Help! Iron deficiency?
The substrate is gravel and Eco-complete. I've also got root tabs in the substrate. I use Flourish, KH2PO4, KNO3 3x's per week via EI Method.
The tank is 60 gallons. Two 96W CFLs in 6700K.
My test kits are old and I've either broken or lost tubes so I've ordered kits for testing nitrate and phosphate. I've also got Plantex CSM + Boron on the way thinking the iron would help.
I have hard water (I can't remember the specific number but it's fairly high).
It's an established tank but I recently went from low light to high light with pressurized CO2. I had a little green dust algae show up. I increased CO2 and the algae hasn't spread since. Still kind of playing with the drop indicator and what shade of green it's supposed to be. But keeping it a lighter green has helped and the fish aren't stressed.
New leaves on my anubias nana are coming in rather yellow. I don't have green veins on the new leaves, the whole leaf is yellow. New leaves on my amazon sword are more pale than I'd like as well. These plants were added a little over a week ago.
I was thinking this is an iron deficiency. The sword is still growing in so perhaps the roots haven't reached the eco complete or the root tabs. I don't remember if amazon swords take any nutrients from the water column?
So I'm looking at suggestions on how to correct this or perhaps I need to just wait for things to be get more established?
