I'm doing that right now, and I like how i can keep my sump running while doing so. Any thoughts/opinions in it? is it as effective as removing and then adding, or moreso?
Does anyone here add and remove water simultaneously?

There is no way that you can remove and replace as much water this way as you will always be taking out new water as well. Kinda defeats the purpose and wastes water. If you have a 100 gallon tank and you remove 50 gallons while filling at the same time, you may be doing as little as a 20-25% WC, as the rest of that 50% on the way out could be clean water that is just entering and then immediately exiting the tank. Also you run the risk of an overflow. No where near effective IMO.
Is your sump difficult to start up or something?

its not difficult at all. I just figured it would be easier on the fish to do it at the same time. Such as, have one hose emptying the tank while the other fills it.
It will help with acclimating them to a different temperature, but you won't have an efficient of a water change as before. You will have to change more water to get the same results.
When I do my WC, I pull out 5g worth and then replace with same amount. I don't turn off my sump. I figure the water I'm pulling out is at the bottom as I vacuum the gravel. I figure the new water stays near the top of the tank and then circulates throughout.
Works for me. Never have seen any adverse effects.

I guess there are no concerns about any chlorine killing BB doing this with the filter running?
Do you dose the whole tank while doing this with the sump running?
I tried this with my old 150 one time without my filters running. I think I ended up changing more water than I thought and severly stressed my fish. One even looked like it was on the verge of going tail over nose in the tank. That was the last time I tried that. Just stuck to the old method as that works for me.

thank you for the feedback. time to go back to the old method. I've only done this twice so far. My siphon drains 50 gallons in 15 minutes, and, with adjusting i made the water from the faucet match this. I added a capful of prime every 15 (before starting, after 15, after 15, after 15, after waterchange complete)
changed water this way for 1 hour.
