Question ..

[vramirez209]

Okay so in march I started my tank woth dry rock. Now I noticed the rocks turning a dark brown. Its not diatoms cause the sandbeds pur white and I when I went to wipe to check of it was a late diatom bloom. Nothing happened. Now is thia normal or somthing I should be worried about. My po4 got a little high due to my r/o readingb2 tds . Im awaiting my replacement filters. If it is a phosphate issue what should I do to fix the problem. Of its natural then ill leave everything along.

Thanksb

Are you asking if a Diatom bloom is normal in a cycling tank??

. If it is a phosphate issue what should I do to fix the problem

Do a large water change and run GFO and CARBON.

Well I dont know what it is. It doesnt seem to be a diatom bloom. But I'm not sure its only on my rocks .

 

[vramirez209]

Could it be the rock curing ?

usually diatoms will be on the sand and glass as well but who knows. Doesn't sound like a phosphate issue to me. As was mentioned , do a water change and run some carbon -gfo. and see what happens. Couldn't hurt.......
