Air System Upgrade

Bob,
tested the backflow problem and it isn't happening. I think the main reason it doesn't happen is there is at at least an inch of space between the surface of the water and the top of the tank.

Don,
Good to know on the AC's. Sponges keep my tanks pretty clean and clear. Anyways I do try and move an AC or a Fluval 2+ around between tanks once in a while.

Nice setup!

You're not saving that much by ditching the Aquaclears, though.  AC110s may use 14 watts for the first fraction of a second when they're just starting up, but once they're running they only draw 7 or 8 watts.  I measured them and posted my results in the Electricity Consumption thread .

Running two AC110s on a 75g sounds like overkill, but you might want to keep running one of them.  Air-driven sponge filters are great for bio, but do a lousy job at pulling particulate out of the water.  I usually run a sponge plus some type of power filter wherever I can just so the water will look nicer.  Often the power filter is way smaller than the size recommended for the tank- it doesn't take much if the intention is just to keep things stirred up and pull the visible gunk out of the water.  

My current favorite power filter for the job is the Whisper 10i after it's been converted to run on Poret foam .  Works great in tanks smaller than 30g- I even have one in a heavily populated bare-bottom 55g along with a big air-driven sponge filter.  Even in a tank that big, it makes things look pretty decent instead of downright filthy.  

I just tested seven of my converted Whisper 10i filters to see how much power they consume.  Four were using 2 watts, two were 3 watts, and one bounced around between 2 and 3 watts- my meter doesn't read fractions of a watt.

I have the exact same air pump Shawn. Got it connected to a 15? valve manifold with about 10 in use.  Each valve has a "t" running to each tank. Some tanks have 3 sponges in em. Plenty of power left over.

My only issue with your set up (and I don't even know of it really poses a problem) is that you have the pump and manifold below the tanks. In the even of a power failure, you could be at risk of water back feeding down into the pump.

So for Christmas my family wanted a list of things that I wanted. On the list I had a new central air pump, couple of heaters, a few new sponges, and a couple of manifolds. I got eveything I listed and decided today was the day to upgrade the central air system in my fishroom.

Old air system used a Super Luft Pump and a DAPMH15 from JEHMCO (Thanks Kegger). New pump is a DAPPH30 from JEHMCO. Old air system was kind of a mess and completely unorganized. There were airlines and power cords all tangled up and it made for a troubleshooting nightmare! The other problem was I wanted to add in my 75gal tank, but the Super Luft Pump was out of outlets and I had maxed out the DAPMH15.  Here is what I had to deal with:

Old Air System


Old Air System2


As you can see this is a real mess! The new air pump is a DAPPH30 from JEHMCO:


Decided to do things right and make a small ring out of the manifolds and here is the piece of plywood that I mounted the whole thing to:


These are the the 6 valve manifolds that JEHMCO sells. I got 2 new one to add to the one that I already had. When you get multiple manifolds form JEHMCO they will make a basic ring or "Y" connector to fit the pump you are buying. I had to modify the "Y" connector into a ring system. No big deal just had to go to the hardware store and get a few parts.


Air Ring:


Got it all put together and connected to the pump. I really like the organized look to it. This is all mounted inside the stand to my 75gal tank.


Added all the outlets and labeled them so they are easy to locate if needed. I also added in three outlets for my 75gal tank. This is a much neater and organized setup,  Plus I have a few extra valves that I can connect some other airlines to if needed.



Power Savings
Old air pumps
DAPMH15 - uses 18watts, Super Luft Pump uses 35watts, 2 AC110's on the 75gal that are being replaced with sponges use 28watts together, for a total wattage of 81watts. The new DAPPH30 uses 40watts for a savings of 41watts, and $2.44. While not a huge savings it is savings and not adding to my costs which is good in my book.
