As the basis of success, I always preach stability for a system. The less changes/swings that your livestock has to deal with, usually the better off you are.
On that note, I went ahead and changed out almost all of my major equipment. [emoji41]
I decided it was about time for me to try a DC return pump so I picked up a Jaebo DCS12000 and swapped out my current Sicce Syncra HF 12. They both roughly have the same GPH/hr rating so the swap was seamless. The nice part is the electrical savings and the ability to ramp the pump if needed. The negatives may be quality of the pump and longevity is going to be questionable on most DC pumps as well as we don't have a robust of a history with them. I've run this for almost a month now with no issues so far. I don't feel the need to have it controllable via my Apex as I have no need to ramp the speed up and down since I need the steady set flow as I use a manifold on my return pump and run multiple reactors off it.
I also had the opportunity this past weekend to swap out my Skimz SM201 skimmer for a much larger skimmer model. Sure, I pass up on a newer skimmer and one that has the space saving feature of the pump housed within the skimmer body but what I gain is sheer brute force and just about one of the most reliable skimmer pumps in a bubble blaster. I swapped a nice gentlemen in Temple for a Reef Octopus 5000 skimmer. When I installed it, I knew it was going to be tight... but I literally have a 1mm gap front to back and about 1.5" side to side. Wow! Like a glove?
This monster is rated up to 500 gals, but really 400 gals heavily stocked, which is still overkill for my tank at roughly 250 total water volume.
Lastly, I was running a no name CaRX, probably an old PM CaRX. It worked perfectly for me but I got tired of replacing the media so often and I wanted to run something externally instead of in the sump. Got an opportunity to pick up a MTC CaRX for a good price and I jumped on it.
Dual reactor setup, rated for 700 gals, built in pressure monitor, built-in needle valve, and the best part... built-in flow meter!
Once I'm happy with the transition to all the "new" equipment, be on the lookout for me to sell off the old equipment.
