The KH is certainly not the culprit for the algae. Reduce your light
cycle
or start dosing CO2 and ferts, is this a planted tank?
I understand that KH is not the culprit for the algae. What I am trying to
do, is to get my water perameters right so that I can install my Christmas
present: a CO2 system :-) Yes, the tank is planted.
What is your current light cycle?
The current light cycle is 2 x 36w for 12 hours per day and a further 2 x
36w starting one hour after lights on and finsihing one hour before lights
out.
Size of tank and ammount of light?
Size: 400litre. However in terms of measuring the water capacity I deduct
20% for substrate and decoration etc. Therfore I calculate the capacity as
320litres.
Probalbly need to add ferts. What kind of algae?

BGA, BBA or what?
