I have mine chained together I just use A LOT more tubing then I needed to I have about 8’ of line running from my main sump to my SH tank. Where I have a fan blowing over the line to help it cool off, a cheap temp controller that controlled the fan keeps it with in about 1° to 1.5°. Though this temp controller set up has only been running for about a week it seems to be doing ok so far.
