lighting

Hello my tank is about 1.5 yrs old, im having a green hair algae problem but its only growing on one piece of my rockscape, im aware there are fish and inverts that will help remove it and general maintenance will help as well but im looking for help on understanding why this is occurring? Its a...

Just that question: Do you cycle your tank with the light on? My intuition is that the tank needs to exist as if there were fish in it, for it to cycle in a way that will be a "true" cycle, but I'm finding confusing information.

Hello everyone! Already in my last thread with my montis i mentioned of thinking about upgrading my lights. Now after my holidays, during which our fuse tripped twice at home, after coming back i noticed one of my hydras went out, it seems to be the power supply that failed. I will go to my...

Hi! Hoping to get some opinions on other lighting options for a 15-gallon column tank. Currently running two blades, grow and glow, but I'm having issues with the entire grow blade getting extremely hot, including the plug. I did reach out to AI, so I'm hoping to find a solution, but in the...

Hi everybody. I have a bunch of unused aquarium equipment that I need to move. My wife wants the guest bedroom back so it has to be moved out. This is all stuff that I bought for my latest build but I have decided not to use. I have a tendency to overbuy equipment with the thinking that I can...

So I recently moved all my corals into my larger system finally, and turned my nano reef into a macroalgae tank that I’ll be putting dwarf seahorses in. I finished all the macro scaping last week and this was the final product which I’m really satisfied with Pretty quickly the macros began...

Let’s see your lighting after sundown! For those using the AI Prime 16HD, what settings do you run? I have mine mounted about 8.5 inches off the water, with roughly 3% from violet to blue and 5% on moonlight—otherwise, I can’t see much. I also have my lighting set to follow the lunar phase...

Whatsup fellas, I went back and forth a lot but I decided on going with a 230 system, 190gal display 72x26x24. I’m pretty sure I’m gonna do gyres icecap 4k’s maybe one on each side with 2 nero3’s one on each side of the internal overflow to blow behind the rocks. I am stuck on the lighting...

I know there are many discussions about needing uv lights in the 385nm range. And manufacturers dont put many UV bulbs in the lights because they are expensive, or so I read. I saw these on Amazon and said for the price, what the heck! Any!! Input on the fact that I mihht burn my corals or are...

Hey! I’m going to get a 60x24x24 150gal tank. I’m very fond of the nicrew hyper reef gen 2. How many and what strength do you think I need to cover that tank? For mixed reef And if you think there are better options out there I’m open to anything

Good morning! I'm new to reefing and I've got a few questions. I've built a 40 gal breeder tank, fully cycled it and I've currently got a fish fish, but wanting to start adding more corals, right now I only have one Zoa frag. What's everyone's favorite light for best growth. I've currently...

Somewhat new to reef tanks. I’ve had FOWLR tanks before but I’ve never had any coral so with that being said, can I get some help with finding a light? It’s a 75gal tank. Plan on starting with softies and leathers, but later on down the road I would like to keep lps and sps. to be quite honest...

I got a second reef breeders photon last year for my 150 and it’s a bit overkill now since I have restarted the tank and don’t have colonies anymore so I’m looking to sell it. I am located in the Northern Cambria area 15714.

As the title says, I’m looking for a AI light that will sufficiently grow macro algae but I don’t want just the refugium ones since it is a display tank. My current light is a freshwater planted tank light that seems to work pretty well. However I would like to switch to as much AI equipment as...
