One large skimmer or 2 medium skimmers?
 

What would be more efficient? 2 skimmers rated at 150 gallons each or one large skimmer rates at 250-300 gallons.

Clean one skimmer cup, or two...hummm I would pick one. Just my 2 cents.

Lol cleaning a slimmer cup takes a couple min. No big deal for me. Also if 2 cups have to be cleaned less often than one then that's a plus

I say go big or go home. one large is my vote.

What if one large fails and you're on vacation? (this happen to me and I had cyano for a month an half)

Also you can't skim wet and dry at the same time

My skimmer has been running 24 hrs and it looks like an old hippys bong.....LOL
mine is good for 300-1000 gallons.... and I dont think it will even need replacing :)
the go big or go home theory has always been my motto

What skimmer is rated 300-1000 gallons? That's such a huge margin

Well since you are playing the what if senario, what if while on vacation your 2 inexpensive pumps die??? Rather spend the money of the better pump.

Sorry I never said inexpensive. My question is based on size. I don't plan on using 2 shitty skimmers

12" by 30" beckett air injected :)
Its good for more than that depending on livestock ect.... but 2 2000gph pumps get her fired up and if one goes it still skims till you see its less milky....
Im way more worried about a return failing while on vacay.... imo
