Ok. Got it all put together this weekend. Went through a lot of silicone and gave myself a couple of good cuts. But here it is, not pretty but it works.
There are 3-4 small leaks in a few of the baffles but I don't see why it would be a problem as the majority (I'd say 99.99%) of the water still runs through all the stages over and under the baffles.
Also, I'm having a problem with small bubbles being created by the initial water overflow splashing in the first stage of the overflow box. They go through ok but I'm worried a few might clump up at the top of the u tube and create a large bubble restricting the overflow rate... Anything I can do about that?
Another problem that arose when I was tinkering with my return line was a siphon back to the sump when I turned the pump off. This really worried me cause I'd hate to have my power shut off and then have my room submerged in an inch of water.
After my next paycheck I'm going out and buying some media. Thinking of using bioballs and either crushed ceramic or lava rocks.
How do you guys have your return line connected to your sump? In the picture it's just resting in it but that is temporary.
Sorry trying not to overload but I am excited to get it all finished so I can start my cycle.
