the tank is 36" the T5 light bar is 30" and it is 8-10" above the water so and I don't know what the actual par is. I want to rent a par meter from LFS to find out. I just started dosing .15 ml of vodka every night that started on Wednesday to get nitrate under control and doing a water change tonight. is calcium being that high an issue?
What type of light bulbs are in your T5 fixture?
