I just did a big change today, changed my substrate and added a ton of new plants to my tank. The thing is after, and I guess while, I put all the water in the tank there are tinny bubbles over everything. They came off the side walls easily, but I don't want to run my fingers all over every plant to get them off. Will these eventually go away? Are they bad?
This is common in a newly filled tank. When you add water all the agitation makes the water highly oxygenated, with more oxygen than it can normally hold. So once it settles the oxygen beings to return to a gas and escape. It's the exact same principle with a can/bottle of a carbonated beverage that fizzes up when you open it and let the CO2 out.
It's not harmful at all to the fish or plants and will clear on its own, but I would try to keep the heater clear of the air bubbles. Too many, and it could have the same affect as having the heater running in open air; really hot and cracking. A few isn't anything to worry about, just if it is covered in them.
