This blog post deals with a product line that was well known by most professionals in the aquarium industry going back to the 1970s.
My mentor in aquarium design, maintenance, & care was heavily mentored by the scientists who developed this line of products for aquarium conditioning and disease treatment/prevention.
Unfortunately this line went away around 2003, but thankfully this line has been mostly been brought back as “AAP Professional Treatments”

I will not provide a link as per my policy of not linking to selling pages, but it is easily found in searching the internet, just be aware that their are still some sellers of old product via discount outlets. So look for the ONLY online seller of “AAP Professional Treatments”
I will also “borrow” (copy & paste) some information from AAP Professional Treatment’s website to make writing this blog post easier/quicker.

A few highlights of products from this line that I personal use professionally:

• AAP Res-Q & Shieldex.
  This are two of the best water conditioners available that I would ad to a short list including Seachem Prime.

  AAP Res-Q is the ultimate water conditioner when fish have frayed fins or have visible abuse. A most effective product with seven way action. RES-Q detoxifies and conditions water by polymeric complexing (bonding) of metallic ions. Coats the fish with a slippery medicated bandage, balances osmotic processes, removes chlorine, clarifies water and aids in safe shipment of fish.
  Res-Q does not color the water.
  Used in lieu of other water conditioners if medication on the fish is indicated such as after injury or introduction of new fish.

  As per AAPs founder who has used this product in 1000s of professional applications, Res-Q is excellent both as a first aid and a water conditioner of choice when minor injury is present. It can also be directly applied via new fish introduction, as well as netting or “cupping” the fish.
  In our founders controlled test, the use of Res-Q improved the results of Super Ich Plus and sped healing of minor fin & body damage as compared to Stress Coat which had zero effect.

  AAP Shieldex is a Vitamin E fortified protective, stress relief and disease preventing slime coat treatment for ALL fish (freshwater/saltwater).
  As per AAPs founder, whom has used this product & similar products in large quantities in his 1000+ aquarium maintenance business, Shieldex is far superior to StressCoat. For one it allows for more natural slime generation and does not tend to “blob” on the bottom of the tank.

  Shieldex has a specific use when setting up a new tank. Nitrifying bacteria enjoy clinging to the slime coat it produces. Success in cycling tanks has been achieved by squirting the liquid directly into the filter bed prior to adding water.

• AAP Dyacide (Dylox).

  This is an excellent substitute for Clout.
  AAP Dyacide treats: Gill Flukes, Anchor Worms, Fish Lice, Parasitic Copepods, Pinpoint Sores, Tricodina, Monogenetic, and Digenitic Trematodes.

• AAP Spectrogram.

  This is THE ORIGINAL Columnaris treatment that is still superior to purchasing Kanaplex and Furan 2 separately

  AAP Spectrogram is the widest spectrum, gram positive and negative medication treatment available in the industry. It is indicated for all persistent or undiagnosed conditions (other than parasitic infestations).
  Spectrogram is MUCH easier to use than the traditional Kanaplex/Furan 2 combination as there is no conflicting dosing schedules which also allows for this synergistic combination to work MUCH better since both antibiotics are required at THE SAME TIME for optimum results.
  As well this blended combination overcomes the draw backs of using Nitrofurazone in higher pH aquariums
  Far superior to Maracyn II too.
  For ALL fish (freshwater/saltwater)!

  AAP Spectrogram is the treatment of CHOICE for Columnaris!! More effective when already combined, as well as this product being pharmaceutical grade. Why settle for less for your Columnaris treatment or Aeromonas Treatment too?

• AAP Super Ich Plus.

  AAP Super Ich Plus is second to NONE as the most effective freshwater aquarium fish Ich treatment with its unique/synergistic Malachite Green/Quinine combination

  AAP Super Ich Plus is an effective external treatment Freshwater fish for: Freshwater Ich/White Spots (Strongest available choice!), Scratching & Darting, Collapsed Fins, General external parasites

• AAP Wound Control (Merbromin).

  This was a product that made my “Fish Doctor” calls more difficult until AAP Professional Treatments brought it back as it was and is an essential part of fish treatment that there was NEVER any true substitute for; not Methylene Blue, not Potassium Permanganate.

  AAP Wound Control/Merbromin is a swab or paint-on disinfectant with PVP emulsifier for: wounds, scrapes, and abrasions as well as opportunistic bacterial infections that often result from these problems.
  A scrape against rocks or a bite on the scales can result in a serious infection. The simple process of catching the fish and painting the affected area will often prevent more serious problems or aid in an in tank or hospital tank treatment with antibiotics for more serious infections.
  As well, a direct swab of Merbromin has been very helpful from my experience for Columnaris external lesions of all kinds, except for those within the gills. The effectiveness of Merbromin lies in the fact Merbromin is an organomercuric disodium salt compound and a fluorescein that is effective on external infections because of its permanence, and lethality to bacteria, IN PARTICULAR COLUMNARIS!

• AAP Discomed

  AAP Discomed is a unique anti-parasitic (internal & external) medication to use to make a medicated fish food for Freshwater and Marine aquariums.
  Specific Treatment for Cichlids suffering weight loss.

  For treatment of Nematodes; Including Camallanus, Capillari, & Eustrongylid
  Treats parasitic causes of Color Loss, Weight Loss and Wasting, Darkened Body Color, Skinny Body, & Concaved Abdomen

• AAP Marex

  Another product that there was really no good replacement when it disappeared from the market in 2003

  AAP Marex is a colorless antibiotic blend of Pyrimethamine and Chloroquine Phosphate. The first effective copper substitute treatment Marine/Saltwater Oodinium.

• AAP Myacin; Superior Erythromycin Phosphate Treatment

  While API and Mardel provided Erythromycin products, these were inferior Erythromycin sulfate products.
  AAP Professional Treatment’s pharmaceutical grade Erythromycin Phosphate is a superior product that is stronger and more wide spectrum.
  Only a fool would purchase one of the others with this product now available!!
