Powerhead Size Help

[Granty]

Hey guys right now I have a 30g bow front tank and am currently using a koralia 1150gph powerhead and I'm wondering if it is too much for my tank as I grow leathers , Lps, and easy sps corals as well as quite afew anemones? If so what are your thaughts on using 2 240gph or 2 425gph koralia nano power heads as I'm looking for cheap but reliable name brand? Also I plan on upgrading to a 90g tank in a year or so, so the power heads would need use in the new tank when I upgrade. Any help or opinions would be appreciated. Pic is of current setup. Also rock flower nems keep moving as of this week after adjusting powerhead.

FWIW in my 30ish gallon frag tank I have a tunze 6095 (2500gph) in wave mode and a Korallia 3 (850gph) blowing across the tunze stream to add turbulence. So you don't have too much flow but it is always best to have flow (preferably variable or intermittent) coming from multiple sources/angles rather than one single continuous source.

BTW I am using a Koralia since I had it around...given a choice I never put 110volt pumps in my tanks anymore...they always eventually leak current and pulsing or controlling them kills their lifespan. Low voltage DC Tunze's or lower cost Jebao give you random flow patterns and strength and regarding the future upgrade you can go larger and turn them down to minimum to suit your current system.

What's your thoughts on the jebao rw-4 that can be found on eBay? Maybe 2 of them for my system?
