What's the Best Contents for a Refugium?

[daniella3d]

I would go with micro algae instead of cheato as cheato I have read takes a lot of calcium from the water. I like the caulerpa prolifera the most as it grow incredibly fast and can be served to vegetarian fish as food. Especialy tangs like that stuff.

It will remove a lot more nitrates from the water because it is growing so much faster than cheato. A bit of cheato is ok for giving a refuge to pods but the micro-algae like the caulerpa is much more useful. I have also the caulerpa that looks like a feather and I can sell that stuff so quickly and make money with it as it too grow fast.

Thanks.
