    Lightbulb circulate vs filter?

    I thought of trying something different to the algae bloom with the pool opening this year. Has anyone tried circulating the water with chlorine until all the algae is dead and the water is cloudy? Then filtering the water thru a sand filter till it is clear? Does it seem to make a difference doing it this way or the traditional way of filtering while the algae is still "alive"/green? There are no leaves or crude in the pool. Just light green water.
    Thanks for your ideas. I learn so much from TFP.

    That's doable and a pretty good idea...especially with a cart or DE which tend to clog quickly. It is also a good idea if you really have a gunky pool.

    That's what I'm doing. I just got it rolling yesterday after some lightning induced downtime. Since it's cartridge filtered I'm watching the pressure and trading it out as indicated. 3 times yesterday! They sure clean up faster when it's just algae corpses. Still murky this morning but the filter pressure has quit rising very fast.

    I thought about cutting off the pump at night and in the morning gently hitting it with the vac/ brush.
    1) The size of your pool in gallons 4440.
    2) The type filter you have is an Intex 2500 gph and it has a re-useable fabric filter
    3) If your pool is an AG (above ground)
    4) Intex 15 by 48 metal frame.
    5) If you know, tell us the size pump 2500gph and the size (flow rate) of your filter.

    Thanks for your help and suggestions. These worked and the pool is crystal clear. Just need to vacuum and let the FC come back to swimming level just before the holiday party. ) Thanks TFP. Could not have done it without you. )
