6 months tank, fallow period. Spot algae, coralline...

Alexz · Oct 1, 2021

Hi. I’m not sure how go about this algae issue. So it definitely looks like I’m finally getting coralline algae on my rocks and glass. But also spot algae and other blurry greenish algae not sure what it is. Especially on the low flow side of aquarium where corals are. So obviously I need more flow on this side. I read that you’re not supposed to clean coralline algae from glass if I’m trying to get my pukani rocks to finally cover in it. So in my case I should clean all this algae along with a dozen coralline spots on glass and just let it grow on rocks for now?

I always scrape the coraline (and everything else) off my glass. Seems to have no problem growing on the rocks just fine.

I have a gyro on left side and 2 power heads on the right. Left side is where all the food settles. Should I add another gyro on the back panel on the left side of aquarium? Maybe even 2? Since my aquarium is 91x21x21. Thanks

You could try running the gyre on the left side in reverse instead of forward. The two powerheads on the right might simply be overpowering the flow and you're ending up with a recurring dead spot. On my 71" tank I have a ReefWave45 gyre on either side (3.5" from the surface of the water) that alternate between forward (8min) and reverse (2min), between 20-60%. A pair of Maxspect XF330s are on either side of the center overflow at the rear - facing towards the front of the tank (these just provide a fixed 10-20% forward flow).

Or it’ll be better if I add 2 more power heads on the opposite Side below gyro? Or add 2 gyros along back and 2 power heads on the opposite side? I done really want power heads on the left side since it’s the best looking side lol what you think? Thanks

Great idea! Thanks
