Pests like AEFW, red flatworms, and pest nudibranchs are catastrophic in established reef tanks and are nearly impossible to eradicate without full quarantine. A 5-minute Reef-Primer dip catches the vast majority of hitchhikers.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow many dips do I get from a 180g container?\u003c\/strong\u003e\u003cbr\u003e\nAbout 4 dips at the standard 45g per 1 US gallon dose. Larger frags or extended quarantine procedures (multiple dips per frag at 5-day intervals) will use more. If you only need one dip, the single-use \u003ca href=\"https:\/\/squeakysaquatics.com\/products\/polyplab-reef-primer-shot-coral-dip-45g\"\u003eReef Primer Shot 45g\u003c\/a\u003e is more economical.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWill it hurt my coral?\u003c\/strong\u003e\u003cbr\u003e\nNo, not when used correctly. PolypLab specifically formulated Reef-Primer for low-stress coral dipping — it's safe on LPS, SPS, soft corals, zoanthids, mushrooms, and even anemones. Don't exceed 5 minutes; visibly stressed or already-bleached corals should get the shorter end of the dip time.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes it kill AEFW eggs?\u003c\/strong\u003e\u003cbr\u003e\nNo — AEFW egg stages survive any coral dip currently on the market, including Reef-Primer, CoralRX, and Bayer. To eradicate AEFW, run incoming Acropora through quarantine with repeat dips every 5 days for at least 3 cycles to catch newly-hatched flatworms before they reproduce.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow does it compare to CoralRX, ReVive, or Bayer?\u003c\/strong\u003e\u003cbr\u003e\nReef-Primer is the gentlest of the four — potassium-based instead of iodine (CoralRX, ReVive) or pesticide (Bayer). It works well on a wide range of pests but is less aggressive on tough cases like red bugs (use Interceptor instead). For everyday quarantine of new frags, Reef-Primer is an excellent low-risk choice; Bayer is reserved for known infestations.\u003c\/p\u003e","brand":"PolypLab","offers":[{"title":"Default Title","offer_id":48583804387547,"sku":"P-00012","price":44.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0767\/5209\/3403\/files\/PL30187-2.png?v=1775821503","url":"https:\/\/squeakysaquatics.com\/products\/polyplab-reef-primer-coral-dip-180g-saltwater-reef","provider":"Squeaky's Aquatics","version":"1.0","type":"link"}
