Vermetid snails? On dry rock? In a week old aquarium? doubtful. More likely, the rocks that were allowed to dry for 2 weeks contain remnants of organisms that are now fueling the nitrogen cycle. And because of that, you’re seeing a bacterial bloom as bacteria tries to handle the decaying material.
op, your tank is new. You’re new. One of the biggest lessons you need to learn is that nothing good in this hobby happens quickly.
take a step back, don’t touch anything, and breathe. Your tank is going to look worse before it gets better. Much worse. That’s normal. Your tank is still sorting out the nitrogen cycle. And closely on its heels is the algae cycle.
It’s a result of organisms flourishing, exhausting whatever micronutrient are fueling them, then dying. Over time, this will stop happening. But for now, just stick to your maintenance plan and let it be. You’ll be rewarded for your patience.
