I did two treatments about 30%over dose, I was ready to do a third but monitored and wasn't needed

here are my final notes
Final log notes
I’ll consider this a very successful Red Bug treatment
Beginning notes
• I suspect I got the Red Bugs on a mail order coral that I got in May of 2007
• The red bugs were first noticed by an experienced reefer during one of our clubs tank tours in June 2007
• I never did notice them on other corals, but it was pointed out to me when I sold some extra frags that they had Red Bugs.
• Started to read as many forum write ups on treating for Red Bugs using Interceptor. I was getting several variations to the original plan so I started asking questions on the forum. It’s the start of this post.
• Decided to start the treatment with hopes to do it once, but based on feedback I prepared on doing it three times.
• Started to remove crabs the week of 12/21 from my reef tank and moved them to the 29g seahorse tank. Getting an Acro crab out was a concern, but between staying in water and a little coaxing with a toothpick he decided what was best for him. The best I could tell I got all but 3 hermits out.
• Made a couple attempts at getting the shrimp out but they are much faster and spook much easier then hermit crabs.
Started first treatment on 12/28 at 9:50
• I used 1 full sized tablet, enough for 380 gallons according to the initial recommended dosage. So based on a rough calculation of my systems total volume I estimated I overdosed by 35% (380/280, the 280 is based on 280 for main, 40 for sump and piping, less 40 for volume taken up by live rock)
• I also planned on running the treatment longer then the initial recommendation.
• Turned off skimmer air & ozone, removed my carbon and phosphate reactors and drained them. All other piping was open to allow flow throughout the system. I crushed the tablet using a spoon and plate and mixed it in a small container with tank water. When dissolved, I poured the mixture into my sump into the high flow area just upstream of my return pump.
• Monitored red bugs and shrimp about every 2 hours. Taking progress pictures that are posted in this thread.
• I’d say 75%+ of the red bugs were gone at the 4 hour mark, with over 90% gone at the 10 hour mark. One showed up at the 12 hour mark.
• Everything looked clear at the 14 hour mark. I started fresh carbon and skimmer after 15 hours form introducing the treatment. I hooked up the phosphate reactors later that day.
• All shrimp and the purple lobster survive, lost 2 hermits that were not removed earlier.
First week after treatment observations
• Nothing noticeable for first 3 days
• I tested water on day 2, nitrates were up a bit, but no big deal. Notice Iodine/Iodate were low so dosed with Lugals solution. A couple of the shrimp molted that night, this may have helped them get through the second dose as from all other posts I have read the second dose is usually too much for them to handle. I’m noting this for others, they may want to incorporate it into a procedure they use with shrimp in the system. I think I just got lucky as it was not a planned event.
• Day four there appears to be a couple small white spots on the coral that had the worst infestation (all other corals appear clean). At this time not sure if they are Red bugs or something else. They are about 1/3 the normal red bug size.
• Day five, several more white spots noticed, about 5 in all, and they appear to me moving based on camera shots. Under the camera lens, a couple of the larger spots have a yellowish hue. At this time it is suspected they are new offspring red bugs. I have no clue if these are from a live parent that gave a recent hatch or what.
• Day 6 and 7, more spots and looking more like young red bugs. Decide to go with second treatment. Concerned about shrimp.
Started second treatment, 8 days after starting the first, on 1/6/08, at 10:30am
• Again turned off skimmer, ozone and removed carbon and phosphate reactors.
• 4 hours into second treatment all red bugs appear to be gone. No other bugs show up during the remaining treatment duration
• At 7:00am or 20.5 hours into second treatment I started the carbon, phos, and turned on the air to the skimmer. Apparently no impact to shrimp all accounted for that day doing there normal stuff.
• Changed carbon and did a 10% water change that night.
• Visually inspect and take close up photos of corals, nothing noticeable is observed throughout the week. Assume all red bugs have been eradicated. With the shrimp still alive success is clamed.
• Later that week, reintroduced most of the hermits and acro crab. No ill side affects noticed.
• Plan on doing another 15% water change this weekend (a week after second treatment) and reintroduce the rest of the hermits that were initially removed.
Other notes:
• The mid way iodine dosing was pure coincidence, but I think it may have helped the shrimp survive,
• At least one hermit survived the ordeal, two did not (may have been other un-noticed).
• A barnacle on a coral appeared totally unaffected during treatment. As these are considered a crustacean, I am noting it here.
• Polyp extension during treatment appeared more then normal. This was also observed in other posts.
• Nitrates slightly elevated, suspect it’s related to lack of cleanup crew and pod die off.
• Pod levels decreased significantly. None observed a week after second treatment. Will re-introduce from smaller seahorse tank that has a high population of various pods. May consider buying some new fresh live rock to help with pod population and other biodiversity.
