Sorry, i posted in haste last night to the one i had going about algae. I meant to post here about DO. I took some depths and moved the Diff 1 deeper. I'm going away later this week, off to Baja for a week chasing tuna so i'll test DO and clarity when i get back. Hopefully i can test some change in DO beyond 8ft deep by then.
