It seems like many 30 inch LED lights are too strong for a low tech planted tank. I'd like low/medium light just to grow some easier plants like swords, anubias, java moss, etc. What do/would you use on your 20 gallon long? Thank you

I have the AquaOne 13" on my 10 gallon low techs. Great (low tech) plant growth and no algae. Plus it makes reds on fish really pop. A 20 long is the same depth as a standard 10g.

I looked at your tank and its very impressive, looks awesome! I was going to ask if you use a dimmer or think that your Beamswork is too bright, but it seems like it works well for you. I actually have that exact light on my 37 gallon and have had mixed results. Do you use ferts/CO2?

So they aren't the fuIl span of the tank obviously but I like some shadier spots for the fish.

On a 20L I've also run the Marineland LED 24" (I think)-they don't make it anymore. I liked the low profile and it kind of acted like a shelf during maintenance and pruning. But I always had algae issues no matter what I did.

My 20 is dirted and i don't use a dimmer and I haven't had too much algae other than a little green spot here and there, which my shrimp and snail quickly handle. But i planted very heavy to prevent huge algae growth. I only use Thrive 1x week after a 50% wc.

It's is a very bright light, and i've started to add some floater to encourage some of my more shy fish to come out, but not because of any algae growth.

Look into the finnex stingray. Excellent for low/medium light plants in a 20g.
I've heard great things about these, but wouldn't it be too bright for a 12 inch high tank? According to: the stingray would be high light.
