Hi,
I decided to redo my tank about 6 weeks ago from scratch, I replaced substrate and everything else. Fro the beginning, there was a small algae outbreak but I assumed it was related to the new pool sand. So, I let it go. But it has been about 6 weeks and it is getting worse day by day.
Plants had a period where no growth was evident, I had issues with my CO2 for ~2 weeks, but everything is back to normal. All plants are growing without exception (see pictures), but older leaves and tank walls are getting covered by a dense brown layer of what I assume is diatom algae.
Specs are:
270 gallons, 30in deep
Kh 4-6
Gh 6-8
6 39w t5-HO light bulbs, 4 6700k and 2 plant grow
Co2 concentration above 20ppm, I use a drop check (green). I know it is a waste but I run it 24/7
Substrate is bottom layer of laterite (flourite) and top layer of pool sand
I thought it was low CO2, but swords are sprunning new leaves every 3 or 4 days and stem plants are prune every week.
What can it be? Need more CO2 and is it too much light?
Any input is appreciated
