okay, i've tried to read through and i just had one new thought to add to the table.
i recently came across a post by tom barr suggesting the relationship between algae growth and water changes. water changes supply CO2 rich water. As we know from the many, many threads on this forum, algae usually comes from lack of CO2 or too much light (maybe this is just my opinion here but this is what I've gathered from posts by Byron and several of Tom B's posts elsewhere).
i hadn't thought of water changes supplying co2 before.
Well, i threw my back out last week and couldn't do my regular weekly wc on wednesday. this is after i had seemingly struck the perfect balance between frequency/quantity of water changes, frequency/quantity of ferts, and frequency/quantity of excel. well, three days after missing the water change, lo and behold there was a brand new type of algae in my ten gallon (which has too much light but algae has been in check nonetheless)...green fuzz algae!
i immediately drew the conclusion that because the plants were missing that fresh co2 rich water from the missed water change, that algae the opportunist came along and used the nutrients and light.
does that make sense? it does in my brain but i'm having a hard time typing because my hands are freezing cold.
