A little 'bump' up the list for any more opinions...
Also, do I need to fertilize ?
My light is low (50W T8 + reflectors over 180 L) so 1.05WP(US)Gallon or 1.26WP(UK)Gallon. (I presume the basic WPG rule applies to US Gallons ?)
I have high Phosphates from the tap.
I inject CO2.
My plants are growing, but the hair/beard algae is growing better.
The fertilizer I have is JBL Liquid stuff with Potassium, Iron and Traces.
Would the ferts help the plants outcompete the algae at this low light level or make the problem worse ?
I have recently removed the fertilizer bags I was using and plant growth has slowed considerably, algae growth has slowed a bit.
I can't get the new lights for 8 weeks as the manufacturer didn't make enough !!
