AWC Daily amount?

[Randy Holmes-Farley Verified Community Expert]

Sorry if this is thread hijacking but how often should the sandbed be cleaned if you do AWC, or just gauge it by how dirty it looks?

Your preference. I almost never messed with my sand.

Good question. I'm still new to AWC, but I've been stirring mine periodically just before the daily water change.

I take a turkey baster and blow the very top layer and let my floss in the sump do the cleaning

How often do you two do this and do you think watchman gobies could do it for you?

Did you have any specific cleanup crew that did it for you?

Just curious, when using the dos for water changes and knowing all pumps have inherent metering error. How much error are you guys seeing a far as input volume over output volume? Do you see a gradual change in salinity?

For this reason, I would monitor salinity and make adjustments as needed. If the adjustment was substantial, I would intentionally adjust the in or out flows to be mismatched for a while to make the correction.
