smallest wet dry for 210

[Bderick67]

Isnt the amount of biomedia more important than the size of the sump tank? You can have a 3ft tall tower full of biomedia tricking into a 20 tank. Your saying this wouldnt make a difference?

The most important thing with sizing the sump is that it don't overflow if power should go out. Depending on the footprint of the 210g, a drop of the waterline 1" in the tank is 7.5-8 gallons of water, there will need to be about 6 gallons of water continous in the sump to keep pump and heaters submerged. This leaves 6-7 gallons of overflow space, probably can be done but exact overflow placement is needed.

Also wet/dry design should submerge biomedia in case of powerfailure, this will make for a higher survival rate if power loss is lengthy.

i think a 55 would be great if you could get it...but really if u set up your tank so that the return line is at the right level in your tank that it totally fills up your sump...you will be fine...i have my 125 set up into a 29 gallon... and when the power goes out the sump is almost filled up...its a lot of trial and error...when u set it up...keep your return line high and shut your power off...see where that puts your water level in your sump at...if you have 5 inches of water, you can lower the return line....if you see its going to overflow your sump...u need to lift it up out of the water a little more.

good luck and im sure you will get it
