First off, let me say I love this forum. I've learned a ton browsing various topics on here....

Ok, now my issue...I own a pond that is a little over 1 acre in size. The deepest part is about 15'. It's pretty much square except for 2 small areas that branch off. It's not fed by anything, but does have an overflow so the pond will never be over a certain depth. I'm not certain the exact age of the pond but I do know its over 15 yrs old. When we first moved into our house (5 yrs ago) the pond had a little algae, but was manageable. However, over the last 1.5 yrs water meal has joined the fight and is really bad. If the wind isn't blowing that stuff will cover the entire pond. I'm looking to add aeration in the hopes it'll help the problem. I'm going to attempt the 'RC51' system. I was thinking of having one hose feed four 9" diffusers in the center of the pond or split the diffusers up and have two separate units with two 9" diffusers each.

So, I'd be interested to hear the experts opinions on which set up would work best (1 diffuser unit vs. 2 smaller diffuser units). Thanks.
