Gastropod Shortage

Now that the system is full of happy fish who reqire a ton of feeding and coral that requires a ton of light, we're getting algae blooms.  This wasn't unexpected.  I just need to add a ton of snails.  I'll be adding a combination of Turbo, Trochus and Cerith snails.  I really like the Trochus because they can right themselves, but they are going for around $3 each these days.  That's three times the price of a turbo and six times the price of cerith snails.  I'll not be getting as many Trochus as the others.  Turbo snails are the all-around winners when it comes to cleaning capability.  I've never had cerith snails before, but everything I read seems to say pretty good things.  We'll see how it goes.
