Surge tank experience?

Yeah I guess it would be like a toilet lid.

Speaking of lids he talks about a forced CSD where the top is sealed with an air vent with a check valve to build up pressure so you can use a bigger output pipe. But it's on a 100g reservoir with 4" pipe.

I was thinking of trying at least 1.5" to 2" for mine for maximum flush velocity. I hope that size will work.

Also, I was thinking of using a Maxijet 1200 to fill it up to the 3.5 gallon point. (approx 45 seconds)

As long as it doesn't fill so quick that the siphon doesn't break at the end of the cycle. Then it just goes up and down without completely emptying or filling.

Again I have no experience with these, I'm just passing on the info.
