Ok, a few unrelated questions, but all are needing to be answered.
1. I have two AquaClear 20 HOBs on my 20l. On full power the flow is really strong. Thing is, if I lowered the flow, wouldn't that reduce the GPH and defeat the purpose of having two filters?
2. Also regarding the above-mentioned filters: They are both right next to each other. Is this the best way to position them? Should I move one to the other end with the heater? Move one onto the side of the tank?
3. I'm getting a pretty long piece of Manzanita on Monday. It's from ManzanitaBulworks.com, so it probably has all its tannins. I know tannins are good for shrimp and all, but since this is a display tank, should I soak it? Soak it in warm water? Boil it somehow?
No matter how hard you try, you cannot escape this hobby. You have been warned.
