Sump refugium

Is there any advantage to using more than one Macro algae... Currently using chaeto

I would think different types consume different nutrients, but I don't know for certain. Mr x or bribo would know more than likely

That was my thought too... But I know plants on land have chemical defenses that stop competition for resources

People mix macro algae in their refugiums all the time. It is something that can be done, but isn't necessary. The only advantage would be the same as having a large amount of 1 type of macro algae, being that more nutrients will be absorbed.

I mixed both grape caulerpa and chaeto in my refugium. There only seemed to be growth of a single macro at a time. In the beginning when I was having issues getting.nutrients under control the caulerpa grew line wildfire but after that the chaeto took over and the growth of caulerpa died off.

There really doesn't seem to be any special benefit to having both growing at the same time. In tanks with phosphate problems I would recommend grape caulerpa. Otherwise I'd suggest chaeto.

I have noted the exact same thing. My caulerpa's (grape & prolifera) thrive in a higher nutrient environment, but the chaeto doesn't do much.... Once the nutrient levels come down, the caulerpas slow down & the chaeto goes absolutely nuts. I like having some of each....

Time to get some grape. Thanks everyone.
