I have a 55. It now contains a 5" RD, which is why I am looking for 75 or 90. I'm in no hurry since it is 5", but if I see a good deal, I will snatch it up.
I would like to spend less than $300. Do you have any suggestions of an LFS that is a good place to find used tanks?
No the only LFS that I see selling many used tanks is Fish Den, but the price on the used tanks is not that good.
Here is an ad from craigslist it's a couple weeks old. She advertise the tank as a 125g but later changed description to a 75g. I called on it but no answer, hard to say if she still has it or not but may be worth a shot.
