Important Information

Hydrocks will not kill or harm seahorses. It will not harm scaleless fish such as dragonets. In addition if you have invertebrates in the tank, such as red shrimp, this treatment will not harm them.  It will not cause any major changes in the bio-filter of your tank either. Hydroxs will accomplish the following:

It will kill hydroids in the carpeting form, branching form, in fact, so far all types of hydroids have been successfully destroyed with Hydoxs. Hydroxs will kill jellyfish larva, but the kill time on them is a little slower. It will also eliminate bristle worms. In most cases there will be some floating yellow debris on the top of the water, but you have NO need to worry about this. If a fish eats it, it will not harm them in any way. Hydroxs is a proprietary product that belongs to FishNth, and is currently in the patent process.

When using Hydroxs the results are as follows: At first the hydroids will not appear to have been affected at all. Please do not let this worry you. The product is working and you will start to see the hydroids die or just disappear by day 4. By day 6 you should change the water in the tank to remove all the rest of the dead hydroids and or jellyfish. Any hydroids or jellyfish larva that remain visible will tend to be white or clear in color. Do not let this concern you, as they are dead and will scrub or brush off any surface easily.

In rare cases treatment aggravated a few turbo snails and crabs. Most were not upset with the treatment. Keep in mind if you remove the snails or crabs, you will run the risk of re-infecting your tank if they are not treated and have hydroids in their shells, or possibly in their digestive track(s). I recommend leaving snails and crabs in the tank for the treatment unless they become stressed. If your snails or crabs become stressed, follow the treatment for Gorgonias, written below.

Gorgonias, or corals should be treated for 30 minutes, them removed. They can be added back to the tank for another 30 min at the end of treatment. I recommend buckets or tanks of clean water for them during this time, and extra water changes for those "holding" tanks are advantageous during this time. The gorgonias are not harmed by this much of the Hydroxs treatment. Most corals will only need the last 30 min of the treatment. To date, because Hydroxs is able to kill stinging hydoids, it has an adverse effect on corals.

Below is a special note for those raising fry with extremely high densities of hydroids present! This only pertains to fry rearing only tanks that are super saturated with hydroids. In tanks that are saturated with hydroids the stinging cells will overwhelm young seahorses if they are not relocated to another tank. They still need treatment, but you will not loose fry from the treatment if you relocate them. In these cases, the seahorse fry are taken to a separate non-infested tank. When you move the fry to the new tank that will infest the new tank with microscopic hydroids. However, it will eliminate their immediate exposure to adult hydroids and their stinging cells. The tank the fry were removed from, their "home tank" as well as the temporary fry tank can now be treated. The exception to this procedure is H. zosterae, and H. erectus. Their fry can be treated in the tank with the adults except in cases of heavy infestations. In cases of a heavier infestation that was realized, the amount of stinging cells released when the tank is treated will cause the seahorses to thrash and try to leave the tank. In those cases you will need to relocate the young as stated above. To date there have only been 3 cases where this was necessary. All other tanks were treated with out relocating the seahorses, be they adult or young seahorse fry.

Treatment instructions will be sent to you by e-mail for your specific tank.

Remember to remove carbon or any Poly Filter Pad before you treat the tank.

If for any reason Hydroxs does not rid you of your hydroids, please contact us for assistance.
