FAQ
I would like to perform a heating / cooling program where the temperature ramps from one set point to another over time. Are the PolyScience 20 Liter Stainless Steel Open Bath Systems capable of this?
That depends on the controller used. Only the Advanced Programmable controller can be programmed to perform ramps.
It is possible to have the circulation on without any temperature control being on?
No. If the circulation is on, then a temperature setting must be selected.

Great Looking Shelf
Color: Brown, Size: 4Tier48in, Color: Brown, Size: 4Tier48in
I love this shelf! It took two people to hang it and you definitely want to ensure you hit a stud on at least one side or 1-2 screws if mounting between studs. It is heavy but a single person can lift it, just not maneuver easily due to its dimensions. It has a ton of room and fits mini helmets nicely in my office. Where I mounted it made it difficult to an extent to install but if you are even somewhat handy, you’ll be fine. You absolutely need a stud finder to hang this shelf. Sorry, I’m married! I would buy this shelf, or versions of it, again. Very practical and useful to display autographs, housewares or decor.
Last note: do not over tighten the poles. The wood is soft and the poles are light weight. They are not traditional black pipe and weigh far less.

AWESOME Look and Quality
Color: Brown, Size: 2Tier60in
I love these shelves and have bought additional for other areas in the house. I love the look of the industrial pipes, the color of the shelves is perfect, they are sturdy and hold a lot of weight. They are somewhat difficult to assemble, but it's expected as hanging shelves are never fun to hang. I love them. If you are on the fence, just do it :)

Nice, but a bear to install
Color: Black, Size: 3Tier48in
Quality product that looks good on our shiplap wall of the wet bar space. The install was a real trip and extremely difficult. You definitely need 2 or more people to install as the direction tell you to put the entire item together, then hang on the wall. This makes it impossible to do yourself.
