Hi,
The plus unit goes to a 1" outlet, where the regular unit is only a 3" outlet. What size tank would this be going on?
THey do come with a mount kit for a eurobraced tank. The depth at which they set can set at a minimum of about 3" down, all the way to as long as you would want it to go if you decided to add a longer piece of pipe to it.
Thanks,
Jeremy
