Dosage :- Standard: 1ml per 10 Litres per Week High Energy (CO2 injected): 3ml per 10 Litres per Week Notes * Nitrate in the levels used for a planted tank are fine when dosed separately to the Nitrogen cycle - i.e. your filter process. ** Phosphate does not cause algae – Sick plants from a lack of adequate nutrition does. FAQ Q: I read that Copper is harmful to Shrimps and Inverts. A: In high doses it can be, however in low doses it's essential for plants and inverts alike – copper is to invert blood as iron is to humans. - This is a safe dose. Review: Works really well. - I’ve been using this plant fertilizer for a few years now. I’ve bought at least 9 liters so far, and it works really well with 8-10 hours of light per day and a water change every two weeks.

I’ve bought at least 9 liters so far, and it works really well with 8-10 hours of light per day and a water change every two weeks. It’s very good, my only downside is that it’s a bit expensive and used to be cheaper.

It seems to keep my plants looking really healthy with good growth. Only need to use one a week, ### ⭐⭐⭐⭐ Complete fertiliser *by L***L on 27 December 2025* Quite a good complete fertiliser. The only issue is with the big bottle which developed mould before I could finish it hence I bought a smaller bottle which isn't cost effective but still gets the job done. ## Frequently Bought Together - TNC Complete - Liquid Aquarium Plant Food/Aquatic fertiliser (500ml) - API ROOT TABS Freshwater Aquarium Plant Fertilizer 13 g 10-Count Box - API CO2 Booster Freshwater Aquarium Plant Treatment 473 ml Bottle --- ## 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/49314082-complete-liquid-aquarium-plant-food-aquatic-fertiliser-500ml](https://www.desertcart.hr/products/49314082-complete-liquid-aquarium-plant-food-aquatic-fertiliser-500ml) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-05*
