Hey rare changeup
that looks white light intensity caused more than anything you have a very clean sandbed cross section, as clean as our post ripped ones
Nice tanks! They have the expected growth due to missing grazers, nothing seemed wrong with either one.
i would remove rocks and clean externally yes, some peroxide in a spray bottle as misting, after total cleaning externally it’s not sprayed on the target, is ideal then rinse that off with saltwater and set rocks back. Detail siphon the rest of the mat up from the bed no rip clean needed since that rock scape is open easy access and low bioload tank, hand guide it
the siphoning to remove topical patches probably equates to ten or twenty gallons of new water made back up, that too is refreshing as a total move set for that specific tank
if you did that cleaning, then installed a cheap amazon pond sterilizer (they’re small) that cyano w probably not come back. If you want to clean first here, a few times it needed, that’s ideal and I think by dropping light intensity and upping blue vs white that combo alone will reduce your cleaning work. But a cheap pond sterilizer is likely to cheat the growback away anyway. Helpful on large tanks those sterilizers are. There are sterilizers for tanks like the turbo twist etc
but one that costs the same, and is rated for twenty five hundred gallons, is a better war tool and our trick is never installing them in the invaded condition. Only in the clean condition, to fight growback.
They don’t have to run forever, can be kept in a drawer until battle cheat time.
human hand from a resolved individual is what keeps the tank absolutely sharp clean, until maturation of the system let’s you back off. In 2025
for sure one day it comes, the cruise control earned. Much delayed. Mines been on cruise since 2009 no work at all other than when mushroom corals took over
we earn a true hands off nearly self running reef later, but not up front.
