Re: Undergravel filter
You should never mix up the gravel when vacuuming particularly over an undergravel filter....Skim the top of the gravel to get the debris sitting on top then only do small areas with a little deeper vacuuming at each water change.....You are only stirring up fine particles when you mix it up.....Make sure you are not over feeding.....If the gravel grains are too big or the gravel is too thin a layer, debris will be pulled quickly through the UGF and back into the water column......This is also stressful to the beneficial bacteria in the gravel.
I got off the porch and ran with the big dogs. Now I can't get back on the porch!
