Thanks bud.Stunning bass Koji!
They look to be in great care.
Keep the updates coming.
And how about a k1 filter tutorial...? Like how its made and how it works.

what kind of gravel are u using???
You need time for the bacteria to start growing on them. My suggestion is start with slower flow rate before going for heavier flow rate. The reason is to give the bacteria chance to grow on them.^^Ahh yes. Awesome link.
I need to order some k1 for my growout tank.
