Sentinel for red bugs

bubblewood said:
How is the treatment going for you?? Please let me know your thoughts. I have a 240 gal mixed reef. I have the red bugs on some of my acros. I did a Bayer dip last night. I feel I should treat my entire tank for peace and comfort.
Thanks!

Will let you know. Have another hour before I start WC's and run carbon.
 
Thanks! Makes me very nervous doing this treatment. Sure it does for you too! Any noticeable differences with anything in your tank?
 
Nothing to be nervous about. People have been using Interceptor and Sentinel for years with great results. It is very gentle as far as any reef treatment can be.

It will not kill any fish.

This is not completely true, as meds that kill copepods can indirectly kill fish. I had a friend who lost a mandarin and I lost a dragon face pipefish due to treatment with Interceptor, both of which were doing very well prior to treatment. Since the active ingredient is the same, I think the same results should be expected with Sentinel.

I believe that these fish ate pods that were dying or already dead due to the treatment, and by ingesting these pods they may have been poisoned as well. Death for both fish was immediately after treatment. Regardless, these types of fish will starve to death since they no longer have a food source.

My advice--if possible--is to remove any fish that eat pods almost exclusively. You will also need to consider other food options for these types of fish since once returned to the tank, the pod population will still be re-establishing itself. The best bet is to train your fish to eat other foods. In my case, my pipefish was eating frozen cyclopeeze, but still died.

The best course of action would be to set up a small tank with rock and pods prior to red bug treatment, with the intent of breeding the pods (buy a starter culture, or ask a buddy for fuge water with copepods, amphipods, etc.) and also giving your pod-eating fish a place to live while the tank is undergoing treatment.

Thank you for the correction. I haven't seen any fish deaths or read about fish problems from the other threads. I might have missed it.

"FAILURE!!" Crabs are dead but not the bugs!! Alive in all my systems :9( "Now What?"

If it killed crabs I am not sure how the bugs would survive. I have seen crabs that survived but the red bugs were definitely dead.

Are they moving still or just the bodies left over? Good water flow should be maintained and would have blown them off.

What you state is most likely true (injesting treated pods). I did not remove my Mandarin so time may tell. He's been a healthy, heavy guy for years! He does eat other foods so that's why I wasn't too concerned but now, in hindsight, maybe I should have:facepalm:

I have no clue either Tek! All crabs were dead but 1...it was barely moving and died shortly thereafter the 12hr treatment. The red bugs were/are moving. I believe I saw a few that were dead but still attached to the underside of frag plugs. I also saw a few 'live" amphipods and (good) copepods. Those were easily visible in the fuge as well as 1 mini brittle star still alive in chaeto. I did find several mini brittle stars dead and other 'arms' moving in the current. I am unable to ascertain how many may have died as I cannot see any in the water column, floating on top the water, etc.

Although it may not have been the right thing to do, I again repeated the dosage "without doing a water change":rolleye1: If I had to venture a guess, I believe I did not add enough Sentinel to the systems-especially since each tank still had live RB and dead crabs and mini stars. Taking that under consideration, I found that hard to believe as I used one Sentinel for systems having 250g TWV combined!! :hammer: If I under-dosed, I am hoping this second dose (equal to the first) may kill the bugs-that is, IF, the Sentinel ingredients remains active in the water from the first dose.
I plan to do a 25% WC on all tanks at the 10-12hr mark with the second dose. This is bizarre but with my luck, right on target:fun2: Today is this 'ole woman's birthday and I'm hoping to have a great ending to this day--DEAD RED BUGS!" I'll let everyone know! :thumbsup:
 
Just finished with WC's and with lights off, I will look tomorrow to see about RB's.

When doing the 135g tank's WC, I did see a scarlet hermit crab that was alive. It is a big one :0) I will see if I can find it later today. I will also be looking to see whether there is better PE on the corals. I hope so!

Thinking last night, I'm wondering about the possibility that the RB's are maybe becoming resistant to the Milbemycin Oxime? Since there are many more reefers, vendors and retailers in SW than there were 5-10yrs ago, if RB's have been a 'common' pest and treated with MO, it could be a possibility? I have no substantiation but it could be possible. It would be interesting to know how often this treatment has been used in the past 5-10yrs.....
 
I am surprised if any survived unless it was underdosed. Seems to have worked for most people and usually came back if the 2nd or 3rd treatments were not done due to eggs.
 
I know. I may have underdosed but I really find that hard to believe, especially since I did a second Sentinel tab. I have seen a few RB's today...alive. Also a few crabs but they are not doing well. Mini stars have continued to die throughout the day. There is better, but not normal, polyp extension on some of the Acro's.

I plan to treat again in a week. This next time, I will follow your previous suggested dose: 1 Tab for the 135g system. 3/4 Tab for the frag tanks (shared sump) and 1/2 Tab for the 40B system. I have asked my Vet for more Sentinel as I only have 4 Tabs left. Again, thanks Tek. I shall return for an update after the second treatment!

Busy day today but did sneak a few peeks at frags/plugs that had RB's on them previously. None seen :0)

Success! The improvement shows in a few days and within 1-2 weeks. More PE, better color, growth. :beer::beer::beer::beer::beer::beer::beer::beer:
