Tank has brown spots inside

[astrocreep101]

I have had my ten gallon tank for about one month now and I am seeing brown spots appearing on the inside of the tank. I have done water changes usually four times a a week, and my ammonia levels have been going down lately. How ever I never bought a p.h. test until today, when I tested the water my p.h. was higher than 7.5. I als have a live plant inside could this contribute to my issue of spots and high p.h? Also will the p.h down help me resolve the issue?

Thanx for any advise
:duh:

its most likely algea

[plah831]

Yes, I agree. It's most likely the kind of algae called diatoms. They are a soft algae, and are very common in new tanks. They usually go away after the silica from the glass and new gravel dissipate (through water changes). Diatoms are very easy to remove, just wipe them with a paper towel or rag.

Just brush or wipe it off before performing the routine water change. :p:

I set my 10 gallon up in July, and about a month and a half later, I got the brown spots too. It then turned into green algea which choked out the brown algea. Now it's pretty much clear - and what does form comes off during routine water changes. You're on the right track.

Isn't that the sign that the tank is beginning to mature?

Thanks for the info, I was starting to become a little paranoid. :thm:

Yes I have had this on practically all of my new tanks it forms on some of the fake plants as well. It is a good sign although can be annoying.
