  • wet/dry filter

    I think I killed half on my bacteria.... Here is what I did.. I put a new filter (lay over top of bio balls) in my wet dry tank.. Girl at the fish store said I would filter better than what I had..(a carbon mesh screen) so I put it in and thought great.. more filter.... NOT SO..... I checked my water today and all my levels were way up...... So I started checking... well come to find out, this new filter media does do good.. that half my bio balls were DRY..... seems as though the water flow thru it actually made like a funnel of sorts and directed the water to the middle and all the balls on the out lying areas had dried out...... On these wet dry system.. are the balls suppose to be submerged in water or just the water flowing over it.... because the way it is now, the balls are suspended above the sump area..... one thing I think added to my high levels... I took out all that coral and added new rock.... I am sure a lot of the bateria was growing on that rock...

    am I correct in thinking this is why my levels went up.... I have not added any fish... and everything was pretty much normal.... will that bateria that dried out re-start.... or are we a square one?
    Had about 900 gallons now I am tired and selling them off...

    Cope the area where the bio balls are at needs to be moist from the water at all times, mine do the same but because the area is closed off the area has a HIGH humidity and therefore never dries out.  Make sure that your drip tray (the part that should be below the exhaust of the incoming water line, but above the bioballs) have enough holes in it but not to many where the water will only flow through the middle only) On top of the drip tray is where you put your screening material to get all the large particles.

    The bio balls should for the most part be out of water but like on my wet dry its impossible for them all to be completely out of the water.. the bottom 2 lines of bio balls are submerged, but the remaining about 15 layers above is not.  

    Hope that helps.

      Thanks zulaab.... I was a little confudes... because I have a canister filter on one of my tanks and the bio material is submerged inside the canister.. (always wet) so I thought maybe these should be submerged as well..... thank you for your response...

        Cope -- this is what make a wet/dry so much more powerful than a canister.. because of the humidity effect on the bio balls the bacteria grows even quicker and a bigger colony than what you will get in submerged material.  (the bacteria as more oxygen to thrive with therefore they break down the materials faster etc...)  This is why your turn over rate is about twice as effective as compared to a canister in a wet/dry.
