Re: substrate for planting carpet plants

i prefer to use construction sand treated with acid for a day atleast because natural sand is alkaline in nature.also i heard that sand gets compact after a period of time but in my experience it didn't occur as the tenellus runners kept on boring through it.

the lowest layer is still a concern for me...i was hoping for vermicompost like you used but since it would require a maturing time of around 4-5 months..i pass that option..any other fertile option to mix with lat?

Keep the flow low. Too much flow will uproot any plant let alone hairgrass. In planted tank, we need mild flow not water current.

Don't use too fine sand. They will get compact and root growth will hamper. ADA AS is 4-6mm of size and hairgrass/ HC/ Glosso grows nice on it. Fine sand will not help you to keep the plants on substrate but it needs a good root system.

guys this is a basic question that comes in everyone's mind..why do we need to use a nutrient rich substrate when aquatic plants can absorb nutrients through water column..

there are different types of aquatic plants like stem plants, bulbs, rosette plants etc..stem plants can easily absorb nutrients from water column..but the others cant..they depend on the root system for the supply of nutrients..hence the high nutrient, high cec required..if you notice you will see that plants that grow really well, multiply fast,grows thick have a very good root system to support..most of the carpet plants have very good root system....hence nutrient rich substrates are needed..even i have seen in these years that the nutrient rich substrate plays a very important role in maintaining the stability of the water parameters..it helps in maintaining a steady nutrient quotient in the water which is absorbed by the stem plants and thus have a buffering effect to some extent.

so gecho what would the recipe be for a DIY substrate for planting carpets?

i believe lat+soil is the general thing, but what else would you recommend.

Laterite , soilrite etc have cec property but which substrate additive actually adds the nutrients Abhirup da? Could Humus or vermicompost be the choice?
