What kind of fish?ccdoido38;1397812; said:40ppm isn't too high even thought it says danger on that test kit of yours.
scientific research has shown that nitrate is relatively harmless to freshwater fish. however many people believe low nitrate levels are more natural and therefore better for tropical fish.
my neighbor had his tropical pond at 300ppm for 2years and all of the fish were healthy, active, and growing.

sounds more mechanical than biological.West1;1397968; said:I have a bio filter (2 of them) on my over flow.
One is a white net from pet-co (used for stuffing media) that I placed around the cylinder of the overflow (used like a sock), and the other is a pad before the water goes down to the Sump. What ever makes it down to the sump I just hope it goes back to the tank (so the Rena can pick it up) from the free cycling powerhead that I have on one side of the tank (so the water cycles in a circular motion).
What do you think???? I've been trying a few diff things and this seems the most effective
there's no link. it's comes in the box when you buy rena filstar media.rallysman;1397818; said:What kind of fish?
And can you link to that research? I've never heard of that. Interesting stuff though
