If you are satisfied with the Growstar, slap another on...
Another growstar? Fan noise may become prohibative. The marineland does not have any fans and worked as well for me. .02
I have looked at this light but I don't know.
CREATE BRIGHT Led Grow Light Bulb, 28W Plant Bulb Full Spectrum Led Grow Bulb E26
I can not get the url to copy so go to amazon and search for Marineland led aquarium light 11 inch for aquariums up to 30 gallons.
It is not expensive either. I was surprised when it grew chaeto better than my 54 watt led plant light I bought on Amazon.
Huh? I'm curious why the fan noise may become prohibitive...
...it's not like they are going to get all liquored up and start yelling at each other over doping in Olympic doubles curling or something. Wouldn't two 30 dB fans remain 30 dB?
No the noise is additive. Would be twice as loud. I read that a guy swapped the fan on his with a computer fan that was quieter.
Another Growstar may be tooooo much light for that space.
I'm looking at these lights...
The Growstar has proven that expensive does NOT mean the best.
I think lights 1 and 2 are pretty much the same light so saving a dollar or two is a good thing if they would work. The other lights are slightly more powerful (So they say)
Well, the things we learn on Reef2Reef... Google, once again is our friend.
I was interested to learn, that yes you are technically correct the sound is additive, however it is not twice as loud.
Apparently doubling the source of the same sound will increase the overall pressure level by 3 dB, independent of how loud the source is to start with (i.e. 30 dB or 120 dB).
This site had the math: https://www.engineeringtoolbox.com/adding-decibel-d_63.html
I also learned that 3 dB is at the edge of being detectable by the average human - what several called JND or Just-Noticeable Difference (i.e. could be detected 50% of the time).
Given that dB's are logarithmic (I actually knew that one! ) and a whispered conversation is 30 dB, I think we can debunk that a 3 dB increase is "prohibitive" to the average individual.
There may be other reasons not to double up as the OP responded, but sound shouldn't be one of them.
I have an Eshopps R-200 sump and it works fine with the Kessel 380.
