My stupid mom was left in care of my 10 gallon nano this weekend while I had to go away. I gave here specific instructions on what to do. I had checked everything right before I left so she wouldn't have to check the water quality. She gave a whole cube of krill shrimp every night for three nights in a row. There was so much algae when I got back and a whole bunch of decaying krill at the bottom of my tank. I did a 50% water change. My ammonia meter hasn't gone off yet fortunately and my nitrates and nitrites are fine. I siphoned off the crap from the bottom but there is still a whole bunch left that I couldn't get to. My tank still looks nasty. What kind of snail/shrimp should I get to clean this mess up. I'm planning on 3 margarita snails for the algae but what should I get for the uneaten decaying krill. I imagine my nitrates will dramatically rise soon once they start to decay a little more. Argh stupid moms well I can't really say that since its mother's day but still I'm pissed.
