I do all the usual stuff. I only use RO/DI water for W/C and top off. My top off is automated. I have decided I am not going to do the full zeo thing becuase I am too darn busy to remember everything. They do have some additives I really like though. One is sponge power and I had my doubts but it works for certain at increasing sponge growth and IMO its worth the cost since you use so little. I also like the coral vitalizer, and use their amino acids when I remember to do it. I am already back on prodibio and use their Bioptim and bio digest. I like the individual bottles of bacteria and food so they stay fresh and sterile untill use.
Anyhow I try to do a 30gal water change every 2 weeks, clean the protein skimmer every two days since it is filling now every two days. Change the carbon (I use Rox 0.8) every month. If I feel like P04 might be an issue which it never is anymore with the bacterial system from zeo or prodibio then I would use a GFO like phosban. I feed the fish heavy and think this is good for everything in the tank, as long as I export enough to make up for it. There really is no trick or one way to make a nice tank just stability and time. I really feel any method can work if you know it's weak points and always stick to the limitations of your method and setup.
I like the system I use, bacterial (prodibio), W/C with RO/DI, constantly run carbon in reactor, stable correct CA, ALk, and Mg by 3 part dosing the tank, lots of water movement which I still need more of. The only thing I am still not sure on in the new tank is the sandbed, I just loved the clean BB look and am thinking of taking out the SB, we will see. My skimmer is a real nice one but I think slightly undersized for the tank (Bubble King Mini 200 gen2) and I might want to switch to an external so I can use the sump as a frag tank instead.
