For 18+ years, I have been wrongly using cheap Tilapia and Catfish food sourced from Tractor Supply mixed with large-sized dry non-oily dog food additionally mixed with Koi Food. I would mix all this up in a large metal trash bin with a lid. My water has always been an issue. That crap dog, catfish, and tilapia food really was meshing my water up. I didn't want to spend the money on high-dollar Koi food seeing that I have sooooo many fish that would consume so much. Well, my water as of today is crystal clear and healthy, and I am now feeding the fish this awesome brand of Sera Koi food. I figure it will cost me at least one bag a week. But I have conceded that the cost is worth it. This Sera Koi food is TOP NOTCH stuff. I can't imagine seeing it negatively impacting my water like the stuff I have been putting in it has. I highly recommend this product. I see NO oils in the water when I put it. I feel like this product is a real winner. And the size is a good 1/4" in diameter. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Koi love it *by G***T on Reviewed in the United States 🇺🇸 on June 26, 2023* I have weird fish that are very picky with what they eat and they absolutely love this food finally eating it with gusto it's so nice to see ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Arrived on time *by H***N on Reviewed in the United States 🇺🇸 on September 11, 2020* I have a pond in my yard and my koi fish really like this food ## Frequently Bought Together - sera KOI Professional Summer Food, 2.200 g - sera KOI Professional Spring/Autumn Food, 2.200 g - Tetra Koi Pond Fish Food Sticks 1.5kg - biologically balanced for koi fish --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/43160213-sera-koi-professional-summer-4-85lb-energizing-for-warm-seasons](https://www.desertcart.hr/products/43160213-sera-koi-professional-summer-4-85lb-energizing-for-warm-seasons) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-04-25*
