I often read that extra nutrients in the water will cause the formation of algae.
But is it correct to say that even if theres excess fertilisation/nutrients in the water, if the lighting period is kept shorter than required, it will not cause excessive growth of algae?
I have a lot of ferts in my tanks, but no algae that's any issues.
Very healthy plants and I am able to garden nicely.
Relative to algae, there are always excess nutrients in the water, the question is, what is your goal? To grow plants? Or to limit algae?
My guess is that your goal was to grow plants.
Algae popped up because you had too much light and not enough cO2 etc typically. Poor plant growth/health= algae.
Non cO2 tanks can have long photoperiods, excess nutrients and no algae.
Same for CO2 enriched tanks.
Low light, good CO2, good ferts, lots of algae eaters= best case for good plant growth with min input for most people's goals.
