Customer Reviews (5.0 / 5 · 4 reviews)

Eva ★★★★★

These tablets dissolved quickly in the tank water, and my betta’s fin rot cleared up noticeably within three days. The 30-count bottle is plenty for multiple treatments without needing a prescription.

Lucy ★★★★★

Dealt with a nasty case of columnaris in my 40-gallon tank and this cleared it up within about five days. The 500 mg tablets dissolve easily in the water, which made dosing way less of a hassle than I expected.

Eli E. ★★★★★

Noticed my guppies' clamped fins cleared up within about four days of dosing the tank. The 500 mg tablets dissolve easily and the 30-count bottle lasted through the full treatment plus a spare round.
