For Those Who Use Rubbermaid Stock Tanks.....

Those of you who use Rubbermaid Stock Tanks for sumps, how do you deal with microbubbles? Do you baffle them somehow?

Any pics and ideas welcome. :)
 
If you can imagine a tee inside the tub with a small peice of pipe on each side, an elbow, two more small peices of pipe, two more elbows then tie those together to form a square. Now you cut a narrow slat all the way around that on the underneath side and have the water pull through it on the bottom of the tub, that should eliminate the bubbles or you can just drill holes in the bottom of the square.

I will try to post a pic. later if I can get one.
 
Overflows into the stock tank at the top, returns go out the bottom, keep the water level nice and high! No bubbles.
 
I didn't go to the LFS to take a picture tonight so I quick drew one.

Imagine this on the bottom of the sump and water pulling through the 1/8" or so slats, you can drill like 1/4" holes instead but you should get the idea and I should proof read before I finish a drawing :(

I thought this was confusing.

And then I saw this. :)

I use filter socks.


Can you eleborate on this? How do you deal with the bubbles coming from your skimmer? Any pics?

Use zip ties & hang the filter sock from your return line on your skimmer.......................
 
Filter Socks

Filter Socks

Here are some shots of my sumps. The sump on the left is 100 gallons and the sump onthe right is 75 gallons. They are joined together by a 2" pipe that you can see running between them behind the Deltec skimmer.

My return pump and skimmer pump (not pictured) are between the two sumps and behind the skimmer on the floor. The pipes coming out of the lower portion of the Rubbermaid sump feeds those two pumps. While it is not the most beatufiul set up it is effective. Here is how I have my filter socks, again it works. Just plain ole rubberbands.

The two pipes are obviously my return pipes from the tank. They main return pump feeds off of this sump. These socks eliminate all bubbles. My skimmer on the other hand drains into the sump on the left 100 gallon. There is no chance of bubbles getting into the 75 gallon on the right side, and into the return pump. Its hard to see but look at the sump closest in the picture, and you can see the water coming out of the skimmer (top Middle).

You can always put a filter sock on the end of the skimmer return pipe. This will also filter out what does not get removed by your skimmer. Just be sure that it does not restrict the flow, and cause your skimmer to back up. I hope this helps some.
 
I plan on using a stock tank. Not sure what size. I like how the 50gal is short to get stuff in there easy but I'm thinking that it's gonna be too short.

I built a sump within the rubermaid. A sump-in-a-sump if you will. this allows me to add filter pads, control water level much more closely, etc. Hope this helps you out.

I chose not to add a sump within the sump so I can have maxiumum water height in the Rubbermaid. I run an external media reactor made by MRC that holds phosphate remomver and carbon. Both of my sumps have caulerpa and cheatomorpha in them. They both have alot of live rock and the 75 gallon has some sand also. DSandFort your sump in a sump looks good. How high can you keep the water level, and still be functional with the other chambers? I think you may have issues with the drain line (if thats the line with the holes in it) being submerged? I assume thats why you drilled holes in it to let air escape and keep it flowing. Unless you are not running the water level very high which seems like a waste not to use the majority of its capable volume.
I did cut egg crate and made a shelf for frags on the left end of my 100 gallon sump. The Rubbbermaids are made with a make shift shelf holder already built in. Thats kinda cool. It looks like you maintain water volume at less than half way by looking at your plumbing.
 
LunchBucket you can easily make shelves in the Rubbermaid tanks with eggcrate. They already have a great support around the edges of them. Even though they are meant for re inforcement I am sure.
 
I have not got that far yet. I do have a Litermeter III that I have not installed yet. I know that my tanks evaporates approx 2-3 gallons a day. Seems that I could set the Litermeter to meter that much each day. I am not sure though. I have no experience with the osmolator.
 
Drummereef, I am sure you can make a bracket to use the osmolator. In my case the sump on the right is the sump that shows the lower water level. The one on the right stays constant. If you use just one sump it will not be constant, and the osmolator should work as long as you have a bracket to hold the sensor steady.
 
The flex tube with holes in it is for the skimmer feed. This design allowed me to keep about 2/3 of the tank volume in play. You could do more with a different design, e.g. taller sump in sump. By laying filter floss on the egg grate, I sure could polish the water.
 
I have a couple of stock tanks I am getting ready to plumb into my system until I heard of several "splitting". I have never heard of this, I know they are built tough, and made to hold water but on another site someone said theirs split? This seems very unusual, anyone ever hear/experience this??
