I currently have a 29 gallon tank. I just got a 100 gallon tank today.(freebie) What is the best way to convert it over?Will i have to cycle the tank over again? Also I want to use my filter and heater off my 29 gallon tank on the 100, and buy another filter and heater to make up the difference.. Will this work? I need advice on gravel to.... like best place to buy cheap gravel.Next the lid... The tank is made for two seperate lids. I would like to use wood. What would be the best way to light the tank? Can I use regular plywood? What kind of paint can you use that wont hurt the fish? Sorry so many questions, just excited about getting it going. Thanx for any help you all can give..
