I have a 29 gallon DT and I have been told that with PWC
done weekly, I don't need all the extra machanics that a larger tank would require. But I plan on having a larger, built into the wall, SW
tank as soon as I feel I've got the groove of this hobby. I'm the type that has to see it and do it, to learn it. Since I don't have anyone to show me how things are done, connected, arranged or how it helps here in my area, I'll have to do on my own until I get it right. This being said, I'd rather learn on my 29 gallon and not wait for the bigger tank.
I want to start with a refugium and since it's just a refugium, I don't want to redo my DT case at this time. I have a shelf over top of the DT that I'm going to put a 5 gallon tank on as my refugium. I'll have a pump inside my DT to send the water up to the refugium and a over flow to send the water back to the DT.
Now at this point...my questions are:
1. If the power goes out, will water from the refugium syphon back into my DT (flood) or will the pump stop that from happening when the power is off?
2. After I have the refugium set up and I'm doing PWC
, will I take the water from the refugium or the DT?
Here is a picture of my DT case right after I bought it, so you can see the shelf...the 6 gallon is no longer there. I moved it to my kitchen.
