Oh thats a nice thought. I could had some CUC once I have algae bloom. Alage will act as a food source and in turn I will some ammonia.
I was planning to go barebottom this time. So instead I have 1 gallon Bio Spira balls for bacteria to flourish. I like the idea of getting coraline alage. I might pick snails which have them and they can seed

.
I have read that in order for coraline to grow they need calcium and Dkh. I am not planning to dose anything for now. I use Instant Ocean Reef Crystal. (I know I will switch it soon to better brand). I wanted to use that as I had it handy.
Do NOT use plastic bio-balls. You will end up with a Nitrate problem.
You only get Aerobic bacteria with those.
Snails will clean some algae, but if you have high Nitrates, hair algae will win.
Generally you need a Tang or something also.
Time for some test kits. Cheap API are fine for now. Never guess at Alk or CA.
But you probably do not need to dose anything for a while.
Nothing wrong with IO. It is WIDELY used.
There are better salts. There are more expensive salts. Not necessarily the same thing.
I use standard IO, not reef crystals, although I do add Mg.
