The first 6 pictures are from before the water change. This is my 2nd week in a riw doing a 44 gallon water change ive been having algae in my tank so ive cut back on feeding and started doing more water changes. Also im ordering more snails, hermits for my clean up crew but still need to go through a 30 day qt period. Pictures 7-10 are all taken a couple hours after the water change and everything seems to be reacting well. The last two pictures are of my clown tang that i have had in qt for 15 days he is coming out of copper on Wednesday and will be doing a couple of water changes in the days after while I observe and decide whether to put him back in copper or to put him in prazzi.
