Cracked Power Cord

[pscheel]

Hi Roger, I have a cracked power cord on one of my Tunze 6000. It is right where the cord enters the pump and is in water. The inner wires are still coated. Is this repairable or is it time for a new pump? Thanks.

Would say there are many temporary fixes, but would get a new pump.

I agree with nuttyd, I would replace it, what tends to happen is water wicks down inside the cable to the driver, it is a capillary action and it may take a month or more, but it will happen.

Thanks! Now I'm looking to replace it with the 6095 for my 90g sps/lps tank. It looks like they come with a controller now. I already have a 7095 multi controller so I really don't need the one that comes with it. Can I just purchase the pump separately? In between jobs so I am looking to save a little money.

The price did not increase when we added the controller in June and you can simply set it to external and use another controller. You might be able to find older controller less models on clearance.

Thanks! One other question. Would 2 of these be sufficient for a standard 4' 90 gallon tank or should I go with the 6105's. Thank again.

I generally recommend the 6095's for tanks up to 120, the 6105's are best for 180+

I got the 6095's hooked up to the 7095 controller however, I want to use sequence 2. Instead of the low pump running at 30% like it did on the old pumps, it does nothing. Is this normal?

You need to calibrate the speed range on the pump. This sometimes comes up due to a difference in the signal on older controllers. The procedure is below, it usually is fairly easy, occasionally a pump is off by more and a few attempts are needed.

1. Connect the 6095 to your 7095 controller
2. Please turn your 7095, to the minimum power of 30% on both speed knobs for the channel it is connected to.
3. Turn the 6095 to the external mode (yellow LED lit).
4. Turn the "pulse power" dial to a middle position
5. Hold the Foodtimer button, watch the dial on "pulse power" until you see a short flash of the blue LED continue to hold the button.
6. Turn "pulse power" until the 6055 starts in the minimal range.

If this does not work, what has worked best for me is to then find the minimum speed on the 7095 that the 6095 will run on, set the speed a little below that, so if it runs at 60% try 50% and repeat the calibration so it runs at 50%, then repeat slowly stepping it down in increments of about 10% until the pump starts at 30%. I have had it take as many as 7 tries but usually it works in 1.

Thanks! Worked 1st try. You're the best.
