210 gallon- rw8, 15, or 20

Martini5788 · 06/15/2015, 07:41 PM

Setting up a 6 ft 210 gallon. I plan on getting 2 of the jebao rw series power heads. I wanted to check before I ordered them, but I am thinking that the rw 15s would be the best option. Anyone have these and what size tank do you use them on? Thanks!

I just bought two RW-15 for my 120 tall.

4 rw-15 would work, with that length of tank ,I have 4 rw-8 in my 120.I have 0 dead spots.

I'm gonna have to start with 2 of them for financial reasons and then use my leftover koralias for the other 2.

Running 4 WP40s and 2 WP60s on a 470 (120x29x31").

One WP40 just went out and I ordered a RW20.

Will probably switch over to all RW20s

Just ordered 2 rw8 for my 75, maybe a little overkill but hey

I have two RW15s on my 150H (40L X 24W X 30H) I might need one RW8 to have 0 dead spots.

Do you guys think 2 rw 20s would work? I will probably do softies and a few lps but no sps.

kevin_e · 06/16/2015, 09:00 PM

I do

BigBlueTang · 06/17/2015, 12:43 AM

Maybe one more? I heard from a friend having them turned all the way up makes for quite a bit of noise, compared to their usual dead quietness.

If your rockwork is open you might be fine with 15s, but I'd rather get 20s and turn them down.

I have a 40B at home and everyone said a pair of RW4 s would be good. Shenanigans - my rockwork breaks up flow streams pretty good so the pair of 4s and a MaxiJet 950 still barely cut it. I scrapped them all for a pair of RW8s down at 50% and hid one of the 4s in a pocket in my rocks to get a dead spot. Now I have good flow that I am happy with, and the tank is responding accordingly.

I'm planning 4 RW20s for my 240, if that means anything.

How long is the 240?

I have 2 RW-15s on my 6' 180. They are more than enough. I like to run them unlinked with one on "W1" with the longest cycle and one on "c" on the shortest cycle. "C" on the shortest cycle is a little longer than "W1" on the longest.

Running them un-synced provides much more randomness (avoids dead spots). I also run power level 2 or 3 most of the time. More and my LPS get unhappy, especially my frogspawns.
