over the past few days some brown green stuff has shown up on my sand bed. Today I noticed some of it looked slimy and has bubbles. What is this stuff and how do I get rid of it?
Diatoms are just a natural things that happens in a new aquarium and will normally will subside with in a few weeks to a couple months.
ID: This Algae normally forms on the sand, glass and rock work of a new tank. It has a variety of colors from a dark reddish color to tan, brown and green. On a lot of occasions there will be oxygen bubble's trapped in the algae from photosynthesis.
HOW TO CONTROL IT:
Medium to strong flow across the sand bed and rock, and watch the amounts of Silicate being added to the system ( top off water and water change purity is the main cause for silicate being introduced to the system )
NATURAL HERBIVORES:
Astrea snail, Turbo snail, Tangs, Trochus snail, Almost all blennies.
This picture floats around as "dino's" sometimes.This is NOT a picture of dino's. This is a bad case of cyano. I know, because my tank was covered in this..covered. I removed phosphates and added better flow and it was gone in two days.
