Hi dantrasy! With your tips awhile ago, my baby tears been growing very healthy. I bought a canister filter and just received my glass pipes and inline co2 diffuser. I just decreased my lighting from 8 hours to 6 hours. I'm fighting hair algea atm and they keep growing and growing and I can't seem to get rid of them. I vac my gravel, do 2-3 water changes every week, cut down my dry ferts dosing, and now I just cut the time of my light. Any suggestions?
What is your photoperiod and CO2 cycle? A lot of times in high light + CO2 tanks, the owners aren't managing their CO2 well.
Also, I concur that reducing ferts isn't the best strategy. I will say, however, that it sometimes
works (through an indirect fashion).
The *best* way to figure out how to control the hair algae is to understand what parameter is out of balance (e.g. too much light, too much fert, not enough CO2, not enough flow, etc.). Unfortunately, I think that process is mostly trial and error =(
I usually only run into hair algae problems when my CO2 is too low, my CO2 is not in sync with my lights (should turn on before or at same time as lights and turn off when lights turn off), my flow is too low (like waterlogged areas of overgrowth), or my tank is filthy (overfeeding, not cleaning away plant detritis, etc.). Do any of these seem possible or likely to you?
Also, how often are you fertilizing? and with what?
