Lowering your tank temperature should *slow* the development of algae.

Are we talking about a bright green "light colored flimsy kind of algae
starting to develop on a piece of driftwood" which is directly exposed to
the lights? I'd be more inclined to wonder about 1) the length of time the
lights are turned on, and 2) whether you're overfertilizing.

I (only recently) achieved equilibrium in my CO2 injected 75 gallon with 190
watts turned on 11 hours a day and the temperature at 74º.

What's your fish load? You might want to test Ammonia/Nitrite/Nitrate and
increase water changes if your plants aren't using all your fish poop. If
you're dosing fertilizer daily, are we talking about trace elements only?
Test for Fe to see if you really need to be putting that much fertilizer in.

I should talk, but there you go.

Does any one know if water temperature is a factor in algae and plant
growth. Was wondering as I haven't had much algae in my tank until I
reduced the temperature by about 4 degrees, I've noticed a really
light colored flimsy kind of algae starting to develop on a piece of
driftwood. Any ideas.

75g
210w cf
pressured co2
heavily planted
plant growth is good
~7 cc of fertilzer daily
flourite/onyx substrate

thanks
