Tank Layout, Pumps & Corals???

yachtdr22 · 04/06/2012, 11:47 AM

Greetings all....

I am seeking advice on a few things:
1) Coral Placement; I am trying to make sure that all of the pretties are set with the proper lighting and water flow.
2) The placement of Powerheads in the Tank; I have been following the conversations about stray electrical currents. I have measured over 50VAC between Ground and Tank. I have found that the contributors are all of the pumps that are not grounded (3 wire plug). I am considering buying a Vortec MP40. but i am not sure of the other circulatory needs?
Currently, there are 2) Hydor Koralia 1400 (one on each side facing the front of the tank at the top and 1 Hydor Koralia that is about 400gph (Koralia 1) that is on the Left side also facing front, but lower in the tank.

My hopes are to remove the sources of the stray potential. If I need additional circulation than the MP40 will provide, what are the recommendations for replacements that are grounded or are 12v the way to go??

Please note, all of the swimming critters are in HT / Hypo for Ich....

Thanks all for taking the time!!

Anyone?

If you want to remove most potential voltage you will need to remove everything with a cord from the tank. If you want to eliminate stray current you need to find the faulty equipment. If you didn't know there was a difference I would research grounding probes. Those arguments will provide you with all the info you need to make an informed decision about the numbers you are seeing in your tank.

Koralia's have a long history leaking voltage but it could be anything. Can't help with placement or proper water mover replacement as I am currently guessing at the tank dimensions and I suck at guessing. :-)

the tank is a standard 125 gal 18h" x 22t" x 60"l

Happy Hoppy Day!

60" would be about 100 gallons, 72" with those dimensions would be a normal 125. It is a little on the light side for a mixed reef. You won't notice it much until those corals fill in, then you will really notice it. A single MP40 won't adequately cover a 6' tank, they have really broad flow but in conjunction with the Koralia's it would be a lot better. For a mixed reef, figure about 30-40x tank volume for flow. A Tunze 6105 might be a better choice but a pair of them would be ideal. The hard part of getting flow in a standard 125 is it so narrow. I fought that battle with my old one and even with about 9000 gph there were times I wish I had more. Rock placement comes into play here as well, I had the usual wall of rock back then, which added to the problem. If you have a low aquascape and plenty of area above the rock, it gets easier to do, but MP40's aren't a good choice only because of their broad flow and the narrow depth of the 125. You have a nice looking tank, the corals look fine as well, but as time goes on, flow is going to be a problem.

As far as placement of equipment and corals and stuff, no matter how much advice and research you do your gonna move stuff around all the time. Just fell it out and do what works best for you.

Must have been too many eggs this weekend... Yes, it is 72" Wide...

Thanks for the feedback. I may need a little help in rethinking my rock work if it will help the health of the tank via better water flow?

I noticed I failed to mention the the current heads are on the wavemaker setting on a RKL. they run alternating 5 min. Left / Right.

Thanks again!!

You were right... Went with the vortech's with hopes of creating a nice wave surge and looks like i could do with some Re-Rocking.

I have been reading threads all day and have not come up with anything good,.... still looking for input!

Swimmers are on week 4 of Hypo
