Shoelace we've got a high bar to maintain with this bad boy insta setup. Reaching 6 mos marker, 1 yr is so critical for showing possibilities with the method. You already know that 98% of people attempting this will just let the tank self-wreck with invasions typical for new tanks, or they'll put off water changes too long and send things sideways.
if you stay busy with preemptive, not reactive water changes and siphoning off all new growths so they dont compound, diatoms included, if you just feed that system and keep it sparkling clean by hand then as it matures and real coralline takes over, you work less.
From all the skip cycle tanks Ive seen, the ongoing error is the hands-off-till-doom approach where we can't get them to get in and get dirty no matter what; they'll accept any manner of compounding growth, horrible looking algae, all in the name of uglies and for that first 5 mos the tank looks horrible.
I see this routinely, on legit cycled systems that used bottle bac and testing and waited the 30 days.
your insta start was for nitrifiers, which are there for sure. how it looks in six months has absolutely nothing to do with your cycle, its how you care for post-cycled new tanks that determine if you can win buy-in from the skeptical masses here, and you should do that. I love seeing rules pressed, and won
That anemone wants your fish bioload waste as side-support, it wants meaty fare offered to it (find what it actually eats and repeat) and it wants clean water changes with no invasions to leak offending chems or irritants into the water. *Watch out for dinos, your tank is low on varying benthic pods and creatures so any mats that form (seeming diatoms) need to be removed heartily so they dont compound and support dinos which can wreck the system. I feel making predictions is critical, ahead of time,, vs just seeing what happens.
stores like Algen sell bagged pods, whats missing from your insta setup and what constitutes real live rock.
you can be experimenting with spot-feeding and very high quality reef feeds vs just some pellets. You can go beyond basic feed and see what happens into driving this reef and anemone to work and ensuring that happens by being busy for six months, not reactive. hope that helps. I want to see this work/usher in new options for the hobby and thats one tricky animal to try it with.
