HI everyone. I have a 10 gallon tank that I just finished cycling with 5 very small silver dollars and a bullfrog tadpole. I have a 75 gallon with a beautiful handmade stand, that is currently housing my bearded dragon. I've decided to move my beardie to a smaller long 55 gallon, and convert my 75 gallon to a glorious community fish tank. I need advice about the safest way to clean it in preparation for my fish. Recommendations for adequate filtration and lighting. And, of course, stocking advice. I would like to use sand and various plants. And, hope to stock on lower, middle, and upper levels. The fish I really like so far are guppies, gouramis, pea puffers, panda loaches, wcmms, angels, and GBRs and BRs. Obviously, they won't all work together. I would love a few colorful and or entertaining showcase fish. I know I've dropped A LOT of questions. Being pretty new to this, and having so many needs and options with such a big tank, I'm pretty overwhelmed. I welcome advice from all. Thanks for your time.....
