Oh no, I'm not cycling atm, whatever is happening is happening solely based on what's in the tank.First, with RO you should see ammonia, nitrite and nitrate at zero. The increase in nitrite and nitrate is likely the "soil" aspect, this is not uncommon depending what is in these. I assume you are not trying to cycle this tank with artificial ammonia.
As for the algae, common green is to be expected but any type of what I refer to as "problem" algae is due to an imbalance in the light/nutrients. Provided the light is not too bright (intensity), duration can control its effct, along with floating plants. The majority of our aquarium fish do not appreeciate overhead light so keeping it dim is best. The other thing is the nutrients in the "soil" are difficult to assess. And, new tanks are naturally biologically unstable until the system becomes established.
oooh thank you <3 i can't wait till the diatoms fluff off so i can appreciate the pure green/red of these plants. XD I think, since its been sitting for so long, I gotta go refill my jugs of RO tomorrow but I think i'll do a big water change. P: They're rooted enough in there now I'm not worried about them floating/falling off stuff.Tank is looking great. I wish I had your sense of design.
