Hello, I'm in the planning stages of acquiring equipment and such, but one avenue I'm curious about recently is the use of macro algae in ceph aquaria, beyond their use in refugia. I am considering a 40 gallon breeder with a 20 gallon sump, but would like to maybe do a "planted" marine tank. (I know, algae are not true vascular plants), but I so rarely see anyone go for this and always opt for sessile inverts. Are there good non aesthetic reasons for that? I'm reading that certain algae can release harmful chemicals back into the water, so maybe that would be a concern? I'm reading through the forums for macroalgae right now, but would love to hear ideas if you've got them. Incidentally, I've been pretty successful at keeping FW plants over the years! Thanks, Ethan.
