Problem:
a constant GW for years
What we know:
Volume: 10gall
Light: natural sunlight with 10 hours of 40W PC in reflector
Some more info required:
fish load and feeding, type of food and amount
plants load
no fish
100% planted
fertilization (yes/no, what exactly) all known variations
- CO2 (yes/no, ppm) yes, 20 ppm pressurized
water changes (%, how often) 100%, 50% or no WC made no difference
substrate inert old or inert new or with peat made no difference
About substrate. I have a feeling that this might be the most important thing in your case. What do you use? How often do you clean it if ever? How thick is the layer(s)? two inch total
Ammonia, nitrite, nitrate, phosphate level - would be nice to know too. ammonia and nitrite never seen in planted tank, NO3 from zero to 20 ppm, PO4 from zero to 1.5 ppm made no difference |
Too many combinations to list.
Access to sunlight is the most powerful aspect for plants and algae to react. The angle, duration and spectrum with temperature can trigger growth not expected to happen under artificial light fixtures. The GW is mostly visible at seasonal changes.
The answer to this experiment is the lighting period as per the
poll.
Thank you
