Review: Caused MASSIVE algae outbreak due to brightness. Upgraded version is great! - UPDATE #2 I upgraded my original review from 2-5 stars The customer service has been excellent from this seller. After I got my massive algae outbreak under control(see below) I purchased the upgraded version of this light which now has the ability to change brightness and color in 24/7 mode. The only way to tell if you receive the upgraded version ( because the old and new are currently mixed together at the warehouse) is to look at page 10 of the manual. If the top line on the page says time, color, brightness, you received the newer version. There is a battery backup in the control that saves current settings in case of a power outage which is a great feature. There are helpful programming videos explaining how to set up the controls, so it's not as complicated as it initially seemed. I am currently running 2 different sizes of this light on 2 separate tanks and have been very pleased with the newer version. My plants are doing great and there's no algae outbreak in sight. I will buy more in the future. ORIGINAL REVIEW. The controls are quite complicated to program on this very bright light. The biggest problem that I have experienced is that there is no way to dim the light intensity level when on 24/7 mode, which resulted in a MASSIVE hair algae outbreak that covered all of my plants, glass and rocks in a surprisingly short period of time. I have pulled out an entire tank full of live plants 3 times and dipped them in diluted peroxide followed by dosing of liquid carbon to try to keep them from dying due to algae suffocation. I have also removed all of the hardscape and scrubbed it down to remove the blanket of algae covering it as well. I have been doing 50% water changes every 3 days for the past 4 weeks because the algae returns so rapidly. I have even done total blackouts which helped, but once I turned the light back on for 2 hours per day, for the plants survival, poof! the algae returned with a vengeance. I have become a slave to my aquarium, spending many hours per week battling this scourge. It will be a miracle if my plants survive, because they are all currently melting. Once this algae sets in it seems to be very difficult to overcome. I finally resorted to replacing this high intensity light with the old kit light that came with my aquarium and so far the algae has not returned. UPDATE #1: Customer service reached out to me several hours after posting this review and offered me an upgraded replacement that allows brightness adjustment in 24/7 mode or a refund. Customer service has been excellent. I am willing to try the upgraded light, since I was happy with the quality. Regarding the difficult programming of the light schedule, customer service sent me more detailed directions and is also willing to help program specific times if needed. This company has been very willing to stand behind their product, which I really appreciate. I will be happy to try the upgraded version.
Review: Light does in fact grow plants. - The light is great. It’s doing well on the 29 gallon planted tank I purchased it for. It has enough PAR to actually reach the substrate which is approximately 15 inches down in an 18 inch deep tank. I’m growing easy to medium care plants along with some floaters like “frogbite” and after only a couple days the plants are really looking great and more vibrant. Heat is minimal and timer was easy to set up. Anyone who says differently probably didn’t even bother to look at the instructions or is the type of people that should be supervised and wearing a helmet at all times.

## Questions & Answers

**Q: Is it designed to avoid promoting algae growth?**
A: Yes, the SR-657 aquarium light can be turned on/off at the time you set, and the 20 levels of brightness can be adjusted to effectively prevent algae growth.

**Q: Is the battery included? Do I have to use batteries? How long does the battery last?**
A: Yes, CR1220 batteries are included. The battery is only for memory function, and the LED light and controller can work without the battery. The battery only consumes power when power supply is disconnected.

**Q: Can this light help plants grow?**
A: Of course! The spectrum of this aquarium light increases the intensity of red and blue light, which is more conducive to the growth of rhizomes and leaves of plants, and promotes the natural circulation of the water tank.

**Q: I'm having trouble programming, what should I do?**
A: Tell us the lighting schedule you need (start time, end time, light color, brightness), and we will assist you in setting it up step by step. We usually reply in 12 hours.

**Q: I need to have the night mode start at 6pm but the number is skipping?**
A: The night mode can't overlap with day mode. The night timer will auto skip the hours that is taken by day mode. Please edit day mode timer first.

### ⭐⭐⭐⭐⭐ Excellent Light for Fast, Healthy Plant Growth
*by B***E on October 14, 2025*

I’ve been using this SEAOURA 24/7 aquarium light for a few months now, and it’s made a huge difference in my planted tank. My red tiger lotus and Rotala Blood Red have been growing fast and turning bright red under this light. The colors really pop at around 90% intensity, though I did have to lower it to 70% to reduce algae at that level. The controls are easy to use, the power off memory works perfectly, and the build quality is excellent. It even slipped into the water for a few seconds, and it’s still running strong 8 hours a day without any issues. For most planted tanks that just need a good full spectrum light, this one is perfect. The only thing missing is a custom color mode to fine tune red intensity for high red plants that would make it flawless. Overall, great value, great performance, and surprisingly durable!
