  • Formulated by a marine scientist.
Technical Overview:
Experienced hobbyists are well aware of the delicate nature of the soft tissue that constitutes the living coral polyp, particularly in the case of stony corals. Inspection of a bare stony coral skeleton often reveals a very convoluted and sharp structure; when coral tissue is inadvertently pressed against such a structure, the resulting local tissue damage can create an entry way for infection and/or infestation by organisms that would otherwise be combated by the coral’s immune system. Physical damage to coral tissue is not an uncommon event during shipping and/or handling, and is an unavoidable result of fragmenting when the cutting site is not bare skeleton (again, in the case of a stony coral; cutting soft corals and polyps will always result in tissue damage). A colony or individual may also experience stress as a matter of changing chemical or physical conditions in the aquarium, often leading to weakening of the immune system, with the afore-mentioned infection/infestation as a possible result.

Instructions and Guidelines:
To prepare solution, add 1.0 ml (~20 drops) of MediCoral per 1 US-gallon (3.785 L) of seasoned aquarium saltwater in a clean plastic or glass container, then immerse coral completely as follows: Small-polyp Stony Corals: 7 - 10 minutes; Large-polyp Stony Corals: 6 - 9 minutes; Soft (“Leather”) Corals: 8 - 11 minutes; Colonial and Solitary Polyps: 5 - 8 minutes. Discard solution when finished, then rinse coral in clean aquarium water and place coral into aquarium system. Process may be repeated daily as desired/required. If coral shows signs of irritation from being immersed, remove from solution; subsequently, coral may be placed into solution for less time, or strength of solution may be diluted. Solution may be increased in strength if hobbyist feels that there is reason to do so; do not exceed 150% recommended strength of solution (e.g. 30 drops per 1 US-gallon of water). It is suggested that new coral acquisitions be temporarily located in such a manner that the tissue around their base (where the soft tissue gives way to the bare skeleton) may be visually inspected for the first 1 - 2 weeks of ownership; doing so will enable the tissue to be monitored for signs of degradation and/or undesirable organisms (e.g. “stowaways”) that may have escaped detection during initial inspection. Failing to inspect new coral additions for signs of tissue degradation and/or infection as they arrive from outside sources can have a disastrous impact on an entire reef system.

I wish I can post pictures in here coz its amazing how much critters I got off on such small piece of coral. I am very happy with this product and highly recommend.

Good and bad

I am using this to dip corals which seem stressed or new frags I am bringing in. However, I see this product doesn't kill them but stun them. I've noticed some pests still hang on to the frag even after following directions. Although a good measure, it is not bulletproof. QUARANTINE.

Works Great

Before I started using this I was not using any iodine dip so I really cannot compare it to others, however since I have started using it after fragging I have not lost a coral yet! Highly recommended and necessary in my opinion.

I use this everytime I add some new coral to the tank. I just dont want to risk adding pests to the tank. This seems to do a good job at keeping pests out that may be hitch hiking with the coral. Great price. Much less than my LFS.

Day 4...

I got this stuff just in time, had some corals that went through a rough week with poor water(really bad batch of salt). First two days nothing really happened, but on day three I started seeing things stabilize. Im on day four of treatment, and of the 6 frags that were goners, 4 are sure to recover, and the other two are improving but not out of the woods yet. Overall it was a multi pronged attack, I did immediate water changes, dosed to get all my parameters to absolute perfect, and began daily dips. So while its not entirely this stuff, I do believe I got my moneys worth. And for the price, it doesn't hurt to have it in your arsenal.

Works as advertised

Seems to be an effective product for treatment of corals before you place them in your tank (like an iodine dip) or if they get damaged. Have used for the past month and have no complaints!
