I agree that the tank looks fine and shouldn't give you any problems. The weight of a glasscages tank is distributed across the entire bottom panel, and not along the edges like most of the other brands (all-glass, perfecto, etc.)
I agree with your reasoning. The more water you get in your sump the better.I have a drain at the top of my sump (it's an acrylic 55, easy to drill holes). I put a 1.5" drain right at the upper side of the sump and this drains into the back yard, if there's ever a power outage. Then while the pumps are running I fill the main tank until the sump overflows into the back yard, then I have my sump filled to the max. One day while doing water changes and forgetting to turn of the water supply I noticed no water on the floor! The system is even full proof for me! No pun intended. I went the next step and put a drip system into my main tank and set it to 1 gallon an hour (24 gallons a day). I never do water changes anymore.DaveB;3181206; said:Can someone spot any flaws in my reasoning here?
If the power goes out, roughly 2 inches worth of water will fall into the drains before it stops and is below the lip of the overflow. 96x30x2 is 25 gallons of water. (Ish.) So I really only need to leave that much space free in the sump for an emergency.
If, using some rubbermaid garbage cans and ingenuity (like NolaGT's sumps), I'm able to elevate a bunch of my bio media another foot above the sump's top, I should be able to keep 1/2 to 2/3 of my media "dry" and still keep 80-90 gallons worth of the sump full of water, right? Most sumps usually operate closer to 1/3 full but I figure as long as the tank can overflow into it with some extra space why not have more water?
I'm trying to come up with a way to really put that 72x18 footprint to optimal use for media capacity as well as upping the total water volume closer to the 400 I originally intended to buy until I got such a deal on this tank. What would be really cool would be if I could figure out a way to evenly distribute the water over about 4 feet worth of drip plate. I guess since I've got that massive intake hole I could split it over two garbage cans. So basically I'd have a tower on either end and the pump(s) in the center, collecting filtered water from each overflow, almost as if it was two separate sumps. And I'd have 380 gallons of water working through my 300 gallon tank, which makes the fish that much happier.
