New 14 biocube I'd help

[cole31818]

Just bought a used 14 biocube, put in Carib sea live sand and punched LR from LFS. They believe the rock came from a previous tank. Tank set up for 3 days with saltwater from
LFS, The top 2 rocks have a fine hair like growth on it. Here are a few pics in different stock lighting. Any thougts?

It is normal for rock in new tanks to develop different varieties of algae. This will go away as your tank cycles, and it ca take anywhere from a few weeks to a few months. Try cutting back on lighting if you want to slow its growth.

Thanks. I covered the tank and kept it dark for a few days and it seems to be dying off. Should I scrub it off at any point?

Yes you can scrub it if you want but it should go away in its own eventually

Personally, I would not go through the effort of scrubbing it off. Most likely it will come back. feeshna is correct...

Whether you are new or experienced in SW keeping, I encourage people to research everything. The “cycle” can confuse people so I recommend reading the best explanation of the cycle I’ve found by Eric Borneman. You can find it here - The Building of a Reef Tank
