Bet you can hardly wait. I am so glad i went for the upgrade, worth every penny. It's easier to maintain too once you have your settings how you want them. There's more access to be able to clean, and the auto top off means you don't have to fiddle with skimmer gates on a daily basis to keep the water levels correct.
As i did large water changes in the 130D, all i do now is change the same amount as i did before which is 2 cans of water, equating to 10%, so no difference for me there.
You will love it!
