Upgrading to 100 gal in summer, question about stand.

Kevman

Hey guys/gals, I currently have a woodshop class where the next project is my choice. I would like to build a tank stand for my breeding pair of Angelfish, and was wondering what I should use. I was going to go with a sturdy construction, 4x4's, with 2X6 cross bars, but my question is, should I pipe in a refugium, and wet dry underneath?

We have a Wet/dry, and refugium out in the office, and it really made a difference in water quality, opposed to doing weekly water changed, it's every 2 weeks. Also, in the event of a black out, what do you do to prevent over flow? A battery backup? And does any one have a similar setup with everything underneath, with a piping diagram? Thanks, KP.

OK I am going to answer this in the order you asked.
For your stand you can use just about anything from a 1x4 and up for size. The type of wood will matter as will the design of your stand. I made a cabinet stand out of nothing but 1x4s for my 90 gallon tank and it holds the 1000+ lbs of tank and water with no stress on it at all. I made sure that anything that is load bearing was connected to the ground with no gaps. the non load bearing parts could have gaps if needed.

Should you pipe in the Fuge. Well this is going to depend on your tank and fuge setup more than anything else. I have a corner flow tank with the bottom drilled. I have plumbed the whole thing (downflow and return) and added ball valves so I can shut off water flow as needed for maintenance or rapair. Even if you dont have a drilled tank you can still put a fuge in it and plumb it. I prefer plumbing over hoses personally it looks better.

In the event of a power outage I hope you have flood insurance... just kidding. I built the sumps for both my fresh water and salt water tanks. but both tanks have different overflow systems. First off is my fresh water tank. It is 90G and drilled (discribed above) the flow starts up on that with nothing special added just the way the down spout was designed. My sump for that is made out of a 20G high tank and I had to do a little math to keep the tank from overflowing when the power went out. I fist found out what the water level was going to be in the 90G tank after everything flowed back. LxWxH and calculated the square inches (volume). Then when I build the sump I made sure that I had the return area of the sump large enough to hold more than the volume of the 90G's return. so when the power goes out the tank just drains into the sump and fills it up and leaves me a few inches of extra tank, when power comes back on the 90G fills back up and the overflow will start on its own bringing the water back to the sump.

For my saltwater tank things are a little different. The same method of figuring the ammount of volume in the fuge was the same as I stated above. What is different is my overflow. I have a HOB over flow. This type uses a U or J tube to syphon the water out of the tank into a small transfer tank then into the fuge. This system works really good but if power goes out you need some method of restarting the syphon. I drilled a small hole in the top of the U tube and glued in a air nipple. Then I used an aqualifter pump to pump the air out of the U tube and restart the syphon. The Aqualifter type pump will pump both water or air. Some pumps will only do one or the other and will not work for this. This method is the only one I know of to successfully restart a syphon type overflow automatically.

I will look for the link to the pump and post it here for you when I can. and I will also post a few pics of what I have. I dont have them on this computer right now sorry.

Ahhh, I have been wondering about the power outage problem.. I was thinking about adding a valve that would close if there's no more power going through it, so it would close off the downpipe, and everything would be alright.. Do you have any pictures of your setup to the 'fuge?
