Now I may only be 3 yrs. exp. in this hobby, and run things a lil' different than alotta people (the oxygen carrying capacity of the water tends to drop a bit at 5,000 ft., kinda like the air), but I do know the lil' white spots on the fish are EGGS. Thousands of ick babies (around 12000) on roughly a 4-6 hour hatching cycle, time is key! My Desardini tang is now beginning to get signs (fading and lacadasical) of illness. Ick is a disease that is present in each and everyone's tank here. It only gets brought out in a time of stress (fighting, NH4 NO3 rises, severe temp. changes are just a few). I'm not tring to be an ass or anything Beth like i say i'm new. What, by the way, do FO & LR mean? I and alot of my customers have tried Quarentine tanks (QT, right?) with suprisingly poor results. Lots of clouded eyes and ick, Amm. rises within the two 1/2 to three week time and shtuff gets funky. Dip and drop has worked so well (straight to the tank, no acclamation, why add to the stress going from this water for three weeks and then start it all again when you put him in the "show" tank (dif. levels, dif. establishment times, totally dif. tanks=STRESS) Thank you for your help, please write again.
