135G Powerhead Suggestions

[Jay-Hawks]

I'm currently rebuilding my 135G mixed reef tank from scratch and one of the upgrades I plan to make are to my power heads. I was running a read sea wave maker and 4 maxi jet 1200's, needless to say this wasn't the optimal setup.

I have an Apex Lite controller and I plan on using that to control my new powerheads and my thought was to get two 6105's. Here is my shopping list:

Qty Description
1 2-Channel Apex to Stream cable
1 Apex VDM module
2 Tunze Stream 6105
2 Tunze Safety Connector
1 Battery
1 Battery charger

Does this sound about right?

Another couple of questions I had were can you place the outside magnet on the inside of an overflow box? I would do this for two reasons. First, my canopy doesn't allow for a lot of room between it and the glass and second by placing the mount on the side of the powerhead it would reduce the visible footprint. Another question I have is how high on the glass would I want to mount the powerheads? My tank is 24" tall and I would prefer to mount them higher so you wouldn't see as much of the power cord.


Thanks.....


If you want to see my progress on my rebuild I have posted a couple of videos on YouTube

I think your plan sounds fine, to run two 6105 at 12V for 1hr will require about 2.1 Ah of battery capacity, I generally prefer SLA batteries as they are much safer for indoor use, this is the same type of battery in a UPS system, a household alarm, or a Power Wheels toy.

Both halves of the magnets are identical and waterproof, the newer stock 6105 magnet is ferrite and is exposed, this is the same magnet most impellers are made out of and unlike rare earth magnets does not corrode, they can however pick up bits of iron which will corrode and stain the magnets, for example they pick up a staple or some steel wool or iron filings on a work bench.

I would generally place the pumps 6-8" from the surface.
