The 150 would be the best IMO.
Yeah I know but it’s also like $100 more and I’m going to be moving them to the pond in a few months anyway. But if the other ones really won’t work I can try to get the bigger one. I might just get a smaller one for now and then buy the 300 gallon one in the spring for the actual pond? I gotta measure to see how big the pond I have is.
