The constant worry that looking at them the wrong way might kill them and all that money down the drain. One of the reasons I don't do saltwater.
I worried about that, as well. Spent a lot of money stocking up on every conceivable medication and a complete 55g quarantine/hospital tank, and here I am over a year later and I haven’t needed a single one of these items.
Buying quality fish, keeping the tank stable and clean, I think, are key. I don’t use RO (my tap is close to RO anyway), but I do age and preheat water for 2x 50% changes every week. The bare bottom is swept clean and the canister pre-filters are rinsed weekly.
Making the water change regime convenient is another key to success. If it’s hard to do it will be too easy to skimp.
Although I am not automated, my syphon lives in the tank, drain and water change hose is thru the floor right behind the tank. I simply turn valves on and off and the water change happens. I add ferts,
kH and
gH salts as I’m re-filling. Same with my ageing barrel in the basement. A hose with hot and cold water mixed is permanently hooked up to the barrel with a float valve, a heater, utility pump and airstones live in there, as well, all on one plug. The day after a tank cleaning, I just flip a valve to start the barrel fill, and turn on the heater/airstones to be ready for the next water change.
With low demand plants, it is a very easy tank, now that it is all set up and established.
So,
@Minninips, that is my reality (read my journal for more details), yours may differ but If the passion is there, a way can be found! (You
were looking for enablement, were you not? Lol!)
