raise you ph to 7.4 - 7.6 and alkalinity to 120ppm then add some more algeacide. Sometimes with level of 7.0 and 40 the acid eats up the algeacide before it gets to do anything. Also sometimes algae pores are so small that it by passes the sand and sometimes even d.e. filters. Try backwashing to waste allowing the algae to go straight out of the pool. If you do have a sand filter try backwashing until clear, then rinsing for three minutes and then backwashing again for 30 seconds.. it really clears out the filter.
