DB junkie;3268151; said:10 by 4 by 30 are the exact dimensions of my Tenecor.
Anything taller than 30 is a PITA to clean/maintain. Even 36 is considerably tougher to work with then 30. I'm 6'2 and even 30 can be a pain at times (have to remember the 4 foot deep reach)
I'd use DIY filtration all the way..... But then again I don't have near the funds most people with tanks these size have.
IF it was me ordering one new I'd want at least (2) 3 inch drains. My tank now has 2 1.5s. WHO the hell would order such a tank with drains adequate for a 150 gallon I have no idea, but now I have to go in and enlarge the holes so I can run at least a bare minimum 5K GPH. IF new, I'd want a tank capable of flowing 12K GPH. Pumps seem to just start loosing efficiency once you pass a Dart, anything past a hammerhead (without spending stupid money) seems to get almost wastefull.
I'd run 2 hammerheads.
I'd have the overflow set up similar to the $1K 500 gallon for sale right now in Northern Wisconsin. Overflow on one end, returns on the other. My Tenecor 300 has trapezoidal overflows in the back walls... I hate it. Returns along the back wall. The friggin poo just rolls over and over and never seems to get into the overflows.
Plus a tank configured this way would be ideal for monster Characins as they seem to come from quick moving waters.
I was planning on 4 2'' holes. But i'm open to discussion, As i sad this is NOT my strong suit. I already ordered 2 Hammerhead's. And i'm going with a pond filter. Li advised me to.. Do you think 3'' holes are a must? Or the 4 2'' will be fine.. I will say the Bio load will be very heavy.
If it matter's this tank is for mostly GATF and Aro's.. As you know they grow rather large.
