Jebao RW8 for 90 gallon

falconut · 07/04/2015, 11:57 AM

My current 90 gallon mixed reef has had 4 Korolia Evolutions (2) 750s, a 1040 & a 1400 on a JBJ wavemaker for a few years now. Unfortunetly, I have had to replace several covers (supplied by Hydor) & impellers over this time.

I borrowed my buddies 6 monyh old Jebao WP60 to try. I like the W1/S3 mode, the corals all sway back & forth nicely. Something my Korolias just can't do. This pump is just really big.

Would a single RW8 be good to replace 2 of the Korolias & achieve the mild back & forth movement? I'd hate to buy it and find its to weak. The RW15 is close the double the price & bigger, so I'd rather not just get the bigger pump & run it lower unless I had to.

RW8 & RW15 owners please chime in. I need help deciding.

Anybody? Hasn't anybody tried an RW8 in a 90?

I use 2 rw-8 on a 55 gal, and they easily reach all the way across the tank at about 1/2 power. I'm in the process of upgrading to a 90 as well, and I am confident that they will be adequate.

Awesome, that's what I was hoping to hear.

I use 2 RW8's on my 90gal (one on each end). I have some of my LPS protected by rock structures to keep them from getting too much flow while the SPS can get all they want.

Primetime33 · 07/06/2015, 12:38 PM

2 RW8s will be plenty. I'm running them in my 80 gallon and I keep them running very low speeds.

I'm running two rw-8's on my 90 and they are too powerful in "else" mode (huge sandstorm). I have them set to the second lowest setting in w1 mode and running at different time intervals. Hope this helps....

falconut · 07/06/2015, 01:34 PM

Thanks everybody. Yes, this all helps. Sounds like they're the correct size for my tank.

I run 2x RW8 on my 48x24x24 120g. I can't run above 60% without clearing sand out of the corners.

will be fine on your 90g

I got my RW-8 today and was a little surprised. From the reviews I've read, I was expecting a more flow. I've set the flow on high and it has nice flow, but not as much as I was hoping. On full speed W1 it makes maybe a 1/8 - 1/4 wave. Guess I'll need to add a 2nd one in the future if I find I like it.

Size is nice, smaller than my Koralias.

I just ordered two RW-4s for my 55.

Please update how you like them when they arrive.

I haven't figured what setting I want to use yet. I was using W1 mode on the WP60, but the RW8 seems to hammer the closest corals with minimal reaction to the furthest ones in that mode. I have it in ELSE mode now, so we'll see how that works. I suppose (2) RW8s would give the best results.

I am looking into Rw-8 or Rw-15 and my question is why would you need two Rw-8? I have 90 g tank with 2 Koralia evolution 1400 and one side of the tank has a dead zone on the sand.

Bent · 12/20/2015, 01:31 PM

I now have two rw15s in my 55 and I still have dead spots. Wish I kept the 4s.
