Enough Flow?

Try it and see. The Hydors will reduce some of the flow, though, so try to account for that. I would recommend trying a Tunze nanostream if it were me. You'd get the extra flow and less space occupied than comparable pumps.

Sounds like a good plan. Again, try it and see if it will be enough.

Didn't really help. Seems like you had it covered from the start. I'm just moral support

Wish there was a definite answer. You basically have several choices. You can spend the money on the maxijets and get a higher flow rate through your overflow/return or you can opt for a higher volume powerhead in the main system itself. Like I said earlier, a Tunze nanostream would be more than enough flow to cover the needs of that tank. It will give you more bang-for-your-buck and end up costing a bit more than the koralia and maxijet, but still provide much more water flow. It is also, IME, a better product than either the maxijet or the Koralia. Take a look at them and I don't believe you'll be disappointed. It will easily do the job of both pumps and then some at a seemingly intense 660 gph, but it is actually surprisingly gentle. It should also heat up the tank less than those two pumps combined at only 7w. That kind of flow rate, despite what you may think, is fine for that size tank. I think you'll be happy with it.

I got a laugh out of that line.. "IME..." hahaha.. this time your just being a little too cautious Amph.. I don't think it is just you, I am pretty sure it is a proven fact the Tunze is a much better product than the others listed. :thumbsup:

Mustang Boy, if you can save up for the Tunze, Amphiprion is 100% right and I would go with his advice if possible. It will save you time, money, and headaches in the long run and you will have better flow.

Just trying not to step on anyone's toes when it comes to product preference. I've had some issues with Tunze, though--just not as much as comparable products. Nothing's perfect and I just wanted to reflect that, too is all. I usually try to stay away from absolutes, too, since they usually come back to bite you, especially in this hobby.
