So.. I've made the jump to the big tanks. A 65G was the biggest I could get in order to fit, unless I wanted to pay for a custom tank (no thanks). So I'm buying everything used for $140. Yes you read that correctly $140, no problems that I am aware of. Anything specific that I should be looking for when buying used? It can hold water and I'm not to worried as the seller seems to know what they were doing.
Anyways, second question. The 10G that I have at school with me, since I am leaving for a month (Christmas break) so should I take it home with me and use the 10G as a sump or is it worth bringing back? My friend is going to put my fish in his 55G while we set up the new one.
Final thing, I'm going with a freshwater planted. I've read that I can just use pool filter sand as its heavier than play sand and will work better. Not the biggest fan of gravel and paying 7 bucks for 5lbs of sand / gravel either, when I can get 60lbs for 15.
Thanks guys! Appreciate it.
TL;DR: Q1 - What to look for in used tank buying?
Q2: How to use a 10G as a sump.
Q3: Pool filter sand vs other.
