Green won't go away!

[bryansanders]

All my readings are:

FC 16.5
CC .5
CYA 40
pH 7.5

FC before bed time was 16.5 and this morning same number. The only thing that changed was the pH from 7.2 to 7.5 from adding baking soda.

I am on day 2 of slamming...any suggestions? Add some DE?

Day two is just getting started. If you are following the SLAM procedure, you shouldn't be adjusting pH or TA. Adding DE is for later in the process when you are trying to clear dead Algae, and dead Algae is greyish/whiteish, not Green. If its Green, its still alive.

Too soon to panic.

If there's any organic debris lurking in the depths, that will slow things down. Vacuum blind if you have to. And brush brush brush to scrape off the slimy biofilm that protects the algae core from the bleach so it can be killed.

There's also a slim possibility that some of the coloration is due to Iron in the water since you fill from a well. That, too, may filter out if it's precipitating due to the high FC levels.

Ok thanks for the encouragement, I am running an Aquabot 24/7 along with the SLAM. Hopefully that'll kick it some.

*Update-Day 3* FC was 15.5 this morning so I got it back up to 16. The Aquabot is only picking up a leaf or two and some white grimy stuff. Should I keep running it? The color is about the same as yesterday, can't see the bottom just yet...

If that bot keeps things stirred up, I'd leave it run. You need that floating debris to find its way to the skimmer so it can get sucked away and filtered out.
