Flatworm eXit Aquarium Treatment, 10ml/300 Gallons

Salifert Flatworm eXit is an aquarium water treatment sold in a 10 ml bottle, and that 10 ml doses 300 gallons of tank water. It begins to act within thirty minutes of being added. The dose is intended for a single tank of up to 300 gallons, and the manufacturer asks for several steps before and after the treatment because of the flatworm's toxic body juice.

What reviewers say about using Flatworm eXit

Some reviewers report that the treatment works quickly once it goes into the tank. Others mention risk to other tank inhabitants, and a third group notes that carbon and water for a change need to be on hand.

How the 10 ml bottle and its coverage work

• One bottle holds 10 ml, and that volume covers 300 gallons.
• The manufacturer states that the product starts to work in thirty minutes.
• The dose is placed in the tank's high flow zone.
• Flatworms are flushed out of hiding places with a power head or another device before the dose is added.
• Before treating, as many flatworms as possible are siphoned out.
• After the dose, dead flatworms are siphoned out again, and roughly 1 pound of fresh high quality carbon per 50 gallons is added to take up remaining toxic juices.
• Water for a 25% change should be ready in case it is needed.

Checks before you treat a tank

This treatment suits a tank of up to 300 gallons, and a single 10 ml bottle covers that volume. Tank owners with a larger system need to account for the extra water beyond 300 gallons, since one bottle is dosed for 300 gallons.

Extreme care is required during use, the manufacturer warns, owing to the toxic body juice of the flatworm. Should that juice go unchecked in the aquarium, aquatic inhabitants will likely be lost. The routine therefore calls for siphoning before and after the dose, carbon at about 1 pound per 50 gallons after siphoning, and a 25% water change ready to go if required.

Questions buyers ask about Flatworm eXit

How much water does one bottle treat?

One 10 ml bottle treats 300 gallons. The whole dose is aimed at a tank of that size.

How long before the treatment starts to work?

The manufacturer states that it starts to work in thirty minutes. That is the stated time from adding the dose.

Where in the tank is the dose added?

The dose goes into the tank's high flow zone. Flatworms are first flushed out of hiding with a power head or another device.

What has to be done before the dose goes in?

As many flatworms as possible are siphoned out before treating, and hiding places are flushed with a power head or other device. Both steps come before the dose.

How much carbon is needed after treatment?

About 1 pound of fresh high quality carbon for every 50 gallons is added after siphoning the dead flatworms. The carbon is there to take up remaining toxic juices.

What water change should be ready?

Water for a 25% water change should be ready in case it is required. The manufacturer lists the change as a precaution, not a fixed step.

The order of steps for a treatment

The manufacturer's sequence starts before the bottle is opened: flush the flatworms from their hiding places with a power head or another device, then siphon out as many as you can. Add the product to the high flow zone of the tank, and after that siphon out as many dead flatworms as possible. Once siphoning is done, add roughly 1 pound of fresh high quality carbon per 50 gallons to remove remaining toxic juices. Keep water ready for a 25% change if one turns out to be required.

What customers say

Customers report that the treatment works quickly and effectively at getting rid of flatworms. However, the worm destruction aspect receives mixed feedback - while some customers say it killed all their flatworms, others report it didn't eliminate all of them. Moreover, safety concerns are raised, with some customers noting it doesn't harm inverts while others consider it dangerous. Value for money is also mixed, with several customers warning not to waste money on it.
