"I bought a 30" planted plus for my 29g. First time setting up a planted tank. With a glass cover, would I still have to raise the light to help avoid algae?
Here I was thinking it would be too little of light? Not planning on running CO2."
This would greatly depend on how many plants are in the tank. My tank was lightly planted. So, yes I got algae. I started with the 36" planted + raised 6" over a 29 gallon and gradually lowered it as I filled the tank and those plants grew. Now that same tank is FULL of plants, Ludwigia Repens X Arcuata a glowing bronze color, red under the leaves. Limnophilia sp wavy trying to push the glass up, and a bunch other odd highlight plants doing well with the 36" Finnex FugeRay planted +.
