What do you put in your refugiums?
I know some people grow algae in their refugiums but should you also include live rock & sand? What type of lighting (ex. Metal halide or T5s) should you use for your refugium if you do want to cultivate algae?
Thanks for taking the time to answer my questions,
you should include LR but usually not live sand. it's an option. you may use metal halides for best results. a more affordable alternative would be t-5s
i feel the opposite. sand, 1 piece of LR ( if any at all, because they can act like bioballs and trap debris ) and i personally use chaeto algae. you dont need MH or T5s or even PCs over the fuge unless your going to double it as a frag tank. i personally use a clamp on work light with a full spectrum 6500K bulb.
Why no calurpa, I always see people selling bags of this stuff?
i have heard that if not kept trimmed it will go sexual taking over a tank and ive also heard that when it dies it releases the nutrients it took out, back into the water.
That and the calurpa can be evasive. there are chances that spores or pices of the algae can get into the display, and if you don't have a fish that'll eat it, it can take over your entire tank. california is going through this issue as it's taken over a lot of the cost.
how deep do you put the sand in your sumps???? I only have about 1 inch in my display tank.
