Hey guys, I am looking for some advice in building my first plywood aquarium. The internal dimensions are planned to be about 20"wide, 24"high and 43" long, totaling about 90 gallons. However, I wold like some outside input for my plan, and some stocking suggestions when I do get to that point. My goal will be to build the tank at least this summer, then start aquascaping and hopefully have it done sometime close to Christmas, it should be a slow process to save up for. I am thinking about a $550 budget max, but less is better. So far I've estimated $50 in wood and lumber, $80 in the sealant (I'm thinking Pond Armor), and about 70 for the glass/ viewing pane. Then about 120 in filters, with three Aquaclear 70s, but the third installed later in the process. As for heating, I am planing a tropical, so a 300 watt sounds about right, my room is already about 71-72ish. Sand is my preferred substrate, so about $50 dollars in that, and I want to plant it, so I'll leave a $40 budget for some plants (But easy plants), which adds up to $460 if I did my math right, although I may not have, which leaves me with about $90 left in the budget plans. Any other important equipment I should be remembering? I plan to have it as low tech as possible, and to try to cut down on prices a lot by buying used. However this is for all new stuff. Anyone notice any immediate problems? Anything I should have included, or prices that seem very off? Thank you for any advice, and also feel free to start throwing ideas out there for stocking. I am open to all suggestions, but I am thinking a tropical peaceful community, with a few schools and a few large centerpiece fish.
