Hi guys! It's been a while since I posted about this tank...I've been struggling with it.
In the last month and a half, I've gone through a diatom period, a BBA period, a SERIOUS cyanobacteria period (from accidentally leaving the lighting timer on "on"...), and now green water!!!
My tank is in my office, so I never noticed that the light was on 24/7 for a week...the cyanobacteria were out of control! After I correct the timer issue, I decided to add DIY CO2 and went away for a weekend. I came back to work on Monday and found a tank full of bright green water!!
I dose ~5-10ppm of nitrate and ~.5-1ppm of phosphate everyday, and I'd come back the next day with nitrate/phosphate readings at zero. I suppose my plants were using nutrients very quickly. I thought green water was caused by too much nitrate? Why would I have this outbreak given that my nitrate is constantly sitting at zero? Is it because of the unstable levels of nutrients? Should I just wait it out?
I've also read conflicting advices on water change or not. Should I do any WC?
I only have a few RCSs and pond snails in the tank.
Thank you for your input in advance. I will post a picture tomorrow.
