Questions on decreasing fuzz Algae on Glass
I have a 20 gal. High Lit tank (55 PC, 65 PC) 5hrs on
one and 5 on the other.... ( 10k and 88k bulbs)
Dose NPK, Plantex/Boron....
I use DIY CO2 (2 ltr. bottle) in a Powerhead...
I have a AquaClear hangon filter as well.
First question- Wonder if I should bag the Powerhead and
run the tube into just the AquaCLear???? Or is it more
effecient running this out of the powerhead??
I keep 10:1 on nitrates/Phos. and do 50% waterchanges
once per wk. always.. (also add K2SO4 at same time)
I was dosing Plantex @ 2mls. 3x per wk. (2 tbls. 591ml. bottle)
Now, I have not been able to get rid of this Fuzz like film
on the Glass and 24hrs after water change it's back..
I know this is due to a Fert imbalance.
Should I just back off of the Micros? Plus, I bet the DIY CO2 is not up to par.. (I do changeouts every couple wks)
Wonder if I should try Excel in conjunction???
Plants are Fine and growing fast with no major algae issues
Would really like to get some feedback on this please!!!

Get your CO2 leels up and make sure you have atleast 5ppm NO3 ALWAYS. It'll go away in a couple weeks if those parameters are met and you are diligant about thorough about cleaning the glass at the wc. Look for a post by me about this from 3-4 months ago, also another one by Laith.

Nitrates are always, 5-10 ppm on the average..

My PH has been rather low @ 6.3-6.5 ( was going to add
Baking Soda to help buffer)
kh and gh 3-5 respectfully
