Bacterial Blooms


 - High additions of carbon sources at once are noted as production of slimy white strings upon rocks or in sumps that become noticeable a few hours to a day after addition. There is no clear evidence that this is detrimental to your tank. If this is observed dropping your dose by 50% will result in the disappearance of these strands. Additionally, these strands may have given rise to the notion of "bad bacteria". By this forum users mean pathogenic bacteria. But there has not been any documented evidence of such yet. If you happen to overdose your tank with an organic carbon dose, you will stimulate a bacteria bloom, this appears like a snowstorm in your tank. After a day, the tank will clear up. During this time people have reported mixed results on survival from this snowstorm. Stony_Coral has purposefully caused this on one tank and while ORP readings dropped, no loss of livestock was observed. However, people have mentioned loss of more delicate fish such as anthias during the visualized bloom. In general, a visible bloom will not occur if vodka is dosed as per the instructions above.
