MY newly aquired pleco has done an amzing job at doing what I should be doing, cleaning. Of course now I am stuck in that he has done such a good job, there is seemingly nothing left for him to eat! I guess it looks like I will be stuck with the wafers or veggies solution. The "grow" bulb, which does a good job at producing algae, isnt working up to snuff, or the pleco's still doing an amazing job!
