tank combining

[mypapercuthurts]

is it possible to combine two tanks to where fish could go to either like a hamster cages?

Yes it is. Check this out

Waterbridge

wow you could just make a bridge and would it have to be staight?

From what I can see, it doesn't need to be a specific shape. Since it makes a sort or vacuum effect when installed properly. The details on how to build one are there. Quick Overview

No Air in the bridge,
Cap the ends making sure it is water tight
insert the ends into the separate tanks
remove the end caps

If air is present i am sure you could use a bit of air line and suck it out like they do for standpipes and such...

the coolest part, is that if you have external filtration you can have the intake in one tank and the return in the other.

hmm to help with the mental picture .

Imagine putting a glass in a bucket of water. Now make sure the glass is filled with water. Turn the glass upside down while still in side the bucket. Lift the glass straight up and out of the bucket. It's not easy because there is nothing to replace the water with as it has no opening to air. If you tilt the glass sideways you immediately break the vacuum seal and the water drains.

WOW that's so cool, I think I might try it. Thanks for the Info

That's amazing. The only thing i would caution is that make sure the tanks are on the same level, or at least the water levels are the same or you would have a siphon from one tank to another. Which would be a huge problem if u had a 10 gallon that was lower than a 55 gallon and connected them both!

Theres a bar here in Brighton in the UK that has a couple of tanks in seperate rooms and then are linked with a bit of tubing like that, although it doesnt come in at the top like that one does.

Somewhere there was also a post of someone who built their own Waterbridge between two tanks and it went about 100ft across and 20 ft up. It was massive.

I seen a RTank Setup a long time ago where the 2 tanks were joined together with a Acryllic Tube about 3/4 the way up, it Was a Tube Joined together with 2 tanks and Put together using Water Tight Joints.
But I've NEVER seen one Like This...

Just ONE QUESTION THOUGH?
How do you Get O2 Exchange inside the Tube UNLESS, their is Some Sort of Pump to Circulate the Water?
Or am i Missin Something?

Now that is cool
Could use the same setup and one huge filter/sump to filter several tanks.

A somewhat extreme version of this idea can be seen here. We discussed it a year or so back. Seems weird to me!

too bad that the "Waterbridge" instructions were available for free at their website (I just bookmarked it then) and now you have to pay for it.

anyone ever see large clear pvc at the local hardware stores??

 

[Ryeguy]

I found some by calling around, but it can only be ordered in 10 foot lengths...

3 1/2" costs ~$150 CAN, and plus taxes likely.... for the ten feet

anyone local want to split the costs with me haha?

edit - i also found i could get an acrylic 4", for $40 CAN in a 6ft length, bit cheaper

just to be safe I would also leave as much water out of the tank as there is inside your tube for both tanks

for instance 5 gallon of water in the tube

if something goes a muck you dont want to find 5 gallons of water on the floor
