Tired of Unreliable Jebaos -- Looking to Trade up to Tunzes

[TylerHaworth]

I say do an MP40 on each end and a pair of 6095's on the back wall.


EDIT: Oops, missed the part where you placed your order... The larger Tunze pumps will serve you well I'm sure!

Thanks. So looks like the "safety connector" is part of the battery backup system? I'll definitely be looking at these add ons.

Yes, this is one way to do it that's a bit more efficient than the alternative. But if you wish to add power back-up to additional equipment, like your return pump, you can get an inverter/charger with an auto transfer switch, and however many deep cycle marine batteries you wish (with more batteries giving you longer power backup). The price for an inverter/charger varies with the unit's max power capability and whether or not it's a "pure sine wave" inverter, but an inexpensive one that'll supply 1000 watts of pure sine power is about $300.

The key to the Jebaos is constant cleaning. Every 2-3 months they have to be cleaned. Power supplies fail, so I imagine a lot of blame is put on Jebaos when in reality many cheap power supplies are only going to last a couple years. I wonder how many Jebao pumps have been thrown away when the power supply could have been replaced. I also imagine that's one of the reasons they have a cheaper price tag because they use the cheapest damn power supply they can get their hands on.

I missed this post. When you say that power supplies may be causing Jebao pumps to fail, what do you mean by power supply?

Thanks.

. . . . IN my tank, all 3 pumps face the same direction and blast down the 8' length of the tank. When the surge hits the far end of the tank, it springs back towards the pump in the off cycle and it gives me a terrific back and forth surge that makes my corals dance. On that thought, two 6105's or two 6155's on one end of the tank (1 up higher and one down lower) shooting across the length of the tank would make for a real nice back and forth surge effect with them synced together and the right on/off frequency. Or you could have them on appoint sides and have one off while the other is on.

I was about to post to ask for recommendations of where to place the pumps, and then I remembered you already addressed this.

I will definitely start with pumps on same side and see how this works.

He means their cheap AC Adapters. I have a local friend/ neighbor (also a forum member here) who actually had one catch fire and melt right in front of him on his desk. Had he not been home, it likely would have resulted in a house fire. That said, while the Jebao's have crappy power supplies, that's not their only issue. They have particularly weak motors and smaller magnets on their impellers which is one of the reasons why they need cleaning so frequently to keep them running. It's also why they stall so easily. Especially when compared to the Tunze's that will take all sorts of abuse in terms of neglect and the Tunze's never stall. When you get your Tunze's, I am sure you will immediately notice the weight difference between the Tunze and the Jebao. The Tunze's make the Jebao's feel like toys. The Tunze's have much more powerful motors with heavier impellers which results in much more tolerance to neglect.

Your not saveing much buying a jebao then if you have to buy the pump then buy a more expensive power supply. Then you still have the issues that slief pointed out, weak motor, ect. But it still gets me when you add in all those factors the people still say tunze's are way to expensive.

Got my "heritage" package of 2 x Tunze 6155 Stream Pumps and 7092 Controller and could not be happier. As Slief recommended, I have the pumps on same side of 180. One 6" below surface; the other 6" below and slightly to the side of the other. Great wave action. Great flow without plowing up substrate or directly blasting any of my SPS colonies. Obviously too soon to compare with competing brands, but so far so good.
