Our pool is 1/2 filled with water. We stored the DE filter and the pump over the winter. But due to some bad storms over the winter...I guess it cause algae to start. My question is this. Should we go ahead and fill the pool the rest of the way up with water, connect the pump and filter and treat the algae...OR...should we just pump out the algae water, scrub down the pool, and refill and treat the algae that way?? This way the water isn't so green and maybe won't be so much work in treating the algae??
