Rhysmachine101 Posted September 8, 2011 Report Share Posted September 8, 2011 Ok so my barrack is ready to be cycled and I was wanting to get some suggestions on the best filter mediums for the job. Here is a side on pic of the filter medium compartment: water comes down the tubes into the far right compartment and comes up from the gap at the bottom into the left compartment. Volume is 5.4L to fill with filter media... What do you recommend? Link to comment Share on other sites More sharing options...
shadoh Posted September 8, 2011 Report Share Posted September 8, 2011 My barracks sump has 2 sections for filter material. I have charcoal topped off with filter wool in one (50/50) and ceramic noodles in the other. It seems to do a good job. Sponge would also be a good thing to use :) Link to comment Share on other sites More sharing options...
Rhysmachine101 Posted September 8, 2011 Author Report Share Posted September 8, 2011 (edited) Charcoal, hey? Thanks shadoh! Any other schools of thought? Any material I put in here is going to be submerged mostly. Edited September 8, 2011 by Rhys Link to comment Share on other sites More sharing options...
Bettarazzi Posted September 8, 2011 Report Share Posted September 8, 2011 In the talk that Scott Haymes gave at EDAS he suggested that filter material should go something like this: 1. Pre-filter media designed to trap solid waste. Some ceramic noodles are designed specifically for this. Fairly open sponges are also good. You should rinse out the pre-filter media regularly. 2. Biological filter media like Seachem Matrix, sintered glass or ceramic noodles (make sure you get the biological filter kind not the pre-filter kind). Make sure you have enough volume of biological media so that the water will take about 4 seconds to pass through. You might have to slow down your pump or use more media than what's recommended on the box to meet that 4 second requirement. 3. Chemical filtration media like carbon or Seachem Purigen. Carbon needs to be replaced monthly while Purigen can be recharged in bleach. Get Purigen that already comes in bags. The loose stuff is a pain. 4. Lastly a fine sponge to remove any fine particles. I'm planning on re-doing the sump in my barracks along these lines. Link to comment Share on other sites More sharing options...
