co2 and pearling?


OK I have the fluval 88g tiny tank set up.ceramic diffuser. With a power head pushing all bubbles downward and around tank. They DO stick to plants. I've watched for hours pearling but not from oxygen. Is from co2 I have a hob filter 440 emperor that pushes water across and down so bubbles never make it to surface. Is in a 30 gallon cube 20/20/20. I'm not understanding this pearling talk cause I've watched my tank co2 never get to.surface unless 1 thousand times smaller than they started and are invisible. My power head has bubbles my inlet on filter has bubbles. I really don't understand this. What is the temp you guys run for tanks and plants. I have mine up to 85 so I understand cooler water more dissolution of co2.

The co2 is sticking less to plants than u think. A lot of the bubbles u are seeing on the underside are oxygen.. i run a co2 mist and if i dont have it high enough, i dont get bubbles, but u can clearly see that im spraying a mist everywhere

I can't quite make out what you're asking. Are you wondering why your plants won't pearl? I use a reactor & I don't see bubbles go inside the tank however I do see bubbles forming on my plants leaves. 85f is pretty high, what plants are you keeping? I'm at 72-78f

Yeah I know temp is high lfs and ick. Right out the gate. The bubbles from co2 make it around my tank in a circle at least 2 times maybe due to high temp low dissolve. But I've seen the bubbles stick to my plants and build up. I have 13 different types of plants and intend to keep them perfectly trimmed as I'm a landscape biz owner for long time now I realized that perfect shape and size to bush's/ plants takes year.

If its the co2 bubbles. They will be top to bottom.. pearling will be on the closest leaves to the lights depending on how intense ur lights are..
That is ur variable.

Not sure what the question is. Bubbles on the leaves surface and edges usually is oxygen what we call Pearling. The plant is giving off oxygen through photosynthises when light and carbon is in the tank. Co2 will sometime get trapped under leaves but should not be sticking to the surface of the leaves. How about try this tomorrow morning turn on your co2 but not your lights. Leave lights out but co2 on. See if the what you think is co2 begins sticking to the plants. I suspect you will not see this happening that would suggest it is oxygen not co2 your seeing.
