I've been checking out and talking to folks about wet/drys and alot tell me that its better and will work more efficiant if I had the tank drilled. I have no experience with drilling a tank and no way in hell would I even attempt to try on a 125 gal. But does it really matter alot if I just had a regular wet/dry w/o the holes in the bottom?? Im very determined to switch to wet/dry and want to do this right the first time and not regret passing up a better option later. Thanks you guys!!
