What's a NURCE?<a href=showthread.php?s=&postid=7381352#post7381352 target=_blank>Originally posted</a> by bigdaddyadam
I use 3 tsp. of calcium hydroxide to 5 gallons of water, even after letting it sit 24 hours before it goes into the NURCE, I still get a decent amount of settle out in the refiller, but it has never been a problem and since I started using the NURCE and refilling with all kalk water, instead of just a kalk drip, coral growth has exploded
I see the design on the page,and it is simplistic-but I see how it works. My question is, I don't understand why they don't make it anymore...Just this company ?<a href=showthread.php?s=&postid=7489413#post7489413 target=_blank>Originally posted</a> by bigdaddyadam
it's a level controller, uses suction and siphon to replace evaporated water in the tank...like a float switch but no electronics, kinda

they don't make them anymore, I got mine off e-bay, but even there you are lucky to find one. it works really well for my tank. I have seen plans for and tried to make my own before buying one. but it is hard to make one that is air tight, so I just broke down and shelled out the cash.
one good method that I hear works is getting a large glass bottle, the 5 gallon kind. get a rubber stopper that will fit in air tight. make two holes that are just big enough to jam tubing through. you must use tubing that is pretty rigid, not so it won't bend, but so it won't collapse under suction. one tube goes almost to the bottle of the bottle the other is near the top above the liquid level, both ends outside the bottle go in tank. fil the bottle with water. put the end that goes under the liquid level in tank first. then blow in the other tube. if it's airtight, water will be pushed up the first tube and then place the other tube in tank also at desired water level. i will fill to that line then form a statis equilibrium. when the water level drops the second line loses suction and the first line fills the tank with siphoned water to the level, at which point it again reaches statis and stops.
this will maintain the water level and keep salinity the same at all times.
I agree- I kinda hate to depend on electricity for everything on the tank, this would be such a viable alternative.[
as far as I know it is the only commercial product of it's kind. float switchs will have the same end result, but I don't trust mechanical devices all that much and so I opted for a non-electrical method that was less likely to end in catastrophic failure.
