Also if you live in the US, i keep seeing threads about Petco’s $1 a gallon sales with tanks up to 75G at times...
So if you save for a while you could own a brand new 75G for $75 bucks and slowly get the budget for everything else...
My local petco only sells stuff rated for 55 gallons and under, and the $1 per gallon sale is the reason the 10 would cost $42 and not more to set up, I found some good deals online, especially for the filter, $7!
