10 PLANTED TANK MYTHS
by George Farmer
Do you believe all that advice that everyone wants to throw at you regarding planted aquariums? Be baffled no more, as George Farmer happily separates the fact from the fiction.
1. Plants require soft water
Every plant I’ve owned I’ve successfully grown in hard water, including some of the hobby’s most demanding species.
Some, such as Vallisneria, thrive in hard water as they utilise the bi-carbonates. Those with very soft water may need to supplement magnesium, calcium and potassium levels in addition to their regular fertilisers. Some with extremely hard water have found it hard to grow certain species and require more CO2.
However, I have known aquascapers in London, having some of the UK’s hardest water, enjoy success with any plant they wish to grow.
Softer water is recommended for certain fish, especially for breeding, but if growing plants with bread and butter fish there should be no need to soften water.
2. Planted tanks will do best with heater cables
I have run more than 30 planted tanks without heater cables, many long term, and many aquascapers and planted aquarium hobbyists no longer consider them effective.
Heater cables can be relatively expensive and in some situations are not recommended. One manufacturer of a complete soil-based product now feels they can result in the leeching of excess nutrients into the water.
It’s better and less expensive to rely on healthy root growth to provide sufficient production of oxygen, prevent excess anaerobic bacteria and the foul-smelling hydrogen sulphide.
Invest in a better filter, CO2 system or quality substrate, as these will prove more beneficial.
