A3M0N Posted December 19, 2022 Share Posted December 19, 2022 I am a tinkerer. I like to make simple things if I can, I don't mind reinventing the wheel, it's fun sometimes. This filter, for example, is made of 1/2in PVC and is air powered. The inlet is on the left side, it goes down under the substrate and across to the uplift tube. The blue line may look a little wonky, but it's just to show the outlet is aimed at the front left corner of the tank, it's not actually aimed at the bottom corner. Most outlets and inlets are close to each other on the same side of the tank, does that result in better circulation that what I have made? I'm looking to possibly remake this filter, one for better flow, two because I made an oopsie when building it and it ended up too short. The pipe across the substrate is too close to the surface, rather than at the bottom of the tank, so it gets in the way of planting and hardscape. Would it flow/circulate better to have the inlet/outlet at the back right corner, aimed to the left corner? And the CO2 diffuser should be at the opposite end as the filter? Would 3/4in PVC be a better size? How about a spray bar outlet, what do you gain with a spray bar? This is only a 10-gallon tank with small fish, I don't think I need a lot of power, but do want it to a good job circulating. I'd like to keep it air powered for simplicity, and I don't like the idea of filtration that could not restart or overflow in case of a power outage.
