My Battle with the Green Abyss
Hello all. I've been using this site the past couple of weeks as I'm attempting to clear up my
pool. I decided I would registered and get in on the action here. I'm working with a 30k gallon
above-ground with a vinyl linyl and sand filter. The pump has been out the past couple of years
and the pool has been uncovered. Needless to say, I am trying to clear a major green algae
Here's what I'm working with on day 4 after my thorough cleanout and brushing:
It's still pretty bad.... there are three steps there and the 2nd one is just barely visible.
I started by testing the TA and ph. Adjusted TA ~90 PPM to using baking soda . Adjusted pH to 7.4 using dry
acid. Added 3 lbs granular shock and 3 stabilized chlorine tabs. I ended breaking up the tabs for
Found pool school and pool calc. Wonderful, gotta love the internet. CYA was measured at 15-20 PPM. Added enough liquid bleach to get up to 12 PPM. Measured FC again after 30 mins and it had dropped to around 9, so I
brought it back up again. This cycle continued. I also brushed as well as I could, but my deck doesn't give me much access to half the pool. My pole being messed up doesn't help much eiither. The water has turned more of a blue color, but is still very cloudy/murky.
I continued monitoring FC as much as I could and kept the pool at shock level. While brushing, I
lose my brush and half my pole...... great. Water still looks terrible.
I let the FC drop today while at work. I came home and tested the FC and it was at 2. The water
still looks horrible and my brush was in the middle of the pool, so into the abyss I went. I
retrieved my brush and noticed the middle of the pool was loaded with leaves. I got my net and
pulled net full after net full of leaves coated with green algae off the bottom. I spent an hour or
so doing this, then brushed the whole thing thoroughly from in the pool. I proceed to
thoroughly clean myself with antibacterial soap and went back out. I backflushed my pump,
cleaned my strainer, and brought the FC back up to 10+........ and the cycle begings again.
Hopefully removing the solids and getting the good bushing in will help.
Any suggestions are greatly appreciated. I'm going to try and keep this updated.
