Questions on ADA fertilisers
I have started using ADA Fertilisers for the last 4 weeks on my new carpet ‘Iwagumi’
style tank. The only plant I have is Hemianthus callitrichoides ‘cuba’ to carpet.
Here are my questions 🙂
1) ADA recommends using 2 ferts together for the first month of a new aquarium.
•ADA Brighty K (potassium)
•ADA green brightly mineral (trace elements and micro nutrients)
Correct me if I’m wrong but isn’t there other macro nutrients other than potassium that plants need, for example Nitrogen, phosphorus etc?
Also I understand that the bio-load from animals in the tank is converted to nitrates and other macro nutrients for the plants but I have a fairly low bioload with only 20 amanos in a 10G. And I’m concerned that the ADA ferts rely on the animals to produce the rest of the macros, and I have too low of a bioload to support all the carpeting plants?? (Also there is no other macro ferts from ADA just Brighy K)
2) ADA recommends using •Green brightly iron supplement for a matured aquarium from 2 months on. I am wondering if carpeting plants require the extra iron? I understand that stem plants like rotala rotundafolia require iron but is it necessary for carpeting plants?
3) I have a 10 gallon, about 40 liters and the ferts recommend 1 pump (1ml) per 20 L. So I should do 2 pumps. BUT I have a large amount of space taken by the large dragon stones and substrate which I calculated takes nearly half the volume leaving 20L would I dose for 20L (1 pump) for what volume of water is left or 40L (2 pumps) for what the volume of the tank is??
I am probably overthinking this since I don’t see people dosing ferts taking in account of the volume of water loss from hardscape.
4) Lastly, as my plant mass increase I would increase the intensity of the light, I have it at 3 levels from the 6 (half the brightness). As I increase the light intensity would I increase the dosing is the ferts and co2 too?
Thank you in advance for your time! 😛
