I have a new, larger above ground pool this year and it is always being overrun with algae… i use 2-3 bags of shock ever 3 or 4 days, but it doesn’t seem to help much. Any ideas?

Answer:

The key to understanding why this is happening is to understand what is causing the algae. Are you running out of chlorine so that the algae can grow (chlorine tests 0 or very low)? Is there something being introduced to the water regularly that is helping algae to form (leaves, animals, fertilizer overspray, etc.)? Once you understand this, you can treat accordingly. Using a regular algaecide treatment in addition to the chlorine can be very helpful as well.
