I've been reading through all the Black Algae and Mustard Algae posts and was hoping for a little clarification.
I've been following the shock process and I'm currently going on day 3. The water is slowly turning from green to gray green to bluish gray, so I figure most of the floating algae is dead and the filter is working on clearing it up.
FC is still at shock level, though not at Mustard shock level.
I do still have some Black and Mustard Algae on the walls. The Black seems like it's been sloooooowly going away (starting near the waterline) and I've been scrubbing twice a day with a stainless brush. The Mustard hasn't gone away (haven't brought it up to Mustard shock level yet).
My question is how long do I need to wait to bring FC up to Mustard shock levels? Should I wait for the water to clear up completely? Should I wait until I completely get rid of the Black? If I go ahead and bring it up to Mustard shock levels will that speed up the Black removal process?
The water is improving pretty much on schedule as laid out in the How to Shock process, I just want to make sure I don't lose any progress I've made so far.
