Chaeto in a filter

[Delphinus]

It should work. I grew chaeto in an Aquaclear for a while ... although I used 2x9PC's to light over the Aquaclear. If it gets light spilled out from the main tank you should manage..

what else does chaeto need? Is it used primarily for nutrient export? Any negatives to using chaeto? Thanks.

[Delphinus]

Just light and some current. I guess it's primarily for nutrient export. Some fish like to eat it but it's usually pretty hard to digest. I can't think of any negatives ... unlike caulerpa or halimeda it won't sporulate on you making a mess of your tank. Pods and worms and brittle stars like to hang out in it.

When you had it in your aqua clear filter did it ever float out of the filter or does it sink in water? If it does float what did you find was the best way to keep it in the filter?
Also do you know if its readily accessible in most LFS's? How do you tell if its healthy or not when buying it from the LFS?
Thanks.

It does float but if you get a large enough wad of it, it will just jam in. Sometimes a little string of it would fall out of the filter and then dangle in the current but I never really had a problem with it falling out. Worst case scenario you can take a small piece of live rock to hold it in place. Once it starts to grow it will just fill in and not move around so much.

Great thanks. So I just let it grow and when it starts growing out of the filter I just need to cut it correct?

[Delphinus]

Pretty much If it starts to take off you can find yourself pruning it every week or two.
