Most common complaints

In owners' own words

“I disliked how close to the (clear glass) top of the tank it was.”
— @nyantoasty7579 on YouTube
“The mounting is why I bought a Chihiros and run it at 50% intensity.”
— @k9feces on YouTube
“Other irritation is that if light goes off in a power cut it doesn’t restart unless you ‘blue tooth ‘ it.”
— @ianhanley5626 on YouTube
“The lights are just too close to the water column and they do not cover the whole surface really well.”
— @prshuffle on YouTube
“My only disappointment is this one doesn't appear to have the storm settings and other fun stuff I've seen on other lights.”
— @someguy5673 on YouTube
“The par is abysmal.”
— pureProduct on Reddit
“Not only did it stall or crash during this procedure the light turned off and never came on again along with the touch pad being dark and no longer lit up! A bad firmware update was the result.”
— hennmann on FishLore
“I thought I could use the App anywhere to turn the light on after a blackout. I was 6 miles away and the phone failed to connect, even though I have a home network.”
— @mickcarson8504 on YouTube
“Honestly, I had a fluval 3.0 and I returned it. It just seemed like a lot of money to spend for a light that does what the other cheaper lights do.”
— mlash on FishLore
“I got my Fluval about 2 weeks ago and wish I had viewed your video before I plugged it in, now I have a serious algae & diatom bloom.”
— @gregorypeck2763 on YouTube
“This is great - but why did the update also cancel my current settings and require a password which I've never set???”
— Nick72 on FishLore
“If you have your ramp timer or should I say your built in timer in use and experience a planned power failure by your power company, a power failure etc. your lights WILL NOT come back on and in my case remained in perpetual moonlight mode PERIOD!”
