Opening Algae Problem

[skinney1086]

Currently I'm just using the HTH 5-way test kit from walmart.

Pump: I'm not 100% on the pump. I believe it's a 1 or 1.5 HP Pentair Challenger.
Filter: Hayward Sand Filter

I actually haven't taken the cover off yet. I'm am tonight when I get off work. So I don't have any readings.
I didn't know how long it would take to get a reply, which is why I posted already. :-)

The past 2 years when I opened it was a full algae outbreak. It usually took about 8-12 (maybe more) gallons of "pool" liquid chlorine.

So I was just looking around to see if there was anything different I could do. Any advice is greatly appreciated.

Thanks
