Frag Plugs - Mixed 50pk
An assorted fifty-pack of ceramic frag plugs means you're never stuck without the right colour mid-cut. The EcoTech Marine Frag Plugs – Mixed 50pk bag together black, natural and purple ceramic discs in one pack, useful for a swap-meet cutting session, a mixed customer order, or simply not caring which colour lands under the polyp once it's encrusted. Same pH-neutral, kiln-fired ceramic and the same scored, slotted base as every colour in the range – pick this pack when colour is a convenience, not a requirement.
Key features
- No colour sorting needed – a ready assortment of black, natural and purple plugs in one bag.
- Scored top surface – gives coral glue and epoxy putty a rough face to key into, so frags bond fast.
- Slotted base – sits directly into standard egg-crate (light diffuser grid) frag racks with no extra fittings.
- Kiln-fired, pH-neutral ceramic – won't shift tank chemistry the way some resin or cement plugs can.
- Bulk pack of 50 – covers most full-tank fragging sessions without reordering mid-job.

Common questions
What's the colour split in a Mixed bag?
EcoTech doesn't publish a fixed ratio – expect a rough mix of black, natural and purple rather than an even three-way split.
Can I request a specific colour ratio?
No – the Mixed pack ships as EcoTech packs it. Order the single-colour packs if you need a guaranteed colour.
Can I use these in a freshwater or planted tank?
No – frag plugs are made for coral fragging in marine and reef systems only.
