i add cuttlefish bone to all my tanks aswell keeps snails shells perfect 
well the water round my way is very hard so therefore has lots of calcium in it but it may still need addressing. i am still very tempted to get more ottos as i only have one in that tank (moved from the 120l) and i know they are highly social fish so i should at least get 3 more. on his own he has eaten 20% of the algae in 3 days.i know you said you dont want snails but Nerite's are excellent algae eaters. ^^^^^^^^^^
Hey, Aaron, I am interested in Nerites, but I have soft/acidic water. can you keep them by adding supplements (calcium) that won't harden the water too much for my fish species? On that same token, can you do the same with amano and cherry shrimp?
