Thoughts on this pump? When I was putting my new corals in my tank last night i realized there is a short some where. I got a little shock. So todays project is to figure out what is going bad. I have replaced most if not all of my power heads. So I am thinking its got to be one of the pumps.
Those are great pump. Maybe Scott will jump on here and let you know what he thinks about them. I know he was doing some research on them and I believe he has one as well. Not sure if it the exact ones or different ones though.
before you go replacing everything use a multi-meter and find out for sure what it is it can be anything even lights if close to the surface can give off induced voltage.
There are two camps on grounding probes, I am for them myself and I would rather have current being made and going to ground then stick my hand in and find out that I’'m the ground, just make sure you are using a GFIC.
Yeah I will look into what is doing it first before replacing anything.
Get a Gfci and a ground probe if it’'s enough to do harm it will trip. Were you barefoot when it happened?
I tried to get Jeremy to do it! I told him to stick his hands in there and will plug stuff in and he can tell me when he gets shocked! :
: He wouldnt do it. I dont understand why!!!
He said there are others way to do it. I said I know!!! He is no fun!
The Jebao line of dc return pumps seems to have 2 models. The first one is this:
This line was the first generation of the RLSS pumps, the rights were sold. Reef Octopus (Diablo dc), Jebao and Waveline all sold this line of pumps. They are identical, with the exception of reef octopus put a red plastic cover on the back. FYI: reef octopus is discontinuing this line, reasons vary on the nature of why they did this.
Here is a link on DC pumps: (you will find under the diablo line they are identical)
The second Jebao DC pump is the one you posted. It uses very similay technolgy and came out after the one I listed above. Unfortuneately I can’'t tell you much about it as far as reliability. The one you linked to is really big. You can turn the pumps down so look at the range of flow. 700GPH minimum to 2300GPH maximum. Will you need that much? You could save a few bucks on the smaller model.
I can tell you that I have a reef octopus dc pump, model 3500s. It has been good thus far. Its been running constantly since last September. I have cleaned the venturi 1 time as it clogged with calcium deposits. Pretty normal. It is extremely quiet and very energy efficent.
I am happy with DC pumps so far. I think I’'m going to get a RLSS generation 2 DC return pump for the 120, because it is Apex controllable.
I do like the price tag on the one you posted a lot better than the one I posted! I currently have a 90 gal but want to upgrade it to something between 200 and 250. So I want to make sure that it will work for the larger tank. Once I upgrade I will turn my 90 into a cichlid tank and my 55 into the refuge for the 200 or so !
The pump you listed would be flexible enough to do that. I would use a ball valve as you may need to run it at a little more than the 700gph setting to overcome head height pressure.
Will you be using it submerged or inline? Some of the smaller models you cant run inline.
It would be submerged. If I was to go with the ones you posted (price is a lot cheaper) which model would work for me?
The 8000lph (or 2113gph) is just a little smaller than the one you first posted. They do charge loads to ship it, to the door price is $108.00 I believe. I would do a search on the performance curve for that model (KM8000). That woild give a 220 just short of 10X an hour. Sounds like a lot but not really. Between 2 returns (1056gph) and head, elbows, ect., its not much. You could go to the one bigger if you are going with a tank bigger than 200g or running other stuff off it like reactors, skimmers, uv, whatever.
