Brown Algae wheres it from

[scubasteve]

I recently did a water change and theres been an explosion in brown colored algae on the sand and glass. Its like a powdery brown algae, just enough to be annoying. Any suggestions as to what causes it or how to fix it? Thanks!

What is your water source? Brown algaes are primarily caused from silicates... A high quality PO4 granular sponge might help as they will usually remove both.

can you buy the phosphate sponge from the fish store ?

 

[steve-s]

Yup. It look like small bits of CC in a bottle.

I had this happen in my tank. Mine was caused by the spiking of NO3/NO3 durning the first cycle, and having the aquarium light on to long. Basically choke that stuff out by keeping your light on for only 8 hour periods.
