In this photo we see the upper bearing, this part is the most frequent cause of a problem, it can become cemented to the magnetic rotor with lime, the magnet should spin freely on the bearing. Here we see the complete assembled unit removed, the bush bearing is not shown in the photo, the bush bearing is the collar that is around the impeller well. This drive unit is the same as the 6080.60 used on the current 60 pumps with the exception of the 7400.610 o ring. This drive unit is used on all 6000/61 and wavebox pumps made prior to January, 2006.
We will start with the 6100.60 drive unit. Marc Levenson- Melev here on RC, sent me some much better photos and I am updating this thread using his photos. Some of you may recognize that this thread was posted earlier. Now, lets get down to the pump and cleaning it. At the coral polyp the xoozanthellae remove CO2 from the water by photosynthetic activity, this does the same thing, the pH increase and CaCO3 precipitates and is added to the skeleton. Pumps vary in this effect, most pump have an internal temp of 4C over ambient, a Stream is about 1C. Inside a pump we have both heat and vacuum, by Boyles law we decrease the solubility of CO2 and the pH increase in a local zone this precipitates CaCO3. Why do pumps become jammed with Calcium? The answer is simple and it may surprise you to learn the same thing happens in your pumps as happens at the coral polyp when skeleton is laid down for growth. Just work on balance and stability, nature has more experience than all of us. They do grow fast enough and the idea of the Optimum Aquarium from Dupla applies to all aquaria, you will always have a limiting factor, by raisng the calcium you only changed it to another element be it light, flow, KH etc. Do my corals grow as fast as 500 ppm- no. By doing this my pumps only need cleaning every 6-9 months- 9 months is pushing it and I wouldn't recommend it. A high KH has also increased the availability of the Ca. I run a slightly higher KH because the KH is more critical to the stability of a closed environment and corallin algae responds favorably and many green algaes negatively to this higher KH. I have the advantage as a hobbyist of modern technology keeping the levels reasonably constant as well.
Why do I do it this way and not keep higher Calcium levels? First of, the reefs are about 380ppm Calcium with a KH of 8, they have the advantage of trillions of gallons of this solution passing over them. For salt I use hW Marinemix (hW Meersalz in Europe). I keep the KH at 12- I use superbuffer dKH from Kent if necessary. In my personal opinion I keep my tanks at about 380-400 ppm Calcium, I don't use magnesium or strontium supplements (any supplements except kalk and a calcium reactor for that matter). The pumps vary in the frequency they need cleaning with the habitat they are used in. The electronic Streams have a safety feature that sound an audible alarm when the pump is jammed.
TUNZE WAVEBOX 6260 HOW TO
Other than that it's a puzzle how to identify the problem, and if you do the only solution is a complete new transformer unit when all that's needed is a cheap capacitor.īTW the voltmeter is really a great gadget - inexpensive and brilliant at identifying stray voltages in a reef.I hope this thread will answer the most FAQ. There's no obvious sign of failure but the transformer didn't get as warm as it should (since no current was being drawn). That meant sometimes the pump started, sometimes it didn't. I'm not an electrician (shame really it would be useful) but if I had to I guess I'd say a capacitor in the transformer was leaking so the initial surge of power necessary to start the pump wasn't always generated. But somehow the transformer failed to peoduce enough peak current to start the pump consistently. The red light still lit up and the output was still OK at 18v (17.96v on my voltmeter). The transformer (6101.240 - now replaced by another model 6105.240) had failed. Other RC users might benefit from this so. Well after a few more intermittent failures to start the 6105 I've eventually figured this out.
