I switched on my little 25 gallon cube. Had a sol super blue and it did okay, zoas grew, and stuff did stuff.

Changed over to a 4 bulb T5 setup and everything just exploded. Zoa colonies that were sprouting one polyp a month had 3 new buds in a week.

Now it could have been my ignorance about led's, not saying I had it tuned perfect or blah blah blah, but it's just easier. Lights come on, lights go off, constant light and spectrum all over the tank. No percentages or ramping. It almost took the fun out of it tinkering with the led's.
To add some pop and a little shimmer I still have some royal blues but glad I switched. Just easier.

oh geez, I just can't keep up with you guys!! Wait, I'm still on MH, so does that mean I'm caught up now ??

Not me.

I don't have an opinion but now I'm curious if I should have. Can ya go a little deeper on this one Denny? Interested to hear your take.

I run a Vertex Illumina SR260 48" over a 72" tank at the moment. I get great spread despite the size over the tank, very few dark spots, and the shimmer is perfect.

Though looking at my tank when it had T5's over it, to the eye - it definitely seems more pleasing. I've currently got them set to 25W/80B/80RB over 12 hours with a 2 hour ramp up/down.

The only down side to all of this, is I've had really painfully slow growth across the board. SPS? Forget about it.. and some corals completely hate it. I've had a wall hammer for 4 months that has yet to open. It's not dying, but it sure as hell isn't doing anything, despite it's placement. It still hasn't acclimated to the LED's it seems.

I think the way to go these days is an LED/T5 combo! Best of both worlds.

I had an evergrow led on my 40 gal but switched back to T5 and loved the depth of colors and brightness. I used only actinic blue and fiji pinks on my 4 bulb T5

i went from mh to led and couldn't be happier. Never used t5 but have seen friends add t5s to existing leds to fill gaps in spectrum with positive results.

I went from t5 five bulb to mh to LEDs . I was happy with the mh but I hated the issues with trying to keep the tank cool. I now run two Kessil a360w it's been three months and I couldn't be happier. My sps growth hasn't slowed I feel that it may have even increase . The versatility is amazing I love being able to change the look through out the day. The best part about the Kessil is no disco ball . I like the look of t5 but I like the look of a open top better and shimmer is a must for me .

I'm planning my MH upgrade already :)

I love mh they are sweet it was a hard change for me . I haven't sold the yet
