Road construction causing pool problems?

I have had the worst last 2 years EVER dealing with my pool. I live right next to a freeway that has had construction going on the last couple years & last summer had a heck of a time keeping my pool clean & ungreen. I finally figured out a way to vacuum the sand off the bottom & right out of the pool & that helped. but this year is even worse.. my pool has been GREEN I mean really green all summer, I load it with chemicals & everything & it gets worse! I have been sucking this super fine almost sludge off the bottom several times & then it clears up for a cple days & it comes right back. I am assuming its because of them tearing up the road out here & repaving etc all summer & that crap is floating right into my pool. I am wondering if anyone else has had this problem & what they might have done? I am so upset I have spent over $500 on chemicals this summer & been able to swim like 10 days total. All my chemical numbers have been correct, same as every other year. I am ready to empty every last srop out & just power wash the whole thing out & refill it, but thats alot of work & they are still working on the road for a cple more years out here. Wondering if I should contact the road Dept & discuss this..
I have a 24' above ground, i do not have sand pump, its a tall filter hayward. my biggest issue is I have one with a fence built into the top of the pool walls so not easy to access around the entire pool from outside.

We aren't really going to be able to help without a set of current water testing numbers taken with a drops-based kit -- no test strips. You say that your chemical numbers have been correct but that obviously can't be right or the pool wouldn't turn green. (Dirt won't turn a pool green.) The kit we recommend is the Taylor K2006 or 2006C which you can get through the test kit link in my signature below. it is only available online so you need to get something to use in the meantime. Go to Walmart and see if they have the HTH 6-Way kit (not strips). If not, at the very least, get a cheap OTO/Phenol Red (yellow and red drops) kit. Also, get several jugs of plain, unscented 6% bleach (generic is fine), a couple boxes of 20 Mule Team Borax (laundry aisle) and a jug of distilled water.

Post back with numbers. Also, please put your pool's information into our pool chart as it makes it easier for people here to help you.

What kind of filter is it? DE? Cartridge?

Just to echo what Watermom said; construction doesn't cause algae. It might make your pool more prone to get algae, but if you have your chemistry right, you won't get algae.

The problem is, pool stores and especially pool chemical companies make FAR more money if your pool is messed up, then if it's running smoothly!

Give us the info, and we'll help you fix the problem.
