Re: Tonys 'Peacocks Crypt' - 200L
relatively speaking (right word?) it compares to a 120cm tank with 2 x 54 then another 2 x 54 w for 2 hours...So similar to my set up.
I'm running just 2 x 54 at anyone time with the light 30cm away from the water and still getting good growth, so maybe kill the second 2 lights.
One thing I've noticed is, lowering the lights just 10cm induces pearling, and a lot of it, so this tells me the margins for error/algae are minute. I mean, who'd say 10cm was a big jump?...i wouldn't! but it's massive. I raised the lights to stop the pearling and give me 'breathing space' But with the same co2 injection rate as a high light tank...This is critical IMO
food for thought mate
Slick tank by the way 😀
