Back wit da 20k

[Mr Cob]

So today I threw some 20k's on and my tank quickly captured my heart again

10k...14k...... no son para me!

I'm all 20k totalmente!

Especially in a tank that does not have actinic supplemental lighting.

Keep as backup bulbs. The old ones are technically only a few months old.

lol, yeah man. I missed the blue. They might be a little too blue....just a hair though. So, I'm going to shop around for some that have a more crisp/white blue if that exists. The 20k bulbs I have on now are Coralvue....just a hair too blue.

Im doing the opposite with my new tank. I hope I will like the reeflux 12ks. I will need the growth to get some of these frags into colonies though.

Yes, lots more growth with the 14k's I had on in comparrison to the 20k. But, the trade off isn't worth it for me. The colors really pop with the 20k. I did have some SPS perish under the 14k over time though. My bulbs sit like 4" from the surface and I had a couple of colonies die that were just a few inches below surface. I used a net/screen I made to prevent any shock when going from 20k to 14k.

I'm more into LPS right now anyways, so the less light is no big deal. I won't cry if my SPS slows in growth, I may cry if they die though. I have a few nice colonies that may not appreciate the change, but they sure do look pretty under 20k.

That was kind of my thought process. When I was in the process of going 14k...I put a couple of 10k's on temporarily and then the 14k's and I thought it would be good to do for 4 or 6 months just to get some of the frags out of the frag stage quicker, and then go back to 20k. It worked and now I'm happy with the 20k's back on.

I would try 12k or even 10k on a more permanent basis if I could get more actinic light in the half circle...but that's not an easy task. Limited room.

more actinic light= LED's less heat too, i kinda like the led tubes that the icecap fixtures come with, just like a t5 but led's inside

I know someone else that has vhos in their half circle.... lol but I think you will really like the 20k I know I do but like I said earlier I need a little spurt of growth.
