I have 1 60 and 3 40s in a 300 with crushed coral all are set on else mode, I have no issues with my crushed coral , I guess if I had fine sand it may be an issue but if you don't I would be buying 60s
My tank is 72" long 36" Wide and 36" High. I am running a Jaubert Plenum on it that makes the sand approx 6" high. The sand is Caribsea SeaFlor speacial in the bottom and Caribsea Fiji Pink Live sand on top. The filji pink is .5-1.5mm in size. At one point the pump fell off on top of one of the rocks and pointed downwards towards the opposite corner, the whole corner was cleaned out of the sand within minutes.
If bare bottom go with the WP60!
I've been playing around with the settings and I installed the second WP60. The sand is now staying in place. I set both pumps to H3 pointing up and to each other from the corners. Out of all settings I like the Else the most but the humming noise is at lot less with the H3 setting.
just my 2 cents.
I bought a wp40 about 6 months ago, and liked it so much I decided to 'upgrade' to a wp60. In my 90g reef.
Yes, you read that correctly. Removed the 40, installed the 60. Best setting is W1, S2 - which is 75% of max. No issues with sand shifting, corals seem to love it, only issue is noise... not pump motor, that is dead quiet; the noise I hear is the water lapping up against the top frame and the overflow.
I tried W1, S1 - but it did literally send waves over the top of the tank!
As far as size difference, the 'ball' portion of both pumps is the same size, just the 'nozzle' part is larger on the wp60.
