“I just bought a 3.0 for my tank. I see the 4.0’s are out now and I’m wondering if I should return it while I still can for a new one?”
Redditⓘ good to know
“It was sitting a little too close to the surface, and the light wasn’t making it to all the corners/back edge. This helps me get the light to all areas, and decreases the intensity to the plants with higher elevations on the hard scape.”
Redditⓘ good to know
“Could you please share your light settings? I just got the same light yesterday and I have a 40 gallon. Hoping to make my Rotala grow better and bring out plant colors. I run CO2 as well. The light seems so yellow compared to the hygger.”

“Well jeeze. Hoping I can return it to Petco without the packaging. I’ve had it for less than a month. Thanks for the recs.”

“Can you tell me what you're looking to accomplish? I have a 3.0 as well and I'm curious what raising it will do.”

“Nah, I'm just really bad at balancing my tannin content with my water quality. Finding it hard to hit the nice "black water" without too many decaying botanicals causing an ammonia spike. Just stuck in the gross in-between gamer pee stage EDIT: OMG WAIT!!! I totally forgot I DID tweak the settings!!!”
Redditⓘ good to know
“I also use lego as a riser for my FLuval lights. It's amazing that a 2x3 brick is the perfect size to fit in the ends of the built in width adjuster. I'm just looking for a slightly more optimal design, I like your use of the steps though I might need to see if I have any of those peices laying around.”
