It's safe until it reaches 40ppm...but anything about 20 will probably cause a lot of algae problems.
I would keep doing as you're doing. It's open to debate, but I don't think you're adversely affecting the bacteria population with that cleaning method. Perhaps you should test it out, clean both sponges and measure ammonia a few hours later.
I'm betting everything will be just peachy, but be ready for a water change anyway.
People treat the nitrifying bacteria like a temperamental orchid...and really it's a weed. Bacteria wouldn't be everywhere if it were so delicate.
