Do yourself a favour, if you start seeing algae, either reduce your light period or reduce the number of white LEDs firing. It would suck if your dedicated algae eaters didn't like your variety of algae and it got out of hand.Oh don't worry! I'll definitely put them in one species at a time. Which comes first probably depends on how much algae I'm seeing once I feel then tank is ready for fish. Yeah the stalks are already splitting, they should have grown into healthy new shoots within a few days.
