If you already understand the difference between macro and micronutrients and want the underlying chemistry, including what NPK does, how to read a deficiency symptom, and how to structure a weekly dosing routine, our Planted Tank Fertilizer Guide: Macro vs Micro Nutrients & Dosing covers that in depth. This guide starts from the opposite direction: you know you need to fertilize, and you’re standing in front of four or five different brands trying to work out which one to actually put in your cart. Here’s how Aquavascular, Easy Life, Seachem Flourish, and Tropica differ in practice, with real stock currently at IndieFur.
Aquavascular: a full modular range
Aquavascular is built as a complete, mix-and-match dosing system rather than one or two flagship bottles. Aquavascular Macro Elements and Aquavascular Micro Elements dose the two core nutrient groups independently, which suits CO2-injected tanks where you want separate control over each. For hobbyists who’d rather dose one bottle, Aquavascular Complete Nutrition combines both into an all-in-one. The range goes further than most competitors on hardness support too: Aquavascular KH Booster and GH Booster (Cal Mag) restore carbonate and general hardness independently of NPK dosing, and Aquavascular Kalrich and Ferropure isolate potassium and iron for hobbyists chasing a specific deficiency rather than a broad-spectrum top-up. For carpeting plants and heavy CO2 setups specifically, Aquavascular PGR1 and PGR2 are formulated as a two-part growth regime.
This range is the best fit for hobbyists who want granular, element-by-element control and don’t mind managing several bottles.
Easy Life: two distinct product families
Easy Life splits its planted-tank range into two purposes that are easy to confuse by name alone. The GreenScape NPK + Micro Fertilizer (available in 250ml and 100ml as well) is a genuine all-in-one, covering macro and micronutrients in one bottle for straightforward weekly dosing. The RedScape Aquascaping Fertilizer line (also in 500ml, 250ml, and 100ml) is positioned specifically for red-leaved stem plants, which need proportionally more iron and trace elements to hold their coloration than green plants do.
Beyond the two headline fertilizers, Easy Life’s supporting range covers carbon and problem-specific dosing: Easy Life EasyCarbo Bio and standard Easy Carbo supply a liquid carbon source for tanks without pressurized CO2, Easy Life Profito and Ferro round out trace and iron dosing, and Easy Life AlgExit targets algae outbreaks that sometimes follow an over-fertilized tank rather than an under-fertilized one.
This range suits hobbyists who want one clearly-labeled bottle per goal (general growth vs. red coloration) rather than assembling a system from separate elements.
Seachem Flourish: buy the base, add what’s missing
Seachem’s approach is a base fertilizer plus a-la-carte additions. Seachem Flourish is the foundational all-in-one, covering a broad range of trace elements for general planted tank health. From there, Flourish Iron, Flourish Nitrogen, Flourish Potassium, Flourish Phosphorus, and Flourish Trace let you supplement a single nutrient once you’ve identified a specific deficiency, the same principle behind Aquavascular’s element-by-element bottles, but built around a Flourish base rather than a standalone macro/micro split. Seachem Flourish Excel is Seachem’s liquid carbon source, directly comparable to Easy Life’s EasyCarbo, and Flourish Advance is a newer growth stimulant aimed at root and overall plant development.
Seachem Flourish is the natural pick for hobbyists already using other Seachem products (Prime, Stability) who’d rather standardize on one brand across water conditioning and fertilizing.
Tropica and ISTA: low-maintenance options
For hobbyists who don’t want to manage a weekly liquid dosing schedule at all, Tropica Nutrition Capsules are pre-measured root-tab capsules pushed into the substrate near root-feeding plants, delivering a slow-release dose without any liquid measuring. ISTA Water Plant Trace Elements (120ml, also in 250ml) is a straightforward trace element top-up that pairs well with any of the all-in-one fertilizers above if you’re seeing early micronutrient deficiency signs between doses.
CO2 support without pressurized injection
If you’re not running a pressurized CO2 system, API CO2 Booster and API Leaf Zone offer a lower-cost entry point than a full liquid carbon line, though EasyCarbo and Flourish Excel above are generally considered more concentrated options for the same purpose.

Making the call
If this is your first planted tank, pick one all-in-one (GreenScape, Complete Nutrition, or base Flourish) and dose it consistently for a month before adding anything else; a single well-dosed all-in-one outperforms three mismatched single-nutrient bottles used inconsistently. Once you’re running CO2 and pushing faster growth, that’s when it’s worth switching to element-by-element dosing (Aquavascular’s individual bottles or Flourish’s single-nutrient line) so you can correct a specific deficiency without over-dosing everything else. For the deficiency symptoms themselves and a suggested weekly schedule, our Planted Tank Fertilizer Guide walks through both in detail.
