Well now that interceptor is officially discontinued and sentinel is on the shelves I was wondering if anyone has been using it and if so what have you noticed?
I decided to be a guinea pig myself about three weeks ago. I stopped at the vet and got two of the larger tabs.
I like to dose my Qt tank pretty regularly so I figured i'd see if this stuff was a safe useable alternative.
In case you are unfamiliar with sentinel it's basically interceptor with an added ingredient to help control flea eggs called lufenuron. The large tabs contain 23 mg of MO(interceptor) and 460 mg of lufenuron.
Roughly three weeks ago I decided to dose my qt with one half of a tab. The system is about 70 gallons.
First thing I noticed is that the sentinel has a coating on the pill and that it crushed up pure white as opposed to the familiar brown. Without hesitation I dumped it in.
I should mention that I this system does not have any red bugs in it at all. This has been mostly an experiment on weather sentinel is safe as opposed to effective, which i'll touch on soon.
The treatment was pretty standard. I saw nothing outright that would let me think the lufenuron had any immediate bad effects.
I left the tab in with my skimmer off overnight. When i turned it back on it overflowed for a long time. I ended up turning it way down for a day for so.That was a significant difference. With interceptor the skimmer would skim a ton out right away but never actually overflow.
I have a few resident hermits that I would take out when I dosed interceptor. I left a couple larger ones in and some smaller red ones. Interestingly they all survived the treatment. I am a little concerned by this.
Fast forward a week. I dosed the other pill but this time I rinsed the coating off.
Treatment was the same. All the crabs survived again.
No ill effects on any coral, just unfortunate that I couldn't confirm that it kills RB.
Using the old 23mg interceptor tab would wipe out any small hermit with in hours. I was not really using this test to see if it kills the bugs because I know Interceptor does at that strength. Or at least it used to. For whatever reason 23mg of the same active ingredient left the crabs seemingly unaffected.
At this point it's been about three weeks and the thank seems fine. No mystery occurrences or coral deaths at all.
If anyone has tried sentinel or plans to, please share your experiences.
