I am really wanting to get my tank sorted out but I need to make a decision on plumbing.
Quick background, my tank is 6ft, the 2 holes already there are in the top left and right hand back corners of the glass (not on the bottom). I have opened them up and they are 40mm wide.
I have been to my lfs and he has said it would be much better to run 2 outlet pipes. I am struggling to see the real benefit of this. Basically the tank connectors are going to be £20 each plus then the piping to get both to the sump etc. He said the way he would suggest is just have the water run down the holes (with a mesh cover) which would mean that the water level would be around half an inch if not more below the level of the lid. I don't like how this would look. He suggested getting taps on the pipes near the sump which control the water level or something?
I have been advised by someone else that I could also do a small local weird, which would just be around the hole not the whole height of the tank, working the same as a standard full weir. He said this would let the level be higher as it runs over this into the holes.
My first question (I need to figure it out in parts as I am getting a headache from it all lol) is do I really need to run 2 outlets, I am thinking about where to position the inlet back in from the sump as won't it pretty much be going straight back out one of the holes? Also how will this effect the return pump? Does it all depend on how well the return pump is working, i.e if it pumps 2000lph this will mean 2000lph goes out of the holes (theoretically sounds right) just I have read about people getting the right balance, I just can't understand how there would be problems considering the rise of the water from the sump should make more flow out so a constant flow system.
Sorry for the ramblings and sorry if it doesn't make sense or it is stupid obvious problems!
Thanks
