A lot of people find they lose their shape under less intense lighting. Metal halide seems to keep the tips better.

Most BTAs I know of lose their "bubble tips" eventually.

No one knows..... mine doesn't have them either. Doesn't mean they aren't doing well though.

My old BTA was ~4-6 inches under a 250w MH and it barely had any bubbles :confused: . It was quite healthy though, until it got sucked into the drain and chopped up by my skimmer :eek:

What kind of light is it under? How deep in the tank is it?

FWIW, under my PC's on my 20g tank (2x65w) I used to see some bubble tips on my RBTA... I have since switched to MH (150w HQI) and I haven't seen any bubble tips since ...

like I said, FWIW !

Mine bubbles sometimes under my 2x96w PC's, and I'll find out this afternoon what it does under 4x39W T5's.
