How long does it take?
I just finished setting up a 40 gallon breeder tank with 2.5 inch of Miracle Gro Organic Potting Mix, capped with an inch of Diamond Black sand.
After putting down the plants, setting up filter (Rena XP3), turning on a low light fixture on 8 hours/day for the last 3 days. The first day, the water was kinda murky, then 2 days later, it was very dark, brownish color, and it's getting darker every day.
I'll do 60% WC today.
My question is: how long does it take for the water to get clearer. I know the soil is tanning the water but I didn't know it can become this dark color!
Or am I doing something wrong here?
I didn't wash the soil, only picked out large objects in there.
Thanks for any advice you can give.
