View Full Version : Building my own Sump, could use some advice.

02/15/2006, 11:30 AM
I have a 29 Gallon tank that I would like to build a sump for. The only thing that I can fit under the stand would be a 10 gallon, and that is going to be a tight fit.

Is there anyone out there that has built a sump before that would be willing to give me a little help? I have two designs. I came up with this one first:



I liked the idea of the crash chamber being a little higher then the sump area that then pours into the fuge area. The only problem I thought of was bubbles from the crash chamber going into the powerhead for the skimmer. Would that effect the operation of the skimmer?

I changed the design a little and was wondering if anyone thought that this was a good/better design:


Does anyone see any problems with this design? I sort of like the first design better if the crash chamber isn't going to interfere with the skimmer, I'd just really hate to get it built and then find out I have to rip it apart. :)

Here is an idea and it is a pretty simple design.

WIth the picture above, i didnt mention a few things. The Divider on the left should be taller than the divider on the right and the divider on the right should only have grooves halfway across, otherwise you will have bubbles returning to tank.

Check out this link. The guy has a tremendous amount of experience and insight when it comes to building sumps.

Thanks Spoke, I have checked that page and it is great. I just haven't seen anyone do it exactly this way before and wanted some advice.

I am starting to lean towards this design here:

Be carefull with a small return area if you don't have an auto-top-off system, as you'll be topping off very frequently.

Yeah, I think I have been convinced to add an auto top off. I just ordered the float switch this afternoon.

Now I just need to figure out what I will use for a container and where I am going to put it.
