Birds nest die off
 

I've had two large birds nest colonies die off in less the a month now, and can't figure out why. A large brown, and a large pink. Had both colonies for well over a year. Within two days each, they completely die off. Whats up with that? The only thing i've changed, is the switch over to bio-pellets. Any Ideas?

Hmmm, I don't think its the Pellets, I run those without issue.

I find birdsnests like lots of light and heavy flow. At least for me... Did anything change in the lighting or flow?

If the only variable that was changed in your tank was the biopelets and than this happened i would be looking at this. Now here is what i have a problem with. With these biopelets did you dump the whole bag into your reactor or did you only start with a small amount?

Than again, in the spring my birdsnest rtn'd on me after changing 2 bulbs. you never know

Only started with half a bag of pellets. The tank is only 72 gallons. I don't believe flow or lighting are an issue. (well, at least i don't think they are). Both colonies were growing and doing fine. With any luck I should be able to frag off a piece of the pink. And i have a second colony of the brown. Dissapointing.

when you get home triple check your parameters. also are you dosing anything?

I'll check everything, and break out the frag tray. I'm using E.V.S B-Ionic 2 part system, And have been for a year or so. I have water gurgling, for a water change, as we speak.
