What size Jebao RW wave pump for a 75 gal?

I'm looking into getting 1 or 2 Jebao RW pumps for my 75 LPS/SPS reef tank. I have more LPS than SPS at the moment and my Koralia evolutions are just too much strong constant flow for the LPS and I can spend hours trying to adjust the 2 koralias to make all coals happy. The RW pumps come in sizes of 4, 8, 15 & 20. I can't find which pumps would be best for a 75.

Any of you have any of these Jebao RW pumps in your 75 gallon tank?

 

I use a wp25 on my 40b. It's about the right flow for the size though a bit one sided since I have only one. From what I've read, the wp25 equates to the rw8. I would think 2 of these would be enough. Of you went up to the 15 you would have more latitude on flow. And they can be dialed down to 10% and ramped up as needed.

 

I use a rw15 in my 50 gallon and its crazy overkill. I only have it at about 30% and it makes a ton of movement. The price difference between the two was like 5 bucks so i figured go big. You could do one rw15 and it would rock your tank.

 

Two rw-8 should be perfect

 

Thanks all. I think I'm going with the RW 8. I read last night of a guy who had just 1 RW 15 in his 90 gal and he was looking to trade for an RW 8. He said it was way too much flow on its lowest setting. So I think I'll start by buying 1 RW 8 and see how that is in my tank.
