TetraWeekend and TetraVacation are tropical slow release feeder blocks.
Existing plaster blocks are "old school" technology that can wreak havoc on your water quality!
Tetra's innovative new gel feeder blocks contain no plaster and feed from five days with the 24g Tetra Weekend, or up to 14 days with the Tetra Vacation 30g.
SIZE: TetraWeekend 24g (5 days)
