I have recently stumbled upon an ADA AquaJournal article, and have found some statements that seem to contradict my EI views.
I wonder about the brown deposit though. Do they refer to the iron toxication (precipitation) caused by iron being released from the week chelates and reacting with PO4?
Excuse me? Nutrients cause algae? I thought we are well past that theory.Nitrogen and phosphorus are also nutrients required by algae, the archrival of an aquatic plant layout. The condition in which the body of water becomes enriched by dissolved nutrients is called eutrophication. When water becomes eutrophicated, algae tend to flourish.
Absolutely not. Frequent water changes are needed to get rid of Ammonia. Then of course they reset nutrient levels, but that's not the main point.Especially when an aquarium is just set up, the water becomes rich in nutrients and algae tend to proliferate, necessitating frequent water changes to remove them.
While I agree with the statement that algae growth is encouraged by nutrients, the ADA statement might mislead me into thinking that iron actually causes algae-bloom. It obviously does not. I have been having a stable 1.4 ppm Fe in my tanks for a long-long time with absolutely no thread algae growth, nor did I hear Tom Barr say that. In fact I heard him state the exact opposite: "No one has killed fish with Fe, nor does it cause algae."(...) excess iron in an aquarium encourages the growth of thread algae, turns water yellow, and the brown deposits of iron hydroxide form on the internal surfaces of the aquarium and on equipment.
