There are several things you can do to reduce NO3
in your system, even while using a wet/dry. Proper stocking levels, appropriate feedings and regular PWC
will help you reduce your NO3
. I have a wet/dry that I have sort of converted. It is a Pro Clear 150 sump. I removed the Bioballs from the middle chamber as well as the tray they sat on. I filled with middle chamber with about 30# of LR
rubble and I keep it fully submerged. My NO3
is steady at about 2ppm. Another good trick is to turn off the wet/dry while you are feeding so the food does ot get sucked into the filter, this is your biggest source of NO3
. Bottom line is that you should be able to manage your NO3
even with a wet/dry.
