Hi John.

Great review on the Fluval Lights.

Gave the video a big thumbs up.

Bumpy says:

I own several 3.0 plants spectrum lights and I love them. Could be a few more options but the light spectrum modifying can really help control algae for example. They can run hot when on full blast but nothing major.

Johnny G Outdoors says:

Does it still simulate storms like the older version?

Prime Time Aquatics says:

Nice comparison!

Jay Wilson says:

Let’s do it intro a sweet mullet just slowly head banging to your music and than morph the mullet off to your head.

Brian's Fish Tanks says:

Looks like a great light!

Racing's Natural Aquariums says:

Light and tank look great! Thanks for the review.

Bryan Bennington says:

Where’d you get your fish artwork

Ben Coad says:

that is a cheap light lol usually 300-600 for a 3 footer heh

powerwh33ls says:

Does this light make the fish look any different than the plant 3.0?
I don’t have plants, but I thought maybe if I wanted them in the future I might go with the plant 3.0. However, if this makes my cichlids look better, than this is what I want.

Philthy Tanks says:

Looks like a great light, I’ve been contemplating getting into saltwater for a while now, just need the room for 1 more tank!

QueAquatics says:

Awesome review! Thank you

Gurvinder Parmar says:

I’ve always thought a marine light would look good on an African Cichlid tank.
