I have had a successful 55 gallon planted for a while and I am now venturing into a bigger 180 gallon tank.
To increase biological filtration, as well as to hide all the equipment I have decided to build a sump. I've been reading a lot about planted tank sumps, and have looked at various designs. it seems that the main issues is the loss of co2.
In any case the tank I have to build my sump is 48x18x18 and I was wondering if anyone has a simple design for mechanical (perhaps a sock) and biological filtration chambers that is "Planted and CO2 friendly".
Thank you so much for the help.
