Light height - Fluval plant 3.0

My fluval 3.0 sits very close to the water, meaning light is much stronger in the central strip than at the front and back of the tank

Has anyone experimented with raising the height of a unit like this? Is it worthwhile? Easy to do?

I've got a bit of BBA forming in the centre, where the light is strongest, but my background stem plants have a tendency to lose their lower leaves despite full EI regime in a low tech setup. Wondering if more even lighting would help

I actually got for some acrylic cut to the height i wanted and screwed them into the sides of the extendable arms, imagine "ghetto twinstar style". Then i cut a triangle shape out the bottom of the acrylic so they would sit and stay on the glass rim/hood

Hi, did you sort out your issue as I feel, I'm in a similar predicament. Plenty of growth but few leaves at bottom. M light is about 50 mm from surface of water

Well I've got it jacked up on two drinking glasses for the moment - will see how it goes. The tank's got a perspex cover so it's an easier bodge than for an open top. If the plants respond then I'll do something more pro. Or buy new glasses at least :)

With tanks that wide, I use two Fluval 3's to get full coverage. I don't think the lights are powerful enough to elevate them over the tank.

Love it. I have done a similar thing, light is now 150mm above water surface. I'm going to monitor things for a few weeks ie plant growth and any algae issues. I also have an acrylic top so need to keep the ultra clean. Thanks for getting back to me 👍🏻

Thanks - I'll see how it goes. Still only at 60percent...!

I ran the Fluval plant 3.0 on my first scape, I found with it sat on the glass it didn’t give enough spread, I raised it with the fluval hanging kit and ran it at 100% on all channels, soon after I upgraded it to a twinstar 900S and it was a massive improvement
