Freshwater clams and algae effectiveness??

[Richer]

I have no experience using FW clams to clear waterborne algae... but there are other ways of doing it that is a heck of a lot cheaper than what your university is doing right now.

Cheapest way to clear waterborne algae (aka green water) is a complete blackout for 2-3 days. Increase the surface aggitation of the tank, do a water change, cover the tank with heavy blankets or black garbages... anything that will completely block ou the light. After 2-3 days, return everything back to normal, and do another water change. If things stay stable, the GW should not return.

Good luck!
