Hey everyone I’m looking at getting a versa pump for my 15 gallon AIO. Will be dosing all for reef. After reading some posts and different things, I’m beginning to realize that it may be more involved than I originally thought. It’s sounding like the inner tubing has to be replace pretty often and it’s costing 20$ every time. Also, what does it come with in the box? What do I need to buy along with the pump? It doesn’t look like it comes with any tubing at all? Can anybody who uses this set up walk me through it. I’m planning to use it for a very basic application… thanks.
