gassed my rasboras!
I've been steadily increasing pressurized co2 in response to curled leaves and other signs of co2 deficiency in my plants. Ordered a drop checker at work yesterday to monitor the ppm...
came home to an ALMOST gassed tank, with my harlequin rasbora's looking the worst of the bunch. Lost 3 of 5, but nothing else... CPD, habrosus, shrimp, etc all seem fine today. co2 must have built up slowly, even though I have plenty of surface agitation from a spraybar.
I thought it was unusual that the harlequins were the most sensitive, any thoughts?
