cool thanks for the help Toddrtrex, i might just get that instead of glass,
but as mention above, he said not to use acrylic with glass, glass with glass and acrylic with acrylic, u have any problem with the acrylic with glass?
hmm thats a good point drillsar, dont want a flood in my house when im not home ROFL..
but i though the CPR overflow will only work when air is pump into the overflow. so lets say for instant i use a maxijet to feed air to the overflow box( with the maxijet air thingy), then when the power goes off, the maxijet goes off and there for no air into the overflow, so the overflow will stop sucking up water. right? does that make sense or is it confusing the way i put it? lol or maybe i getting the concept of that overflow wrong
