Hello.

I am assuming this is algae growing on my aragonite substrate? It’s only in certain spots where they are landscaping high points. I give extra attention stirring/vacuuming these areas during weekly water changes. It doesn’t seem to be getting worse but should I be doing something to stop it now? Definitely don’t want it to get out of control.
The tank does get some morning sunlight. I’ve stopped using the lights 100%. There is no algae on my glass. All inhabitants are healthy

Thanks for any advice.

Wow, that is one seriously deep-looking aragonite substrate bed!
I'm guessing that the algae is forming up on the glass and aragonite rocks that face the sunlight? And yes.... that would be kind of a nuisance to clean that sort of thing, as you have to dig down into the substrate to get at it.
So, ideas?
- Maybe use less aragonite so it isn't as deep and piled up so high on the glass?
Full Disclaimer: I've never used aragonite as a substrate in any of my tanks.

• Replace the aragonite with pool filtration sand?
• Install a black masking strip (approximate thickness of the aragonite substrate) across the front/bottom of the tank, and don't worry about it?

I agree with making the sand not so deep. But likely it is growing on the glass areas and not throughout the substrate. Just keep siphoning.

Actually beneficial to your tank.

Thanks all. I’ll remove a little substrate with each water change. To be clear it’s not this deep throughout.
