I'm no biologist, so I'm just guessing I've never seen a case where ramshorns of just one color exist in a tank without ntervention. I've recently culled all dark red/browns shelled ramshorns from my tank. Let's see if the blues ramshorns continue multiply.

Is that a marimo you have in the tank? It maybe the cause of all the hair algae.

+1 on running both for at least a month The only drawback I see is the noise that most air pumps are noisy compared to hob and canisters filters.

Here's what I learned from a couple of years breeding blue ramshorns. 1. The blue shells are actually clear. The blue coloration comes from a combination of light colored flesh that allows their blue blood to show through. 2. The gene that shows blue ramshorns seems to be recessive. If you have a tank of blue rams they will also give birth to more red/brown shell colors more often then blue. 3. You can't tell color until young snails reach a size a bit larger then a bb pellet 4. Snails generally live 1.5-2 years. On very rare occasions will get a pretty violet/purple or bright pink ramshorns.

Isn't this just gel food like Repashy on a bamboo skewer?
