Hey guys. I was wondering if there is any benefit in getting a skimmer that is rated to handle a 125 gallon as apposed to a 75? I just dont want to end up upgrading if i dont need to. Thanks!:Cheers:
Yes there is. If the skimmer is bigger, it will handle more volume of water. I wouldn't get one that is rated for a 75...if you can, get the bigger one. You will be able to use it when you upgrade.
General rule of thumb is to get a skimmer that can handle about twice the volume of your tank. Of course this isn't practical for very large tanks, but for smaller tanks, the bigger the better.
