I second this. The best thing I ever did was switch to eco earth. No smell, perfect humidity, and it looks nice. I spot clean and then do a 100% change once a month. I don't buy it in the bricks though....I buy the uncompressed bag. Its like $8 instead of $4...but I only use 1 bag per month, so its not so bad. I find the bricks to be a pain in the rear to prepare.
