I have had my tank for years. I had an algae bloom soon after changing the air pump. I have not been able to fix it no matter how many or how much of a water change I did. I am going to turn up and see if that fixes the problem.
Im going through this rn. I have been through many times with many tanks. My advice is to let it be. Do less, feed less, less light. Let nature do it's job.
The solution is NEVER TO USE GRAVEL...use sand - 2-4 inches of it...lessen your feeding...add live plants...period. TRUST ME if you don't, go and ask a biologist.
