Hey I have a newly finished cycled tank and I did my big water change but there is still algae growing on everything!
When my cycle was completed the nitrates were only at 10-20 ppm
but it had already had its huge ammonia and nitrite spike so I did a 15 gallon water change on my 75 gallon tank and the nitrates dropped down to 5 but their is still algae growing!
The guy at my lfs
tested my phosphates 2 days ago and said they were very low and the 15 gallon water change would take care of it...I don't have a phosphate test kit so I cant test right now but what else could be causing more algae to grow??
