Here goes my 100gl Sump. there is 40-50lbs of Ceramic Rings under the bioballs, its just hard to see. To lazy to add in the rest of my bioballs or scrape off the Silicone where the Drip Tray was. I have 2 small 100 Micron socks at the end of the Dual outlet
Other side of the tank is a FX5 with fish crap all over Lol.
Keep the Setups coming... there are some very nice and well thought out projects on this Thread
