My first diatom bloom was 3 weeks ago. I’ve been doing a weekly water change (about 30% - scared to do more because I have neocaridina shrimp) scraping off the glass and scrubbing the rocks with a toothbrush.
By the end of the week it looks like the photos again BUT after the first week I feel like it’s gotten more of a greenish tinge to it rather than brown? Also the stuff growing on the plant leaves is more green as well.
I’m not sure if I’m still dealing with a diatom bloom or if there’s something I’m doing wrong regarding lights/nutrients etc.
Ammonia 0, nitrites 0, nitrates around 10 ppm. Dosing easy green at half dose 1x/week and just started dosing flourish excel. Also dosing flourish advance for potassium - was doing it 2x/wk but considering increasing it in case of potential potassium deficiency?
Any help greatly appreciated. Thanks!
