Algae Issues On New Heavily Planted Tank

[ricardo48]

I have recently undergone an established tank bacterial bloom after adding laterite substrate to my existing tank and then heavily planting it with root tabs and liquid fertiliser.

I have 2x24 watt flora glo lighting on my 15 gallon tank.

I have

2 sparkling gourami
4 harlequin
5 cardinal tetra
3 platys - 1 is baby I raised in tank
5 octocinclus
5 algae shrimp
1 clown loach


The bloom cleared up and my water is fantastically clear, but I am now experiencing problems with dark green algae growing all other my plant leaves... I have trimmed back worse affected areas but its happening to the new leaves also but at this rate I will end up cutting all the leaves off!!

My worse affected plants are the brazilian pennywort and dracaena.

I have my lights on for 10 hours a day and inject Tetra Optimat co2 and diy yeast co2 from 2ltr bottle


My water test results were the following

PH = 7.5
GH = 18 dk
KH = 10 dk
CO2 = 9 ppm
Nitrite = 0.3mg/g
Ammonia = 0mg/l


Any ideas how to control the algae and so i dont have to keep doing heavy pruning?

Also any ideas why my co2 ppm reading wont go up. I diffuse the co2 using a powerhead through a micro bubbler airstone.
