Except if he ever goes on a 7 day vacation upon his return things will be ugly, very ugly
Just a silly statement. I go on vacation and leave my EI tank with no maintenance for 7 to 10 days regularly. Sometimes when I get back a little algae has developed. I get back into my normal routine and the algae regresses. No big deal. I've never come home to a disaster.
Niko has a fine point in this discussion about one planted aquarium strategy, but attacking other strategies and making over generalized statements only hurts his argument.
The fact is there are several planted aquarium strategies that work well. And each aquarium is unique. For example I have 2 adjacent 30 gallon NPT's in my fishroom. They were set up to breed apistos. They have the exact same light, same filter, same substrate, same water chemistry, they were started on the same day (over a year ago), I never add ferts to either one, and both house apistos only (a pair in one and a trio in the other). One tank has excellent plant growth with very little algae. The other is covered with cyanobacter.
