I only speak from experience. If you are set on having it be on a central system, you really should look at some of the examples out there. The easiest to maintain and the most efficient to use are the simplest ones, usually.
IN the end, you will spend more time looking at your tank instead of what is under and behind.
With a planted tank, efficient mechanical filtration is essential. I recommend using filter socks on the input into the sump for quick, easy change out.
Allows you to switch out prefilters without even stopping flow. Plus it will make maintaining the rest even easier.
In the end you will find what is best, but you might be like some of us and end up doing it 3 or 4 times and spending wayyy too much before you get it just right. Thats what most of us do in most of this hobby.
I will order some of those socks when I start building the sump. Those are cool.
Don't worry about it. It's hard to interpret people's emotions on these forums anyways. I really do value your opinions though. I have revised the drawing to a much simpler form, fell free to bash this new one.
I will probably make the sump a 55 gal instead of a 20 gal now since I have extra space without all of that stuff in the mix.
The new design looks alot better. The only thing I would question is the heater/chiller on the 55 gal output line. I don't know how efficient it will be in chilling the other tank. How about having the chiller/heater on it's own loop in the sump? I'm not sure if that will work better. The heating and chilling is going to be the hard part since the smaller tank will raise/lower temp a lot faster than the bigger tank.
Thanks! Thanks to water's ability to absorb and release heat, even chilling or heating the 55 gal will keep the 20 at the same temp. Even though you are right, the 20 could potentially waiver faster than the 55, the water would not have a long enough time inside of the 20 gal to raise or lower the temp enough. The equilibrium in water is faster than that tank can fluctuate. Water is awesome! The reason for not having the chiller/heater on it's own loop is to limit the number of connections and pumps. I like this design a lot now. I think there is definite potential for improvement, but this is significantly better than version 1.
