Thanks, I really like the surges. I would consider going to 1.5" line to the tank if possible. If not I would split it to 2. Trying to feed that much water through a 1" drain will take a while. My surge takes about 45 seconds to drain and it is around 6-8 gallons.
 
I finished off my auto top off system last weekend. I am using a reef filler pump to pull water from a 40 gallon ro/di storage container. It feeds the water to a reeftek kalkwasser reactor and then into the sump. So far it is working very nicely. Here are some pictures.

Those surges are great... I think I'll incorporate them into my 240. I was going to go with 2 K8s on a slow timer, but instead I think a 55 gallon dual surge would work great.
 
Thanks for the compliments,

If anyone has specific questions regarding my surges or a recommendation on how to do them on your tank feel free to pm me or post here.
 
I don't have a sump on my 240. I want to do a 20-30 gallon surge (or two) but I'm concerned about the DT water level raising and lowering. I want a tidal effect that would fire off one surge slowly, maybe once every ten minutes.
Two questions - are two 20-30 gallon surges ridiculous overkill? Would two ten gallon surges be more reasonable?
Any idea on how to keep the DT level reasonable without a sump?

I think that it could be done but you are going to have to keep your water level lower in the tank. Depending on the footprint of your tank you can calculate the water level you would need to handle the surges. In my tank the water level sits around 1-2" below the eurobracing on the tank. When both surges fire at the same time the water level rises to the eurobracing.

The amount of water in the surge is not as important as how high you have the surge above the tank and the diameter of the pipe feeding the tank. The amount of water in the surge will control how long the surge fires. I personally like smaller more frequent surges then on large one. It can be done either way.

What are your tank dimensions?

It's a standard 240 - 8x2x2.
I can have the surge tanks pretty high, around a foot or two higher than the top of the display. I was thinking of using 1 1/2" plumbing to prolong the flow, but I hear that may be too small.
I've got to keep the display water level above the bottom lip of the canopy. I might have 2" of water to work with.

At that level your tank will only be able to handle 15-20 gallons of water. My surge tank sits 16" above the water level and I wish I could get mine higher. The other factor to consider is how deep the surge inlet to the tank is. The deeper it is in the water of the tank the higher the surge needs to be in order to fire. My surge inlets are around 3" below the water level in the display tank.
 
After seeing the simplicity of the surges, I think on my next build. I will plumb some surges in an upstairs closet for a good pressure head.... Keep up reefing

I picked up a rose anemone last week. My maroon clown are loving their new home already.

I have moved over all my corals to the new tank. I still need to move over my tangs and trigger. The plan is to move them this weekend.

Here is the latest aquascaping
