For the 60L Biorb, how many bags would be recommended?

I'd say 3 to 4 bags. 4 to be safe. Heads up. If Biorb is not cycling 100% well pebbles may get brown spots or algae. You can always clean them.

Are they big enough to be used in the bottom of a bathroom sink without washing down the drain?

Hello. It depends how big your sink drain is. Typically our biOrb Feng Shui pebble pack are big enough to not go down a bathroom drain. We hope this helps. Your biOrb Specialist, Natalie.

Are these special rocks for the biorb, or can I just use the river rocks I own?

Hello, these are just a decorative piece sold for your biOrb, you can use any decor you would like. We hope this helps!

Does the marble affect your tank’s pH?

The biOrb Feng Shui Pebble Pack will have no affect on the pH in your aquarium. We hope this helps! Best Regards, Your biOrb Aquatic Specialist, Jennifer.
