Trailor trash, can you explain the water flow for me step by step(sorry if I'm being a pain)?
Here is mine: Water flow from the prefilter of the display tank down to the wet/dry, over a cotton filter pad. Once the water seeps through the filter pad I have carbon in a filter bag over top of my bio balls. So the water is hitting the carbon first then the bio balls. Then on to my tiny sump(same wet/dry). Where I squeezed two pumps in there one for the skimmer (Berlin Turbo Classic)and the other is a Rio 3200 for the return water being pumped back to the display tank.
I had to make due what what I had. My friend gave me the wet/dry and it was only rated for a 100 gallon set-up (I was clueless when I first set my tank up).
I'm thinking of building a system under my tank to supply my mechanical and biological needs all in one.
