Most 29 gallons are 30" x 12", which is a total of 360 square inches. Divide that by the recommended 30 square inches per tablet and you will need to use 12 tablets for the aquarium, once per month. Of course, that's providing your aquarium is 30" x 12". **Q: i have a 20 gallon tank, can i use theese with the liquid c02 booster and leaf zone or flourish excel?? or will i be adding to much.** A: I use them with leaf zone and flourish Excel... no problem so far...I do not treat the whole tank with this tabs... I only add them to specific plants that need more nutrients such as my aponogetons ( bulbs) **Q: I need use how many tablets for 30 gl?** A: I put all 10 inside a 60 gal. I guess just put 5 for the 30 gal. ## Frequently Bought Together - API ROOT TABS Freshwater Aquarium Plant Fertilizer 0.4-Ounce 10-Count Box - 4Pcs Aquascaping Tools, Jeimier Aquascape Kit, Long and Strong Aquarium Tweezers, Scissors, Algae Scraper, Aquarium Plant Tools, Fish Tank Plant Trimming Kit - API LEAF ZONE Freshwater Aquarium Plant Fertilizer 8-Ounce 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/6666690-root-tabs-freshwater-aquarium-plant-fertilizer-0-4-ounce-10](https://www.desertcart.hr/products/6666690-root-tabs-freshwater-aquarium-plant-fertilizer-0-4-ounce-10) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-21*
