Just did a water test, so just for fun, I will let you vote which one has the highest reading of Ammonia, Nitrite and Nitrate. All of them had 90%WC (because of substrate) on Tuesday night, and today test was at 1PM, Thursday, about 1.5 days...
Have fun...and feel free to post why you voted the way you did. Answers will be posted later this week.
