I need a check list of items i need to buy with a 55 galllon tank such as filters aerators stuff like that help is much appreciated
why gravel out of a tank that already has fish for the cycling to go quicker or something?if you're getting an Aquarium KIT then it will come with a filter, a heater, and a net.
in addition to that you're going to need a dechlorinator (most of us suggest Prime)
you're also going to need a Freshwater Master Test kit. (most of us suggest API brand)
and "Tropical fish food"
Then you'll need some source of ammonia to get your cycle started (either bottled pure ammonia with no additives, cocktail shrimp, or fish food)
a gravel vac is the same thing as a syphon, and there's one kind (called a Python) that you can hook up to your sink faucet and it makes cleaning/filling your tank REALLY easy.. definitely worth the $$.
you also need to see if you can get some gravel out of a tank that's already running and has fish in it (your pet store may let you have some of theirs, or maybe a friend that has fish?)
other than that, all you need is time!
