Upgrating Cone Skimmer with CoralVue Bubble Blaster pump

[RuGlu6]

Thinking of modding my Skimmer that has 700 L of air/h pump with Bubble Blaster 3000 or BB HY-5000.
My Cone skimmer is 22.6" high, The pump is Hailea HX-6530 with 700 Lph air flow, 462 Gph water flow pump size is similar to BB HY-3000 5x6x7".
.
Bubble Blaster HY-3000 is 1100 Lph air, 400 Gph water 5"x5"x7"
Bubble Blaster HY-5000 is 2100 LPH air, 600(?) GPH water ??? size

Bubble Blaster "OEM" site.

The questions i have so far:

• how high the water level will be inside my skimmer if i go with HY-5000
• is BB HY-5000 is OK or too much in terms of WATER flow (not air)
• what is the physical size of the Bubble Blaster HY-5000 (cant find it on web, only BB HY-3000 size is posted as 5x5x7)

Appreciate any thoughts, suggestions and reasoning anyone might have
