Has anyone tried the regeneration process for Seachem Purigen? I have tried bleaching it base on instructions by Seachem. But dun seem to be able to get 100% or anywhere close to it kind of regeneration. More than 70% of the beads are still dark brown. Have soaked for 48 Hrs without success and now doing so with new bleach for another 24Hrs.

Should be... bought from C328.. btw, what's Ivan's number?

I just experience electric current leakage from the tubby float switch. Small amount only as I felt it only when I touch the water in the sump tank but no feeling in the main tank water. Tested all submerged equipment and confirm the leak comes from the tubby float switch. Anyone ever experience this? Does this mean I have to change the float switch? Only using it for a few months leh.

Nitrate levels in FW setups can also get very high due to reasons of high bioload and also keeping of large predatory fishes. My DSB thickness is about 8 to 9 inches deep. My thinking is that the due to the depth and compactness of the sand, extremely slow water flow through due to resistance of the sand media. If only water flow over the top, hydrogen sulphates may form at the bottom of the DSB which would be harmful to fishes. Also, the compartnemt prior to the DSB is full of Biohome, CC and CR where aerobic Bac will use up most of the oxygen in the water. So water reaching the DSB would be quite oxygen starved the anaerobic Bac denitrification process.

Hi all.. a new member here. Although I'm not into marine setup but am very interested in the filtration technology for both marine and freshwater setups. I currently have a 6x2.5x2.5 feet freshwater setup with a 4 feet sump. My query is, I setup a compartment in my sump for DSB. I'm using grade 0 sand also and have both under & overflow for both inflow and outflow of water. I'm quite sure that DSB works in freshwater setup but I do here of people saying it doesn't. Can anyone clarify on this and the reason if its true? Also, how long does it usually take for a DSB to mature?
