How do I harvest chaeto and how often do I do it?

[gordoncheers]

How do I harvest chaeto from my refugium and would it be ok to take the chaeto I harvested and give it a little shake in the DT so that whatever pods are on there can be shaken off or will that release bad stuff into the water.

How often is up to you.

If you are trying to be aggressive with nutrient export, then slightly more often (e.g. Q2-3 weeks) would be ideal because as the cheato grows, it can shade out the cheato behind it, so the growth of the ball starts to slow as it gets larger for a given size light/refugium volume.

If you're not so aggressive with nutrient export, then it's up to your tank. I usually harvested around once a month or whenever I remembered it.

When I had my cheato after some type of mechanical filtration or in a slow moving refugium where detritus would settle, I would always comb through to try and remove pods if I was throwing it away, but most of the time, I was usually giving it away to other reefers for free. If your cheato collects a lot of detritus, just be aware that shaking in the DT might cause a bit of a "snow storm". Unless you're trying to feed your fish, I would clean and put the pods after lights were out so they had a chance to hide in the rock work.
