What an excellent video! Love that guy. Rotala kill tank.
It’s all consistent. You can actually a lot of the observations. My favourite is this photo:
This is exactly what we just said:
With the root tabs, it’s stunting. You can argue toxicity. Or you can simply say turn up the light keep your co2 because the guy is using loads of it.
High column dosing can pull that nutrition out but it needs a stronger driver it can only go as far as the light.
With low column and root tabs it’s taking its fill properly.
Low column and tabs is sexier because it’s not being force fed. I’ve already linked the N and P pathway at plant interface. And he refers to gavage feeding of foie gras. It has longer internodes because it needs more co2 to keep up and wants to get to the top. Fix the problem with more light and more co2. The left photo will look like the right.
Thanks for sharing that. Much appreciated.
Another piece is the CEC of the gravel - why we use root tabs instead of soil? Acidic soil, decaying humus, microbial assemblage - the partnership of biology - micro and macro - Bacter 100?
Use soil and root tabs. Real dirt. Go back to the old days. Your base layer needs to mimic kilometres of nutrients that the earth has. Fake it with clay and miracle gro/Osmocote or power sand. Then top it a bit more with dirt. Cap it with aquasoil or something inert. Literally mimics nature.
Load the traces, load the npk in the soil - replenish your + stuff daily because there are no remiwnralizkng rock we run to. And don’t bother dosing N and P — stock hard and feed your fish.
Dose the negative stuff N and P if you feel like it. Keep co2 in excess. Crank the lights.
Make it nature.
I’m off my soapbox! Lol
And I’m still going!!!
I’ve induced Mn deficiency with CSM and fixed it with CSM. The edta chelate accumulation does play into things but change your water and reset it because we don’t have billions of years of evolution in our substrate.
