Congrats on your first spring.
Most important to is check all your plumbing for leaks. Once everything is turned on make sure everything seems okay, do not just turn it on and walk away.
I use a pond vacuum but like Sissy said a net works very good and I do 95% of my cleanings just with nets during the season. I only use the vacuum twice to three times a year, once in the spring, sometimes in the summer, but most important the fall cleaning. I use the vacuum to clean out filters on the waterfall and skimmer box (setup without bottom drains). I also have a skimmer so this assist greatly in stopping things before they go to the bottom of the pond. I use the Oase Pondvac and really like it. I found one on Craig's list very cheap. Be careful with vacuums, they are strong and can suck up the little creatures in the pond, my pond is usually very clear so I can see the bottom and I also go right into the pond even with the vacuum so my feet will move/scare most things out of the path of the vacuum (not saying I have not sucked anything up, I am sure I have) but try hard not too.
Net out all the big stuff first if you have a lot from the fall/winter. Check the debris for tadpoles, sometimes they can catch a ride.
I leave my water running during the pond vacuuming, it uses a lot of water. However I am on a well, if your not then use caution and use Dechlorinator
I clean or replace all my filter pads
I check all my electrical stuff too after winter. Lighting, cables, pumps etc
Do not rush to feed your fish, once my pond is running it is about 4 weeks before I feed depending on the season. I am Zone 6A also, but this depends more on water temp then time of year. (50-55 degrees)
Spring is a great time to get those plants in shape also depending on what you have.
Also check out all your fish and make sure they are healthy
Then sit back and enjoy the ponding season
