This tank is awesome and so is the CO2 reactor! niiice.
If you want to insure that the siphon holds, install a airhose nipple at the top of the first U bend and run an Aqualifter(<$20) back into the main tank.
The plant looks to be wisteria grown under low light conditions.
Can't wait to see the carpet grow out.
That is a good idea but mostly I see these (aqualifters) used on overflows with high GPH. Mine being a drip water top off would be flowing at a rate of .29GPH and the aqualifter is rated at 3.5GPH. So it would be sucking more air than water. Which would make me worry about maintaining the vacuum in the U tube on the outside portion of the aquarium. Maybe have the aqualifter on a timer for only a couple minutes a day?
Edit: OR have the U extend slightly longer on the outside of the tank and raise the tee for the gas off pipe so that would make sure air is only sucked through the tube inside the aquarium.
So without having to spend a ton of time filling up gallon jugs to figure out my required drips per minute I used a test tube and some math to get me at least close. According to this site I need to add 7 gallons per day to equal a 47.97% water change per week.
My test tube holds 5.8 grams of water
To achieve my 7 gallons per day I would need 26497.9 grams or 4568.6 test tubes.
So my target should be 1 test tube filled in ~18.9 seconds
Any uber geeks out there feel like double checking my conversions?
