Thanks! I've made a lot of mistakes but doing everything slowly gives me a chance to really think things through. I haven't done the sump yet but I've planned it. I'll have a glass baffle 8" high on the left for the overflow/skimmer department. The middle compartment will have an algae scrubber and a gfo reactor. I'll have a second 7" glass baffle next to that to make the compartment for the return pump. I'm planning to use all pvc with multiple unions so I can take it apart to clean it. The pvc for the overflow is 1" and the return is 3/4". That's with the glass-holes overflow and return kits. I might paint some of the pvc with Krylon Fusion just so it looks cool. There will be an acrylic "wall" to the left of the sump that will protect my electrical stuff. I'm going to use industrial-strength Velcro so I can take it off when I need to. I'll probably frame it with wood to make it a little more sturdy. I'll show pics as soon as I get it done.Nice work on your setup so far. Read through your whole thread. Did you finish your sump? If so, care to share the plans? Mine are still fluid and could always use some ideas.
