What we didn't mention in our opening post, and should have to give you the fuller picture is that we do do water changes and manual removal of existing algae- especially as it has been getting worse. We generally do 10% changes at a time. We have also tried the snails. The problem is that there is soooo much algae, they eat till they are full and haven't moved more than about 4 cm in a day... and then there is that worm- polychaete Oenone fulgida which we only discovered recently after we bought a clam and 2nd morning found it completely empty, covered in slime. We have bought numerous snails but they had always dissapeared myseriously- go behind the rocks and never return. So, even when we DO buy snails, they don't do much or get eaten by either the worm or the bloody mantis. (We originally had 2 mantis, but we caught one of them in January... the other one is much smarter and remains elusive) I'm not sure I want a sea hare, they get pretty huge, and I imagine they can disrupt the stone placement pretty easily. Good for a short term solution, but when the algae is all gone, then there is a huge slug...
