most cukes, are toxic, if they die, or get spooked,
i gotta ask are you obseessed, with getting rid of the algae??
if so, count to 10 and breathe deeply
although a PIA, your algae stages are part of your maturing process, tanks will go through soem, especailly when new, it is normal, but do not worry about removing it all in a day, by buying everything you can, maintain good h2o and keep after is, the PIA will become worth it again, b4 you know it
get your crabs and snails, and maybe stars, if you want, or conchs, you got an algae blenny, an dpersistence, that is the key ingredient, for the first 6 months you NEED persistence and patience, not every species in the ocean(don't take this the wrong way, either)
