Hey Jeremy this is Shane Wise. I need some advice. I am planning a new 125 in the next month or so. Thinking of drilling two over flows in the back glass top corners, hard plumbed to maybe a 30gallon sump 10 gallon fuge. Wanting to split the return to both ends of the tank for maximum flow. Wanting to later add a tunze on each end, but for now the return will be the flow in the tank. I have had allot of luck with the mag 950 in my 55, it has been running for over five years and puts out decent flow. Was wondering about the mag 24 or 36. The 950 has been dependable and runs pretty quiet in the sump would either of these pumps be a good choice for this set up, or do you recomend another pump in this price range for the set up. Also what size bulk heads would I need to use? There will probably be three 90's in the line before it hits the sump. The 55 has a titamium heater and has also never had a problem which one and what size do you recomend for this tank? Your advice has been helpful in the past and I am trying to take my time and plann this tank completely out before I get started on it. Thanks!
