Buccal, you state:
I only suggested that a feel the garlic has made no difference for myself whether i used or not.
I put this up for discussion to as before mentioned learn between one another on these sites.
But clearly that is not all that you suggested, you made some rather bold statements that on most forums create knee jerk reactions by the masses before they realize the source of that information. This is why I am posting here, as I have when Wombat and others have used his silly little study in an attempt to convince the masses that garlic is somehow dangerous to ones fish, including ALL garlic in ALL forms and in ALL amounts. That's just idiotic!
Go back to page one and it seems crystal clear to me what you were attempting to do, and what you were stating, which was FAR more than what you say now.
It causes internal lesions to the fishes organs.
Yet that study has NOTHING to do with any of the commercial fish foods on the market, as none of them are adding a purified form of allicin, nor do they contain anywhere near the lipid content (which is what caused the lesions in that study) - hence that data has ZERO value from a fishkeepers perspective - unless said fishkeeper is feeding raw garlic to their fish on a regular basis - which is something I would never recommend, anymore than I would recommend feeding raw peas on a regular basis. (due to anti-nutritional matter)
You don't have to be a rocket scientist from NASA to understand this concept. Nor does one have to devote large parts of their life to obtain knowledge on these things, to understand this very very simple concept. The *study* that has been tossed around on a few forums over the years did NOT involve any brand commercial fish food on the market, and has absolutely NOTHING to do with ant brand of tropical fish food. Once again, this is like stating that Vitamin A can be toxic to a fish. We already know that - and your point is? Don't feed excessive amounts of Vitamin A to your fish. Doh!
Ronny got that straight away back on page 1.
In high amounts, yes it can be harmful as can anything in high amounts.
All the scientific supporters in the world won't change those simple facts.
It's like a wives tail belief that has turned into demand, and manufacturers are adding it for improved marketing,,,,,
Is this what you mean by sharing of information & learning from one another? Hmmmmmm. This is where I think it would have been proper to fess up from the start as to what your association with commercial fish food was, and the marketing of that food. You took a direct shot a your competitors, implying that garlic is only used as some kind of marketing gimmick.
Seeing as you have decided to discuss NLS, allow me to explain exactly how garlic ended up in their food, and why.
Pablo Tepoot, the creator of New Life Spectrum, has been using garlic in his farm feed since 1990, and while he has never set up a controlled group to study the cause & effects, he noticed a drastic drop in disease in his ponds since implementing garlic in his daily feed. Since adding garlic to his daily feed regime, he has not had a single case of what's commonly referred to as Florida Deep Well Disease. (disease caused by pathogenic bacteria Aeromonas sp. and Psuedomonas sp.)
At one point in his fish keeping career (late 1980's) Pablo had a case of Aeromonas sp./ Psuedomonas sp. in his ponds that was so bad he could not contain it with traditional aquaculature meds such as antibiotics etc. It seemed to be a resistent strain of bacteria (something now common in aquaculture) and he was at a loss. He was losing thousands of fish and eventually he had to drain his ponds and allow them to dry out for a few months. He literally had to shut operations down. In the end he lost 10's of thousands of fish, and decided to look outside of traditional medicine in the hopes of finding a more natural non-intrusive and "fish safe" treatment that could prevent this from ever happening again.
His search lead him to some people working in commercial aquaculture and trout, who were having success with the use of garlic in their feed. Even at very low concentrations it seemed to improve the fishes overall immunity to certain strains of bacteria. The combination of certain sulphur compounds found in garlic not only boosted the fishes overall immune system, there was no risk of these bacteria strains building up any kind of resistence to it, which is what was happeing with traditional medicinal treatments. Antibiotics were no longer working.
I have already posted this information previously, which supports everything that I have been saying, for years now.
Effect of Allium sativum on the immunity and survival of Labeo rohita infected with Aeromonas hydrophila

Summary
The aim of this study was to evaluate dietary dosages of garlic on the immune response and disease resistance against infections due to the opportunistic pathogen Aeromonas hydrophila in Labeo rohita fingerlings. Garlic, Allium sativum, was incorporated into the diets (0%, 0.1%, 0.5% and 1.0%) of rohu, L. rohita fingerlings (10 ± 2 g). Every 20 days, different biochemical (serum total protein, albumin, globulin, albumin : globulin ratio, blood glucose), haematological (WBC, RBC and haemoglobin content) and immunological (superoxide anion production, lysozyme activity and serum bactericidal activity) parameters were evaluated. Superoxide anion production, lysozyme, serum bactericidal, serum protein and albumin were enhanced in garlic treated groups compared with the control group. After 60 days, fish were challenged with A. hydrophila and mortality (%) was recorded up to day 10 post-challenge. Survival decreased in control group (57%) up to day 10 after infection. However, this was increased in the garlic treatment group, i.e. 85% survivability in the 1 g garlic kg−1 (B group) and 5 g garlic kg−1 (C group), and 71% survivability in the 10 g garlic kg−1 (D group), respectively. These results indicate that Allium sativum stimulates the immunity and makes L. rohita more resistant to infection by A. hydrophila.
Of course that is only 1 study, there are a lot more out there now for anyone that wants to do their own
research.
Here's a very recent study (2013) involving flatworms that took place in AU, at the School of Marine and Tropical Biology, James Cook University.

Garlic’s active component allicin does not leach from aquaculture feeds.
Abstract
Development of an effective preventative treatment for managing infections by Monogenea (Platyhelminthes) in aquaculture remains elusive. Present treatment methods offer only temporary respite and are either labor intensive, harmful to fish welfare or environmentally destructive. This study used garlic (Allium sativum) supplemented feed to assess its potential, in relation to its allicin content (an active component of garlic), to prevent infection by Neobenedenia sp. (Monogenea: Capsalidae) on farmed barramundi, Lates calcarifer. Two garlic supplemented diets of different concentrations and a non-supplemented control diet were fed to L. calcarifer for 10 and 30 days prior to challenging fish with Neobenedenia sp. Long-term (30 days) supplementation with garlic significantly reduced infection success by up to 70% compared to controls and did not negatively affect palatability of the feed. Infection success was not influenced by short-term (10 days) supplementation suggesting that a delayed host response must occur to improve resistance to infection. Incorporation of garlic into a pressure-extruded pellet was found to be an effective method of delivery as only minimal leaching of allicin from the diet occurred (< 3% of allicin detected) during the interval of water contact between delivery and consumption. This study demonstrates that garlic extract administered as a dietary supplement is one of the most practical methods to prevent Neobenedenia sp. infection in mariculture.

You need to drop $40.00 US to read the entire study, but you should get the overall point from the abstract. Clearly the use of garlic in aquaculture feed is more than just some marketing gimmick, at least to those who are serious about this hobby.
For those that don't want to spend the $40.00 US, but are interested in reading more about his particular study please see the following link.
Garlic Keeps Fanged Fish Parasites Away
“Previous research has demonstrated that feeding fish garlic significantly improves their immune system, we wanted to take this research a step further to examine if there was any medicinal effect against parasites” explained Thane Militz of JCU’s Marine Parasitology Laboratory.

As far as the danger of feeding foods such as NLS, due to garlic content - that's the only old wives tale being told here folks. lol
I have personally kept, and seen many more fish such as African cichlids that are 10-15 yrs old, as old or older than one would find in the wild, that have eaten garlic via NLS since the day they were born. Same results with numerous marine species - no longevity or health issues here - and unlike New Era, NLS can actually make claims such as that, as they have actually been in the fish food business for more than a few short years.
Now that we have cleared up the garlic fiasco, which is what this discussion was supposed to be about, I think I'll go back to doing what I do best - enjoying my fish and my family.
Take care all.
