These are some thing's that I have that are taking up space under my 90g and at my in-laws.
Prices are not firm, I'm open to trades.

This is black sand, same stuff that is in my 90 g and my salt tank. It came out of my lizard tank when I took it down. I there is a bit of this stuff. So lets say 10$.

This was in my lizard tank a long time ago Its all in a 5g bucket right now.
$15

A 5.5g with a glass lid. $15
This is what I used to have in my 90 and there is allot of it. I'm thinking 40$
And there is enough to fill a 90g about 4-5 inches.
A 15g tank with lid and a plant grow light. Light grew the plants in the tank like crazy. $50

This is a sump that I have at my in-laws that I was going to use in on my 90 gallon, but I don't have the room right now. It is 18wide X 36long X 19high. which makes it a 53g and it is heavy. I think its made out of 1/2 inch glass. It is drilled on one side. $75 SOLD
That's it for now till I check and see what else I have. All the gravel is nice and dry and has been cleaned. Remember I will take trades and offers.
Thanks for looking.
