Brown Algae Bad or good

--------------------------------------------------------------------------------

Been getting a lot of Brown algae particulary on porcelain items and on glass in tank and the plastic plants i have

Any suggestions that i should od to remove this ??
Is this dangerous ??

My Temp is about 20-30 would this cause it ?

Sounds like diatoms to me. They are very common in new set-ups or in tanks with new substrate. They are mostly caused by silicates being leached into the water from the substrate. Once the silicates are gone, so to will be the diatoms

They are harmless. Just clean them off and do a few extra water changes. They typically go away on their own in a few months

I hope this is a typo - that your temp range isn't that extreme; do you mean 29-30 C?
