The effects of choosing a bad substrate are not as obvious as bad Co2, lighting or heating choices for your plants, but the long-term effects can be devastating. Changing a substrate in an established aquarium is one of the hardest procedures you can undertake.

Substrate is a source of nutrients for your plants and secondly serves to hold whichever plants you would like to keep in place. At the very least you will want to choose a substrate which is rich in the macronutrients that your aquarium will need. A deficiency of macronutrients results in many unwanted physical effects in your plants, ranging from discolouration and dis figuration, to browning and death. Needless to say, it is important that your plants have all the nutrients that they require. Although it is possible to supplement some of them via fertilizers, this can introduce water chemistry issues of its own.
When choosing a substrate, try to establish what macronutrients that it contains. It is helpful to make sure that your chosen substrate is intended for your kind of aquarium. If you were to choose a substrate that was designed for salt water aquarium use, you run the risk of releasing unwanted slats or minerals into the water. In the case of crushed coral, this may raise the pH of the water to an unwanted level and the potential knock-on affects of this can be deadly.
One of the best ways to work out what would be good for your aquarium is by locating the hobbyists themselves. Forums are often priceless in helping you find exactly the right combination of materials to make your own substrate. You will also find recommendations for commercially available substrate for your aquarium, be it tropical, freshwater, marine or salt. It is always worth taking forum recommendations with a pinch of salt, unless a full overview of all the macronutrients and general use of the substrate is given. Some examples of good major brands of substrates would be Fluorite, Eco Complete and ADA Aquasoil. Before you buy anything, read the manufacturers packaging carefully.
When choosing your substrate, try to provide a substrate of three to eight millimetres per grain. Too much is as bad as too little; with too little the roots will be suffocated and with too much, there is not enough contact with the roots. You will need to do your research, with the kind of aquarium you keep in mind to find the best thing for your plants and fish.
With live aquarium plants you can overcome all the problems of a non-planted aquarium. You can improve the quality of your aeration, filtration, food and algae control. You can improve the lives of your fish.
