After many months spent on the italian forums, i am finally here, since i think there is no better forum on the internet regarding planted tanks.
I would like to apologise in advance if my English isn't the best but as you already recognised , it is not my main language.
I am having a huge problems with BBA, they are attacking all the plants in my tank, which is a 100 litres, 80x30x40 cm
My values are:
Ph:6.8
Kh:5
Gh:8
No2:0.02
No3:8
Phos: 0,05 (they were higher than 5 mg/l when BBA exploded, I slowly reduced them with rowa phos resin which is still in my filter)
Iron:0,1
Co2: 30ppm
My lights are 4 t5HO , each of them being 24 watt, they were on for 9 hours, now 8 hours
2 are 6500k
1 is 4000k
1 is dennerle specialplant (2700k I think)
I change water every 2 weeks around 20 litres with salts from seachem to reinstablish natural values of the tank. (Seachem equilibrium and seachem alkaline buffer)
My EI dosing is this one
As you can see I dose on Monday's, Wednesday's,Friday's and Sunday's .
I tried to burn algae with seachem excel but no real result.
I tried to install a powerhead(nanokoralia 900lt/h ) for higher flow.
My co2 is on point: 1 hour before lights turn on, turns off 2 hours after lights go off. Drop checker is a vivid green.
I tried to dose prodibio bio digest to increase good bacters in my external filter, hydor prime 20.
Now I think the problem here is the light , I think it is either too powerful or too close to the surface of tank (it is at 7 cm now)
I don't know if I am right , anyway I might turn 2 lights OFF and leave only 2 tubes (6500 k 24 watt each) ON , so I can reduce more than enough my lights power. From 96 watt to 48 watt.
What can i do ? I am fed up of spending so muchhhh money to limit this problem, it is annoying and i am losing faith, please help me and sorry again for my English and the length of my post.
