I have a ~35 gallon acrylic tank for $75. Don't know how cheap you are looking for. No chemicals used. It's actually a 24 that I added on a couple of compartments in the rear. One is the overflow and the other is a fuge. I can plug up the drain/return and you can use it as a stand alone like an Aqua Pod or use it as is with a sump. It dirty but easily cleaned. Here are some pix.
No worries man. Advanced? Wow, that's the first time I've heard about my tanks Actually, I have another one that I built and very similar in design that I'll turn into a QT.
