At the moment, my lonely Betta has been living in a heavily planted 40 gallon tank with some trumpet snails. I have been using only seachem products and they have not not affected him nor the snails, negatively. However use caution when dosing - follow directions. If tank isn’t heavily planted I would half the doses... **Q: Can I use flourish potassium on hibiscus plants?** A: Would work on any plants I would think. **Q: How many ml do i use for a 72 gal and a 75 gal tank?** A: 10 ml per 60 gal. 2 - 3 times a week per the instructions. **Q: Will it work on watermelons** A: This product is intended for aquarium use. I suppose it would work in a garden scenario, but is expensive by comparison to garden fertilizers (which are great for plants, but generally kill fish if you put them in an aquarium). ## Frequently Bought Together - Seachem Flourish Potassium 250ml - Seachem Flourish Nitrogen 250ml --- ## 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.ph/products/256598941-seachem-flourish-potassium-supplement-250-ml](https://www.desertcart.ph/products/256598941-seachem-flourish-potassium-supplement-250-ml) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-07-07*
