Found 2 bags of old castle sand last week, and could not pass it up. (Locally here in Oregon it hasn't been readily available).
I added it Friday to my 90 gal
tank without rinsing because I wanted all the big and small grain sizes that were in there. I know the storm will last awhile.
My question is - I need O2
(via water circulation) to keep my bacteria healthy and to continue my cycle (nh3
just dropped last week - n02 is still quite high). But if I keep running my pumps isnt' this gonna take forever to settle down?
