Hello everyone,
First off I wanted to say that this site is very informational. I've been reading here for 2 weeks and learned a great deal. Thank you all very much.

My question is about pumping lines and more generally about water changes. I was planning on pumping water from my tank for water changes. But I also wanted to pump my RO/DI water into my tank. I thought about using the same pump but I don't know if I should. I was going to set up a closed loop system (I don't have a reef ready tank) with a scwd and an external pump. But I also plan to utilize this setup to take water out and in. I don't see any issues when taking the water out but when I'm bringing in the fresh water would it be a problem to use the same hose that I just discarded water with, and can I use this same external pump. If the point is the get rid of nitrate and other stuff, will it make a difference if I bring the fresh water through the cycle/discard lines. I ask because I remember seeing people with dedicated pumps from the ro/di storage. I should also note that I would like to take the water out and then immediately put the fresh water in for my water change.

Also, many people recommend the mag pumps, are they quite and can they be used externally? On Marine Depot's website they don't recommend them for external use. I was interested in the mag 12 or 18. Thanks.

Just an update,
I was looking at the Dolphin Pond DP-1200 pump. It has some great specs on paper (better than the rest) and cost $90. Has anyone had experience with these pumps? In the description on marine depot, they say they are very quiet, is this true? I'm little concerned about noise because my tank is in my living room in my apt. Thanks.
