hot overflow? hang on back? if it is i would get the hang on prefilter from lifereef. it is excellent.. or u could make a pvc overflow. 1" pvc will flow 600gph,1 1/4" will flow 900gph or bigger if u need it. they are easy to make but not too pretty.

I would love to make my own...tight budget right now.
That being said, no idea how. I have made overflows for aquaculture ponds...but not aquaria. The whole power-outage/overflow scenario is a lot less scary when its your farm and not your basement.

Well the eheim that would be pumping the h2o back has a flow rate of 264gph...so maybe something around 250? I know that is incredibly slow...but the main goal of this fuge is to remove nitrates, and create tang food. (Several dehydrated macros + vitamin enrichment. Coming soon to MFK for sale section )
That being said, my only concerns are power outages ect...what happens then? I will probably end up frying out my pump.

I would look into doing an ATO whenever the cash presents itself. Its very nice...FLESHY;4499144; said:Well the eheim that would be pumping the h2o back has a flow rate of 264gph...so maybe something around 250?

Also, flow rate of the overflow doesnt have to match, just so long as it exceeds the output of your return pump. The overflow will only drain at the rate that water is being pumped in.
With that said, I dont know if you can throttle the return on your canister. If its a magnetically driven pump, you can put a ball valve in.
If you get a good overflow, the siphon will restart. The key is to never let the water level on the back portion of the overflow to become lower then water level in the front of the overflow, which is incorporated into the design of overflow. The actual bulkhead/prefilter assembly would need to be offset higher for that to work.
This is taken from lifereefs website. You can see how the siphon tube and acrylic plates reproduce this.
The eheim's flow are adjustable via the clamps that you use to remove the filter for maintenance...you can just close these as much as you want.
It will require some tinkering. I wanted to avoid buying a fancy overflow because that looks like it would run me about $60...and I have a hard time doing that for a couple pieces of plastic.

Good deal. Heath has an overflow that he might be giving me...maybe he can chime on the details of that...
In the meantime...is there an appropriate way for me to make a "fool proof" HOT overflow myself? I have experience with pvc fab sumping before, but only as a helper. As mentioned before I have also done it in aquaculture, but that isnt so high risk ect...If I make my own I want it to be well supervised by the likes of you guys to tell me how its done. Thanks

Yea, it's posted all over the internet. It's called the pvc overflow. More reliable and quieter than store bought ones
