Plants are made up of almost 50% carbon, which means CO2(carbon dioxide) is the most important plant nutrient of all. Aquarium water almost always contains too little CO2. Slow-growing, undemanding plants can manage without the addition of extra CO2, but, fast-growing and demanding plants require additional CO2 fertilization in order to grow healthy and strong. With the Nano CO2 Complete Set, Dennerle provides the appropriate CO2 system for mini aquariums, especially for lush underwater landscapes.

The Dennerle Disposable CO2 System is a convenient method of supplying your aquarium with CO2 in a practical disposable cylinder. This is ideal whenever repleneshing CO2 cylinders would be difficult or if the nearest CO2 filling service is too far.

The included CO2 tank will give an uninterrupted supply of CO2 fertilization.

The disposable cylinders are almost 100% recyclable as they are made almost entirely of metal, so may be thrown into the recycling bin when used up. So you can feel better about using them as an alternative to refillable CO2 cylinders environment.

Dennerle`s Perfect Plant System (included in the kit) has three different types of fertilizer: two basic formulas and one supplemental formula. The V30 Complete fertilizer and E15 FerActive fertilizer should be used every four weeks, and S7 VitaMix should be dispensed every week. To make dosing V30 and S7 simpler, check out the Dosater Automatic Doser.

The Perfect Plant Fertilization Fystem

Basic fertilizers E15 Iron and V30 Complete are comprised of vital substances which can endure in a tank for extended periods. Nutrients which cannot be built up and which are expended promptly are included in S7 Vitamix. Accordingly, S7 should be used on a weekly schedule.

V30 Complete

V30 Complete makes up nutrient deficiencies in a targeted manner, boosts the plants from the inside out, and encourages quick growth. A 50ml container of V30 is included in this box.

E15 FerActiv Iron

E15 FerActiv iron fertilizer makes sure that leaves have an attractive, fresh green hue by offering them divalent nutrient iron (or “white” iron). 20 tablets are included with this bundle.

S7 VitaMix

The vitamin complex concentrate VitaMix offers your plants all the vitamins and other vital substances necessary in the short term. A 50ml bottle of S7 is included with this kit.
