Why does plantedtank not bubbleing anymore

The amount of light and CO2 injection volume influence the photosynthesis of aquatic plants. Photosynthesis is not generated if either one of them is insufficient. The amount of light is not a big issue because everyone can get equally adequate amounts of light just by installing a lighting system that is appropriate for the aquarium tank size. On the other hand, the CO2 injection volume needs to be adjusted according to the type and volume of aquatic plants in the aquarium. In view of these facts, lack of CO2 is considered to be the cause of this problem. To solve this, install a Drop Checker, which indicates if the CO2 injection volume is adequate or not by color change, in order to adjust the CO2 injection volume to the adequate level. For your reference, the CO2 injection volume is considered adequate if the pH indicator turns a color indicating acidic (0.2 to 0.4) a while after the CO2 is injected.

When is the right time to dose

Add enough liquid fertilizer for one day every morning when the aquarium light is on.
Aquatic plants sometimes do not look well particularly when the water temperature rises in summer. In such a condition, aquatic plants become sluggish just like humans suffering from the summer heat. In this case, a little more potassium, for example, a double dosage of Brighty K should be added to increase the activity level of aquatic plants. In addition, adding supplements such as Green Gain containing botanical hormones is effective when aquatic plants do not grow well.

The Importance of water circulation and suface agitation in your plantedtank setup

It is of great importance to create sufficient water circulation and surface agitation in a planted Ecosystem.

Circulation will evenly distribute nutrients making them available for plants and bacteria. Aim for a circulation between 5-8 x of the tank volume per hour depending on plants grown and fish kept. Some prefer stronger currents while others weaker ones. Some aquatic gardeners use circulation of up to 10 x the tank volume per hour but they do reduce the water flow by using very long submerged spray bars which should be placed just below the surface.

Surface Agitation will insure sufficient gas exchange and will prevent the surface film from forming. Even though plants willd extra O2 via the surface agitation.
One should bear in mind that Oxygen is one of the most important electron acceptors involved in animal and bacterial metabolism provide lots of O2 through photosynthesis especially in CO2 injected systems it can’t hurt to ad.

The Importance of Maro and Micronutrients

The Natural Planted aquarium style of aquatic gardening tends to be less occupied with how plants are arranged and without more than the bare minimum in lighting, substrate and dosing aquarium water. While there is something to be said about the elegance of growing a planted tank with little to no effort, if growing the most robust and lush looking plants possible is your aim then you will want to get to know the importance of macro and micronutrients for plant growth. The Macro Nutrients that are most important for day to day plant growth are Carbon Dioxide, Nitrogen, Potassium and Phosphorus (or CO2 and NPK for short).

Nature Habitat Liquid Fertilizer

Nature Habitat Trace ( Brown Fluid ) is a trace element mix of iron, cobalt, chromium, copper, iodine, manganese, zinc and molybdenum. Nature Habitat Macro (Clear Fluid ) are all of the above but with added N and P – Nitrogen and Phosphate. When plants show signs of micro nutrient deficiencies you will see that the plant may look as if it is growing as normal, but the new growth is pale or white. This is due to the fact that plants can only obtain micro nutrients from the substrate or water column as it grows, where as if the plant is showing signs of macro (N, P, K - Nitrogen, Phosphates, Potassium) deficiencies, you may see the plant show signs of stunted growth, deformed leaves, and premature die off, pin holes in the leaves or signs of brittle leaf structure. Plants have the ability to obtain macro nutrients from other parts of themselves. Plants will store macros in leaves, bladders or bulbs under the substrate as part of its root system, so when plants are running low on macros it may be a sign of long term deficiencies.
