I have never smelled anything in the slurry albeit I have never run the AF4 more than 10 days without refilling. The unit will be put to the test soon during winter break where I will be gone for 18 days. I will have someone housesitting but I don’t trust them to feed so the AF4 will have to carry the day.Thank you for such a thorough detailed response. I think I’m going to mix higher salinity water specifically for the af4 and do the same as you. I smelled the food yesterday after 10 days on the second coldest setting and it definitely didn’t smell great. I have about 40 fish in my tank and some of them would be very difficult to replace. I definitely don’t want to feed them rotten food.
