Hey guys

This is growing all over the sand in my nano tank. There are no fish, only 2 pieces of live rock & an unknown number of baby CBS, which I accidentally kept alive...


The red-brown stuff is clumpy (holds together when you move it) and has loads of tiny air bubbles.

Here's a pic of one of the shrimp:


Anyone know how far along they might be?

Does your question refer to the the cyanobacteria or the amphipod?

Perhaps you would get a better answer if the request was clear.

It not cyanobacteria it's dinoflagellates.
Dose 3ml of 3% hydrogen peroxide per 10 gallons. Do this every 12 hours for at least 2 weeks even though it should go away after day 5-6.
