hi bro, really busy past couple of weeks.
anyway, thanks for the advise.
yes that was after target feeding ... started to throw up a lot. one thing i noticed later is brown powdery algae started to accumulate on my walls. also saw my BTang starting to have ich.
checked params, nitrates at 25ppm, rest are nil.
started removing them off the walls, and for now did about 25% WC with remaining NSW. also put in biohome plus.
so far yuma seems slowly recovering (now that they're not fully open, good time to frag ? )
BT still lively and eating a lot, though ich became quite bad with dots covering most parts. As of last night, observed that dots almost gone
all the rest of inhabitants seems ok. still continue to monitor first.
