No, my tank is not drilled, thats why I am excited about the over flows I have seen on here made of pvc pipe.
The tank I have is a 20 gallon long. It was given to me,it already has baffles and all.
Sounds like the mag is a good deal then, I just wish I could figure out the plumbing for it. Thanks and no one else can help me out here? No one?
Hmm, I believe you are going to run into a water volume issue with the 20G.
Since you have a 110G DT I will assume it is at least 5ft long. When you get it set up you will have the return nozzle in the DT. When the power goes out it will suck water back out of the DT and into the sump until the nozzle gets below the water line and breaks the siphon. So you have to leave about 5 gallons of empty space in the sump. You could certainly try but I would aim for a larger sump if you have the room in your cabinet. It doesnt even have to be anything fancy. I made a sump out of a garbage can one time.
So, what you will want is the HOB overflow system. One of the CPR style ones. There are several look alike ones out there now but just make sure it is the kind that has two chambers on the back side of the tank. This way you can keep the U-Tube below water at all times. Keeping the U-Tube below the water will make it keep its siphon so that if the power goes out it will keep siphoning when the power comes back on and you dont get water all over the place. The water should come out of the HOB overflow through a bulkhead. I would connect a piece of 1" flexible tubing to that. Just need to make sure the tubing will be long enough to go from the overlow down into the sump a good distance. If you keep the end underwater going into the sump that will help reduce the gurgling noise. Since you have a smaller sized sump you could get by with a pump that does around 600GPH. You could use the same kind of flexible tubing as the overflow. Then for the end that goes back into the DT you get a hang on nozzle. I'm not sure if they have an official name or not.
This is the pretty basic set up. You could ultimately get more advanced and use PVC pipes for all of the plumbing. If you get a bigger sump I would consider doing this. With the smaller sized sump I think it would be good experience to go with the flexible tubing so you can get a good idea of how the whole system works.
Hope that helps some. Didnt mean to write a book there. But on the other hand if I help keep water from getting all over the floor then it's all good.
Best of luck with the set up.
