yep tds out is always 0. i sometimes wonder if my led lights are the problem? i did my own from rapid led and wonder if i have the wrong color spectrum. i have cool whites royal blue, and uv and green

What percentage is your Green of your total LED count, and what percentage are you driving it/them?

Same question with UV

[lordicon]

i have a total of 4 green and 4 uv and run them at 15%. and i run my whites for 8 hours and blues for ten. blues are around 80% and whites around 30%

Okay, well I don't think that's it. (those spectrums in really high intensity can fuel some algae growth, and red also (let's just say that I had some 'fun' with some LED's in the past, and my snails had some work to do))

I have used cool white + royal blue leds from RapidLED a year ago on a smaller nano without issue, so you are likely okay there, and I ran 5 whites and 7 blues at 100%.
