Chaeto producing bubbles and extending

[cwk84]

I recently started the Triton method with a v22 sump for my 75 gallon tank. After 1-2 days my chaeto started producing a lot of microbubbles. I've had an algae reactor on my old tank and the chaeto grew like a weed but didn't produce any bubbles. Are bubbles just a sign of it producing oxygen or am I facing a possible nuisance algae outbreak?

That means the chaeto is happy. In freshwater planted tank it's called 'pearling'. Basically your chaeto is photosynthesizing so fast that the oxygen released doesn't have time to dissolve into the water before it forms a bubble and is released into the water. Doesn't mean oxygen isn't being dissolved into the water. The bubbles are basically excess oxygen.
