ahhhh, that's the same algae build up I have on the glass, substrate, etc. in my 5 gallon. Diatoms you say. My tank has the same Ammo/Nitri/Nitra readings as yours. As it is now, I'm vacuuming substrate ever other day as I see it growing on my substrate, glass cleaning maybe in 2-3 weeks time as it starts to look like yours but I won't wait that long to get to your look, lol. I've tried Phosguard, light siesta 3 on 4 off 3 on to no avail with my weak oem light(3leds). I've tried Excel with no results but have since stopped. I've also tried Tetra Algae Control but it only affected my swordtail hanging at the surface gasping for air. LOL. My tank been setup for approx. 8 months now. I do feel the more nutrients I apply the faster this algae comes back.
I just acquired a better light source so ... and a new plant so... . Will I ever find that balance? According to API phosphate test it's nearly zero and thinking it's silicates in water source but I have no tester to test that.
hmmm, they say diatoms will go away on it's own, now, would it be wiser to just let the diatoms be to see if it consumes it's food source and starves itself to extinction? To do that would be not to clean and no water changes as long as Ammo, Nitra and Nitri are at tolerant levels for my fishes? or using ro water? if there's no phosphate or silicate can the diatoms live off some other nutrient in the tank? But then again isn't that what Phosguard fer? to clean out the diatoms food source, silicate/phosphate?
I have no ro water, maybe could try doubling up the dosage of Phosguard to see what happens.
