Iam wanting too set up a mini rack, for breeding tanks. When iam finished, i would like to have 6 tanks (29gal) run by 2 filters. There will be 2 rows of tanks, 3 each row and each row will be run by a filter.
Ive been thinking about this for a while and the main decision came between that being that all 3 tanks run off the same filter, there is the chance that desease will spread throughout the tanks. I have since decided that if maintaince is maintained and care is taken then is just as much chance of spreading desease then using the same equipment throughout the tanks ie. nets etc.
One thing i havent put into the system yet, is how iam going to do water changes. This is not because i dont have any ideas its more that i havent had time to put them on paper, this will be mainly the filtering of the tanks.
Ok here is a front on view of the stand.

Just some explaination - The timber used will be 90x45mm F7 structual pine, I have used this on my previous 3 teir 4x18x18 stand and with a good layer of paint is nice and strong and easy to work with.
Next, this is a diagram of the overflows and continue too the tank.

Ok the PVC pipe used on the over flow should be atleast 20mm so it can fit a pyhon tube in it and allow water too move back up and down the overflow too the sump. Although 20mm+ might not be practical for the whole setup, I can convert it too a smaller size after the actual overflow. The postion of the 'T' pipe is important as this sets the water level in the tank. If the water raises above this level then it will go through the pyhon tube into the overflow and down into the sump. Because both ends of the phyon tube are in the water if there is no water being added too the tank then the phyon will remain, although not pull water and once the water is added again it will once again be taken into the overflow.
And the same for the top row -

Here iam showing what i call the "Foam Tower" that will be connected too the sump. Basically this is the mechanical filtration, it will have a 1-2inch layer of sponge which i can easily remove for cleaning. The rest will have filter wool for any other solids and also some biological filtration. I have added some egg crate too the bottom but this might not be necessary.
This is from the sump toothe bio-filters.

From the sump the water is pumped back up too the top of the rack, there will be 2ft tanks which i call the bio filters. There will be a drip plate at the top to get a even spread over the bio media. Then a nice layer of bioballs and ceramic noodles. I will then put some egg crate at the bottom too stop the media being sucked down the out take or blocking it up. Once the water has passed this it will be taken to each tank. I will put balls valves on each pipe to control the amount of water going into each tank.
The last thing i want to do is too have the outlet for the filter (the one coming from the bio-filter) to be in one corner and push the water to the side of the pyhon so any feces or most will be sucked out and into the over flow.

Still alot of planning too do but this is the basic design.
Any comments would be great..
Thanks
