55G drums to add more system volume?

I'm in early construction of a new in-wall 120. Just ordered my custom Envision Arcylics tank (yes!) that will arrive in about a month--so now I'm committed!

I'm plumbing down from 1st floor to basement where the 75 g 'fuge and 30G sump will be. I'm planning on running the overflow down to a T and a ballhead where I can regulate some of the overflow to the 'fuge with the rest going directly to the sump.

I did a bit of concrete work in my basement and have some exposed soil that I'm thinking of placing 2 food-quality plastic 55 gallon drums a bit in the soil to help facilitate heat exchange and to add more volume... so these things would get 100-200 gph from the overflow I'm thinking along with the fuge that all drain into the sump.

I'm wondering, though, if it's a good idea to put these large, dark vessels in my system. I'm thinking they would act as a settling tank to a large degree... could I be creating a ticking nutrent time-bomb? And what might eventually grow in there? and might I need more water movement in 'em?

I'm also wondering if having say 200G of water in the basement may help with heat exchange to the point where I don't need a chiller. . . I'm not planning on buying one off the bat but will budget for one should I need to in August.
 
yould always vaccuum the bottom of them you could also do your water changes in the drums, or like you said for cooling you could put a fan on top of one for cooling
 
I say go for it. The large dark vessels will grow lots of sponges and other filter feeders which should help clear the water and grow lots of pods. You will also help with your system stability by significantly increasing your water capacity...
 
Great idea about doing water changes by siphoning out of the drums. That way I clear out the settling stuff b4 it gets out of hand (that is if I keep up on my water changes ;-).

I have lots of room in my basement so if the 2 55g drums work out maybe I'll add more over time!

What do you all think about flow rate? should I go for less flow (like maybe 100gph) to encourage the settling aspects?
 
or just drop in a QuietOne 3000 in the bottom of each drum. to help with water movement and keep any junk in the water column.

I agree, actually I am considering dropping a powerhead down to the bottom of my overflow just to keep things from settling down there too. I have standpipes in the overflow so anything that sinks too low in the overflow never really has a chance of getting out.
 
I'm a bit concerned about putting a RDSB in a 55G drum. I'm planning on a RDSB in a 5gal bucket, but my take on a RDSB is that it is better to be deep because of the anoxic factor. So a foot deep or better smaller bucket would be a better denitrifiactor.

I'm in the process of reading A.Calfo's long RDSB thread at the moment (man it's long!) so maybe I'll change my mind. But I would think that if I did a RDSB in a 55G drum that I'd want it a foot deep...not an inconsequential amount of sand and $ for a west-coaster who can't buy southdown cheaply.
 
Yes allot of sand would be required to do it and not practical, but I still recommend trying it in a 5g bucket, im in the process of making one myself.

And remember what calfo said earlier on in the RDSB thread, a LFS had a 55g tank for a RDSB and that was sufficient for a 2000 system. So as i said not practical but you wouldn't have to get a new for a while...;)

And for the system you have a 5g bucket should be fine.
