How should I modify the marina slI'm 20 filter? It already has an intake sponge.
Yes that will work just fine also. De-nitrate is just a smaller version of Matrix. Actually it probably will grow some anaerobic bacteria.abarb said:Thanks for the video. I have some seachem denitrate. Can I use it instead? I know it won’t grow anaerobic bacteria though since it’s over 50 gph..
Yes but you could follow the video and put all that in the first cartridge space and use the last 3 for mesh bags of Matrix.abarb said:Does this look ok for mechanical filtration?
OK, but you said it yourself, you cut the flow in half and now you have less than 50 gph for your anaerobic bacteria. That flow is plenty in a 10 gallon.abarb said:
I think you have enough info to make your decision now. Good luck.abarb said:I think the sponge can also biologically filter. I can use one space for matrix and one for biomax or ceramic rings. I'll put some lava rock in the tank. Is that enough?
Just to let you know, this is what I did with my Marina S20. I traced out the cartridges onto 3 mesh filter zipper bags and sewed them to make a perfect fit into the area in the S20. After doing this I never really used the S20 in my 10 gallon. I looked at my 75 gallon and one of the filters on it was a new Tidal 55. I said, 'what the heck'.abarb said:Thanks for the help.
