what kinda tank is it, i know one of them has a double wall, so it can drain from the bottom too. i think its AGA. is your overflow round or square? if its round, or if it has a double wall, you cannot, otherwise you are good. you could also just loop it up and over the rim of the tank.

Ok, let me through this in here . Instead of a closed loop I have decided to go with this product: http://www.championlighting.com/e/env/0 ... tunze.html
If you compare the costs I think you will find they are real close. If you compare the type of flow you get with the stream pump, they are quite different.

Well, those things are pretty cool. However it's still a pump that sits in my tank and requires maintenance, collects algae, heat, and doesn't look pretty. The option with two devices and the controller looks really interesting, but I have to hesitate because it's like a power head in my tank.
I ordered the 6110 from Premium Aquatics and hope to receive it this week. As you know Louey, no one hates power heads more than me , but if I can get away with using just this one pump, I think I can hide it. I will be sure to give a short review after I have tried it.

Drilling your own tank? Hmmmm. Man oh man oh man. If that is what you want to do....I love the DIY spirit, however in this case.....I have extensive experience with drilling glass tanks. As a matter of fact, I once drilled a glass sump for Eric Borneman when I worked at a LFS here in H-town. Hehehehehe....I cracked it. We got him a new one and I re-drilled it. Well, the place I worked at just had the diamond mandril bits you talk of. You use a suction cup ring or a clay dam to encircle the area you are going to drill. Next you fill the inner area up with a 1:1 ratio of anti-freeze to water. Then drill the hole slowly...backing off from time to time. When you start the drilling, hold it at a slight angle and hold the drill very firmly in your hands. Start the drilling at this slight angle until you make a small crescent shaped cut in the glass. This is to give the bit a hold. It is best to do this with one of those drills that has a level bubble at the top so you can see if you are holding the drill straight up and down (plumb). After the slight angle position has given your bit a grip on the cut...level off so you are now drilling straight down. Proceed slowly and don't push on the drill. Let the weight of the drill do the cutting. Go especially easy near the end so you dont just bust through the glass causing those scalloped chips around the hole. You may get some chips but just put silicone rubber on the mating surface where the bulkhead meets the glass. Wear safety goggles (I dont think any of us wants to hear about your eyes popping :twisted: ) just in case. Also...when you are drilling and almost near the end, when you think you are about to braech the hole, pull up ever so slightly on the drill and hold it firmly. I broke Eric Bornemans tank because i was pushing near the end and when the hole gave...the drill collided with the aquarium, cracking it :x . When I was doing this sort of stuff in Dallas, where most of my glass drilling experience comes from, my boss, Tom Hudson (who was R and D (research and development) manager for Oceanic Systems taught me using a Baldwin glass drilling press. That is really the only way in my opinion but I am sure that they are expensive. Look it up on Google.com. Anyways....please be careful.
I like your idea King about the overflow drilling but be sure that you secure the plumbing well to the wall or stand with those pipe clamp things. The ones at Lowes or Home Depot or the likes. You need to support the pipe well because over time all that vibration may knock your overflow box loose...draining your tank. Yikes. Think about it......tide out. :lol:
Take a look at the last baffle and I;m not sure of the demenssions but I think that you might not be allowing enough water in the last baffle for evaporation. Try moving the last opening a little lower or make that last chamber larger...
I have the same baffles set up more or less and it allows for about only a gallon for evap....
