No need to PM, someone else might know of a better way and tell us.
1) any reason you use lava rocks instead of bioballs, or pot scrubbies which are popular among DYI projects
Probably not, I just always have crushed lava rocks lying around from making potting soil for my cacti and aquarium soil. It is possible that the minerals in the lava rocks might promote better bacterial growth but I don't have any proof of that other than the excellent way it works for me.
2) would a rubbermade tub or a stock tank work for a sump instead of another tank?
Oh yes any non toxic container will work as long as it fits in the space available.
3) does it matter where the overflow is placed? i assume you still have to vac the bottom of your tank to remove the crap on the bottom (literally)?
I like to place it in the corner of the tank so I can use a bubble wand to help direct detritus into the over flow but other than that it can be placed where ever is most convenient. No I do not vac the bottom of my tank, I use sand with my special potting soil under the sand. (Yes I use fine sand) Detritus is a natural part of the freshwater environment. I do use MTS to help keep the bottom free of left over food and fish poop but other than using a bubble wand to direct water flow toward the over flow I do not attempt to remove detritus.
4) does it matter where the return is placed?
Maybe, I put the return near the end of the tank with the over flow and direct the return away from the over flow to help water circulate around the tank. Just make sure the return helps circulate the water in the way you need it to.
5) what is the difference between putting the rocks above the sump? some people put their media inside (submerged in) the sump i think? i assume thats where "trickle filter" comes in, but what are the advantages to doing it your way?
When the rocks are above the water they are exposed to much more air and the extra oxygen results in a higher rate of bacterial action. The faster the bacteria can convert ammonia to nitrite and then to nitrate the better it is for the fish.
6) how do you know how full to fill the sump when setting it up?
You fill up the tank until it begins to pour into the sump, then you fill up the sump to the level you want. When you start the pump the level in the sump will drop as the pump transfers water to the tank. When the level stabilizes mark it with in an easy to see way and never fill the sump up beyond this while the pump is running. That way you can judge how much evaporation has taken place with out shutting down the pump and allowing the filter to drain.
7) as for the holes in the buckets (both bottoms) how many holes, and what diameter?
The distribution plate is about 11" in diameter and has around 80 to 100 6mm holes in it. Your pump flow will determine how many holes you need. Make sure you test everything before installing it it's final place.
8) how loud is this setup?
Not loud to me but I like the sound of trickling water.
** to clarify, i am just wondering and curious why things are done a certain way, i am not questioning the "correctness" of your setup at all
Always question dude, never accept anything at face value, you might misunderstand me and want clarification or sometimes you might see a better way. I've been keeping fish for 45 years but the best part is learning something new. Once you know everything it becomes boring to me!
