
Crossy Posted June 8, 2018 Share Posted June 8, 2018 My bet would be crud from the pipes too, just keep cleaning it out, it has to stop eventually. If it doesn't then there may be something living in the pipework and a super-shock of chlorine needed. Link to comment Share on other sites More sharing options...
Beowolf Posted June 8, 2018 Author Share Posted June 8, 2018 Thanks for the tip. I am thinking the same thing. But my filter is history, anyhow. Link to comment Share on other sites More sharing options...
kamalabob2 Posted June 25, 2018 Share Posted June 25, 2018 I've been to a pool pump room where stones and other items came into the pool pump filter. It was a broken water supply pipe. Crud in old pipes would not surprise me. Link to comment Share on other sites More sharing options...
Beowolf Posted July 1, 2018 Author Share Posted July 1, 2018 I have just changed the old, broken cartridge filter, and with the new one the PSI is down to less than 5. But the pressure and suction is excellent. I have seen that when the algea dries out, it dies and disappears. So next time my filter gets clogged with algea, I will simply use the old filter for a few days, and dry out the new one in the sun. And vise versa. You say super shock with chlorine. Is there any other chemical I could just put in my skimmer? Link to comment Share on other sites More sharing options...

Pooltrine is likely the most expensive, it is an algaecide & water clarifier. Link to comment Share on other sites More sharing options...
skills32 Posted October 2, 2018 Share Posted October 2, 2018 Oxygen kills algae. Hydrogen peroxide will oxidise your pool. Or just superchlorinate. Link to comment Share on other sites More sharing options...
