Getting ready to move soon and take down my tank,which will be a good time for me to set it up different.What would be better? 2 Koralia 3's or 2 Koralia 4's ? Is a normal 75gallon rectangle tank.thanks.I was thinking of drilling the back glass but on the tank it say's not to drill it.i was thinking of a closed loop but i do not want to take a chance.

I was thinking about that also,but not sure yet because im sure by end of this year ill be buying a bigger tank then thats more left over things i have again.
If you are unsure about the glass, DONT drill it. As far as flow, what I have seen work very well on 75G tanks with sumps/returns, is a Koralia #3 AND a #4 seem to work best on a standard 75G. I have tried 2 #3's and 2 #4s on one and neither seemed right, but 1 #3 and 1 #4 seemed to be perfect with a return/sump setup. If you don't have a sump/return then 2 #4's would probably be the correct answer. My tank is a 75G also, but a cube, so I have 2 #3's along with returns and closed loop on my tank.
Ok, for those who don't want to drill for a closed loop system, there was a thread on the forum thaqt showed how to make the intake tube but I can find it so if someone could point in the right direction, I would appreciate it. OR, will I really need one with using 4 Koralia 4's?
4 4's in a 90G? No, you won't need a closed loop with that.. I am betting you will have to even remove one of those 4's.
