Now for fun take those pictures to the poolstore and show them the before and ask what to buy. Then show the after and tell them how you cleared it up.

There are byproducts and fillers in bleach that really shouldn't be in pool water and can wreak havoc on pH & alkalinity. Regardless, when attempting to clear a mesh covered pool in the spring, the MOST important thing is filtration. Without adequate filtration, you can dump all the bleach (or other sanitizer) you want in the pool and it's not going to make a big difference. One way to keep the pool from getting to such a nasty state, is to put a floating chlorinator in it when the pool is winterized. Periodically check & refill throughout the winter and even add additional algaecide if needed. If you religiously do this, without procrastination, then chances are your water will be clear when you remove the cover and save you days or weeks of clean-up time. The other option is to buy a SOLID VINYL COVER! Your water will look the same in the spring as it did when you winterized it.
