Urchins

[jacobus]

hi guys .... just wanna ask if urchins are good for this job. and which urchins are not good for reef ...

[Metabolic_7]

urchins are not that of a clean for algae.sea hare is better

[Panzz]

some do, but most clean up your coralline algae instead which is wat we want to keep!

[ervine]

mine cleans up only coraline.. but that's fine for me, got lots to spare...

[andysho]

yep they will clear up coraline

thats wat i love

i have too much of coraline on my glass

too much make the tank looks purple

[FuEl]

Too much coralline is a headache once they take up all the calcium and carbonates in your water. Imagine your calcium media in the calcium reactor being used up mainly by coralline.

[andysho]

yep i used to love coraline

but now i hate them

[jacobus]

then wat do i use to clear off the algae tt grows on the glass ? limited to turbo snails only ?

[Panzz]

any herbivorus snails will help in the controlling of algae.

another suggestion is that instead of trying to control those algae that are growing, why not control those nutrients that is allowing it to flourish, such as reducing the levels of NO3 and PO4. This way you will not have any more possible outbreaks of algae and they will grow at a slower rate and then even with just one snail(depending on your tank size) algae will not be a problem to you.
