No need to volunteer ...I've already done it. Problem is that you can't do enough of it. You can only inhibit it, sometimes temporarily eradicate it, but never eliminate it. It's always ready to take advantage of some weakness in the system. I have found some mercenaries that fight for the cause and they work cheap: Ramshorns - the biofilm thing. Removing PO4 works very well, but only in a non-planted tank. I've also set up cereal bowls with RODI water and added NO3 and PO4, plus other nutrients, set it in the sun for weeks and ...no algae. Repeated it, then, when no algae developed, added a little ammonia and POP: algae aplenty. Try it. It also showed me that algae spores are everywhere. WARNING: these are not scientific studies.
Interesting! An experiment I may try although I may have to use a strong grow light vs the sun as it is getting closer to winter in the Midwest :-)
Experiment aside, your comment does open a new avenue to explore for my situation that I had not considered...
In my 75g tank I have a lot of fish - lets say too many. This likely should lead to an increase in an increased amount of organic waste. The solids I think I have a good handle on. Ammonia waste... now this could be an issue.
I have a Fluval FX4 filter and the inner bottom tray is full of Eheim Substrat Pro. Between the hungry plants in the tank and the Substrat Pro I "should" have enough bio filter to handle plenty of fish.
The Substrat Pro is the same bio media that I have had for several years - I have never changed it out as recommended by the manufacturer.
Hmmm, could my lack of bio media maintenance lead to a "little
" increase in water column ammonia which in turn contributes to the excessive amount of algae in my tank?
And possibly why adjusting my macros, light level, co2, etc. only makes minimal differences in the level of algae?
