How much do snails, shrimp, and algae eating fish help?

Let's say you're lighting is high for the amount co2(or lack there-of), and ferts in the tank for your plants... and then you start getting algae.

If the lighting is not "overly" higher than it's supposed to be in a low tech, do these animals help keep the algae in control? If you had lots of mts, dwarf shrimp, and otos or cories... would the high light in a low tech still produce significant algae problems?

Dwarf shrimp and ottocinclus are amazing.

They're fantastic, but not miracle workers. I have shrimp and otos n one tank and shrimp only in another and they tend to keep the algae at bay, some more than others.

For instance I have almost no diatoms in either track despite having intentionally introduced then (small dusty looking sinking balls from a lake) and u have almost no green hair algae either. But they tend to ignore black hair and green spot algae unless the shrimp get desperate.

IMHO is worth having some of each in your tanks, if for other reason than they are another link in our micro ecosystem and diversity is a good thing.. Same as micro fauna being good to have

Hi, they can be a great help but the aquario will have maintenance to do anyway. Water changes, glass cleaning, etc.

They eat some algae, do not touch others, one week they will eat a lot, the other week they may eat a lot less, etc.

High light in a low tech will cause algae almost immediately. I made the mistake of running my ecoxotic e series at full power for about 18 hours straight. About 180 PAR when I needed 40. My driftwood was starting to turn green. In less than two days.

If you're having algae problems you likely have too much light. Just raise your light a bit and you're good.

But to answer the question, different algae eaters are good at different things and you'd do well to keep more than one. They do help, my shrimp keep the substrate looking brand new.

To clean up algae and keep plants and hardscape clean, shrimp are best.

To clean glass you'll want snails and/or Plecos or Otos.

Also, to clarify something... cories are not algae eaters, at all... so have no impact here. Otos eat algae, not cories.

Cories are bottom feeding omnivores with a strong carnivorous leaning.. They'll clean up your leftover fish food, but their algae consumption is pretty much zero.

Thanks for clearing that up.
