if it goes several more days and u get tired of seeing it, do a takedown cleaning where the tank is simply disassembled and sand taken out and rinsed like we do. All new water
Set it all back up with no snails, perfect clean bed
HA’s suspect mechanism for the cloud is snails so when it’s time to force act, start with whole tank vs 90%
that patterning comes from the sand rinse thread we have zero instances of persistent cloudy water after a rip clean. 90% wc leaves snails, and it left sand so those are the two zones when you need to step it up, perhaps it will resolve before then but we’re closing in on over a week already
it might be unideal and a lot of work, save it for last place then. Stumped too, but there are basic patterns to fall back on as well. Disassembly cleaning, 100% animals taken out and tank cleaned, has no cloudy water rebounds in 30 pages of the thread. *CWentz from the SR thread is posting some rework challenges with a type of persistent dinos or diatoms, but that’s a benthic growth on the sand we see and his water is clear. *suspended* growths are unique in that something has to keep pumping them up somehow so in the end we can guess which topical cause might be at play but cleaning from the bottom up is different that cleaning from top down and only as a partial move. Save the big three hour job until you can’t stand it lol
it will never harm a nano to disassembly clean it, and it won’t cause dinos. It is just a good work session as the tradeoff...annoying, but we r running out of alternates to try too
