Plants not doing nearly as well as they used to

Could the substrate be getting too old (ie: compacted, depleted of
nutrients, etc.)?

Actually, I'm afraid I don't have an enriched substrate. I only have regular
gravel. Not ideal, I know, but my plants nonetheless used to do a lot better
in the past.

In any case, thank you for the suggestion. I'm sure it can benefit people
who do use special substrate, or even myself if I decide to use it. I just
might. Thanks for the idea.

I'm absolutely traveling to do something about that soon. I'm absolutely annoyed about the abridgement of light, not alone for my plants but aswell for the so-so aftereffect on the fish. There's alone a actual baby breadth area they attending nice, the light refleclting on them in a affable way. Elsewhere they attending rather dull, unless I move the lamp around.
