Nano Cleaning

[Sean]

Hey Everyone,

Got a quick question about cleaning the bottom of my tank. I got a 28g Nano cube the one with the 2 pumps and the HQI lighting. I had an extra power head in there but i just took it out, it did a good job of pushing the water around but my clown fish wasn't happy with the amount of current. Now i'm worried that the lower part of my tank is going to get dirty.

I'm really low on a cleanup crew.. think i'm down to just 3 snails and 1 really tiny blue crab. So 2 questions really. How do you guys clean the lower part of the tank without disturbing things constantly? and what type of cleanup crew should i get.. I'm thinking I want to stick with crabs over snails.. the snails just seem to be an eye soar and are clumbsy
