Did a little sump reorganization this weekend. I liked the ideas of having a "dry" area for the controller. While I couldn't quite pull that off with my limited space, I was able to at least move the controller to a spot above the sump where it would be less likely to get wet during normal maintenance. I ended up lowering the sump a fair amount, which made my return pump a wee bit undersized, so I upgraded that to a DC pump that's controllable.
I also put the sump and ATO reservoir on heavy duty sliders a few months ago, so I can get to them a little easier. That was really simple for the ATO, but the sump takes a little bit of creative plumbing and arrangement of cords and connections to make it able to be pulled out. The sliders are rated for about twice what my sump weighs, but I rarely pull them out all the way and even more rarely leave it out for more time than it takes to swap a filter sock out or clean the skimmer cup. It's really nice to have and I'm surprised I don't see more people with their sumps set up on sliders.
Finally, I added a KH Director. This kind of snowballed from my decision to upgrade my Kamoer dosing pump to something a little more reliable (I was unhappy that it just stops dosing after a power failure unless you reconnect with bluetooth). Since I was already on the GHL system, and everyone seems to love their dosing pumps, that seemed like an easy decision. Once I was decided on the dosing pump, it made sense to go ahead and get everything in a package together with the KH Director and "save" some money by spending even more...
I've started another post with my thoughts on the KH Director (so far) here. I need a little dosing tube management and still need to find somewhere to permanently keep the reagent and my alkalinity solution, but it's running and I'm pretty impressed so far.
