Algae question

[Yclam]

My tank has been cycled for over a month and now I have the normal diatom phase. Today I came back from work and I now have green spots appearing all over. Can someone tell me what it is and what I can do about it?

Part of the process, no worries

For the diatoms just let them run their course. Nassarius snails will eat detritus and uneated food, not algae. You can start to build up a good mixture of snails to tackle different algae strains, but you want to build the population up slowly so they don't starve themselves out!

I would research clean up crews in general, it's a good idea to have a good variety, just take it slow.
