Been some time since an update,
As for the main tank structure itself... I did add a Neptune Apex, Trident, and a DOS. Additionally, I have one other DOS (unopened) I'm thinking about adding as well. My thoughts on the Apex? WAY BETTER THAT I EXPECTED! For someone who is into tech, details, and gadgets.. It's a dream. No to mention, it has eased the burden on testing so much. My tank has never been more stable. I've had it a month or more now and I love looking in to it at work and away from home. I also feel safer if I have the dreaded heater failure. Hoping it stays reliable.
I also, picked up a Hydra 26 that I plan on upgrading the pucks on. There's a guy online who sells improved pucks with way better PAR, power, and (less heat) capabilities. This will probably replace my HD16's.
Also, if anyone is looking for a container for the DOS, I'd skip the DDR and go with the Simplicity. Nice, clean, simple, has a better rep, and only $60.
