New Tank, Need Advice

[timg]

Hi folks, just found this forum, thought it was brilliant and could do with some advice from you all.

I am just about to build a new tank for my living room. It is the completion of an on-going project which I have been working on for a few months.

My living room is 15'x12' with one window and a door. I have three walls that are available for tanks, two of these are already completed, Click here, but I need to build in the third wall with a BIG tank. The dimensions are going to be 96"x16"x18". The capacity will be around 100 gallons. This will be added to my existing 48"x12"x18" tank to form a complete run along the wall.

The light canopy will be the same as with the other display and will house all the lighting, air supply and power for heaters etc.

I have a good air system already, so airation is not a problem, and most of my other tanks are air filtered as well, but I have doubts as to whether this would be sufficient for this size of tank.

My questions:
1. Filtration; what would be the best type of filtration for a tank of this size? (In-tank filters or external sump?)
2. Water Changing; I am aware of the python system, but am concerned about having pipes trailing across the floor with young children around. Has anyone built in a changing system that works with permanent piping, as opposed to hoses? (I have a similar problem with my other tanks, but they are much smaller and so there is a lot less water to change.)
3. Heating; What size of heater would I need to keep this tank warm? (I am using 150W heaters for all he other tanks, but again, don't think this will be enough.

Your input would be very helpful. Thanks.

1. I'd use an external sump
2. I've yet to find a simpler and/or more efficient device than a python. If you're concerned about kids running over it, duct tape a weight to the end of it to hold it in your drain.
3. Prolly a pair of 250watt heaters if you have weak lights.

Filtration > on a large tank canisters get pretty $$$ - I'd be tempted to put two smaller ones at either end - maybe a pair of Eheim 2217's or Fluval 304's. I've heard that a sump is better option, just don't have a lot of experience with them.

Water Change > go with the python - the effort and cost required for a more permanent system outweighs the benefit

Heaters > get a pair of 200w or 250w (it's just a couple of dollars diff) - but get the same kind - I;m kinda partial to Ebo's 250 and Rena's 200 Top-light (having owned a couple of both)
