pump too big??

okay i have a stealth gro goin right now but have been majorly researching aero, hydro, bubble, ebb, and all the other mediumless growing methods im really interested in the bubblepoics method and thinkin of goin with bubble only cus i have three huge pumps that were used for a 150 gal salt water tank.

pics are below please tell me if im not suppose to use these and the demensions of the tubing are crazy wide? is that good or bad? ea one has in out?? labeled for the tubing? idk like i said im new to this and ive seen the normal pumps that have only one tube that pushes air.

well any info or help would be great!!! =) and i know of the whole bubblegang they are truly amazing but deff overwhelming lol no offense but you guys have so much, the info gets overwhelming!!! =)

ps im thinkin like one of the 40gal totes with round airstones and not the actual stones just the placements and the whole rockwool with pebbs and nets.

BLAAAAAAYZE.

i did some further research on it just now fluval 404 idk what the hell it is?? im thinking some kind of filter is so would i be able to rig it to do bubbles?? or can it already idk i hope someone looks at this anyways thanks ahead of time lol im confused high and tired night RIU!! =)

I dont know much about the pump, but I do highly suggest that you run that in sink/bathtub water for a few hours to get all the possible salt removed. They have a solution for that to remove unwanted salts, if i remember correctly its called "clearex" best of luck to you, If the pump fits underwater, and it doesnt make a tropical storm in there, I believe it will be fine.
