I finally filled my 4x2x2 monster sump after realising 240 scubbies and 500 bio balls wasn't going to fill this bad boy.
The sump swallowed 660+ scubbies and 950 bio balls.
As you can see the 500g tank has turned a dark cola colour from the two extra large logs the have been soaking in it for 3 weeks.
They have finally sunk and I'll do a water change, vac up some of the dead bugs and bits that have fallen off and start the canister stocked with carbon to keep the tannins in check hopefully.
Should I add some shell grit (Calcium carbonate) to keep the acidic tannins in check (neutral) or will the carbon be enough to remove them?
I am waiting for my 25w laguna UVC to arrive and then I'll plumb the sump to the tank ready for water.
I posted a few pics of the fish waiting for their new home to be ready.
