OUR PRODUCTS

GT aqua VitaPlant

General fertilizer intended for aquatic plants. Provides water with all the essential nutrients needed for healthy plant growth. It adds macroelements into the water, such as potassium and magnesium, which are usually absent in tap water. It provides microelements such as iron, manganese, zinc, boron, copper, molybdenum, nickel, cobalt necessary for the proper growth of plants. It does not contain nitrogen and phosphorus compounds, which, although very necessary for plants, may cause the growth of algae in the aquarium. In typical aquariums, these ingredients most often come from fish feces and uneaten food remains in sufficient quantities.

Dosage:

5 presses of the dispenser (or 7 ml) for 50 liters of water once a week after water replacement.

Available sizes: 200 ml, 500ml, 5000 ml.

GT aqua VitaFish

FAQ

Are GT aqua fertilisers safe for fish, shrimps and snails?

Yes, GT aqua fertilisers are utterly safe for all aquarium animals provided you follow dosing guidelines specified by the manufacturer

Can GT aqua fertilisers be used together with fertilisers/preparations of other brands?

Yes, you can combine GT aqua products with other equivalents. However it is advisable to make sure the fertiliser line comes from one manufacturer. You can then be sure that all ingredients provided to the aquarium are used in well-balanced quantities.

I want to change my current fertilisers into GT aqua ones, how to do it safely?

If you wish to change fertilisers into GT aqua equivalents, please be advised to make major water changes 2-3 times a week before changing products. The point is to remove ingredients from the column of water and start a new fertilisation plan with GT aqua products. You have to remember that plants need some time to adapt to new conditions and availability of ingredients, and the temporary period may take from 2 to 3 weeks. It is of lesser importance if you fertilise with separate ingredients, such as N, P, K. In such a case you can just keep on implementing your fertilisation plan. Neutralisation of the column of water is significant in the case of fertilisers composed of several ingredients, e.g. micro-elements or macro-elements in one bottle (the so-called All-in-One fertilisers).

My plants are weak, when can I expect to see results of using GT aqua fertilisers?

If your plants suffer from nutrients deficiency, early results should come after a couple of days. Remember to provide plants with a suitable amount of light and permanent access to CO2.

My plants are weak. I have used GT aqua fertilisers but their condition has not improved. Are these fertilisers reliable?

If your plants have suffered from lack of nutrients, remember that degraded leaves cannot revive any more. Plant leaves are unable to regenerate so you need to wait for growth of new and healthy plants.

My plants have revived but their lower leaves are not nice, what to do?

This being the case, we suggest that you grow as many healthy plants as possible. When trimming, cut healthy plants off and put them into the water bowl. Next cut degraded stems off as close to the bottom as possible. Replace removed plants with new healthy plants and watch them grow.

I use macro-element fertilisers but I can still notice some deficiency on lower leaves, should I increase dosing?

If you dose 10-15ppm of NO3; 1-1,5ppm of PO4 and 20-30ppm of potassium per week, your plants surely do not suffer from shortage of nutrients. The problem may be too dense plants which prevent lower parts of the plant from accessing light. If the problem is related to the aforesaid density, you may also experience water circulation and carbon dioxide distribution issues.

I supply the aquarium with additional iron but my plants are still pale, what is wrong?

Plant discolouration may be directly related to emergence of colouring in their tissues. You need to meet a series of conditions to make sure plants can produce them. Iron is one of them but iron itself is not enough. The plant must be provided with an access to increased amount of magnesium, and the aquarium must be illuminated with a strong light of a suitable colour. Importantly surplus of nitric compounds will result in beautiful green colours, while red plants will turn orange. If you wish to discolour red species of plants, you have to keep a low content of nitrates in the reservoir, max. about 5 ppm.

If I use GT aqua fertilisers, do I have to measure water parameters through aquaristic tests?

Yes and no. I advise you to test water from time to time. With time you will see how your reservoir reacts to fertilisation and will be able to determine irregularities. However plants signal deficiency or surplus of ingredients in a very similar way and to make sure what is missing, you need to test water. But please do not rely on test results only. Aquaristic tests are burdened with errors and only present you with the general volume of the specific ingredient in water, rather than its precise value. For example, NO3 test scale is calibrated to 10ppm, so the 5 and 15 value test will probably show 10, and this makes a clear difference when you plan fertilisation of plants.

After trimming plants, should I fertilise my aquarium in the same way as before?

No, major plant trimming causes the plant weight to drop dramatically, and so does a need for nutrients. After trimming, we advise you to slightly increase nitrogen and potassium supply in order to stimulate plants to grow, and reduce amounts of phosphorus and micro-elements. Once new growth cones have emerged, you ought to add bigger doses of phosphorus and micro-elements. When plant weight is satisfying, you can lower nitrogen supply to make sure the growth pace is lower and red plant discolouration more intensive.

I have an active-substrate aquarium, I use GT aqua Booster P (phosphorus) but tests still show 0ppm of PO4 in the column of water. Should I increase fertilising to level the nitrogen and potassium relation?

Definitely not! The active substrate is able to absorb phosphates from the column of water and accumulate this ingredient. Stick to your regular fertilisation until you can see shortages of this ingredient. Active substrate is a great source of nutrients for plants but fertilisation requires you, as an aquarist, to adopt a slightly different approach. If any of the elements is unavailable in the column of water, it does not mean that the plant has no access. Soil-type substrates serve as some kind of fertiliser reserve for plants through roots. Make sure potassium is always available in the column of water.

How to select fertiliser doses for my aquarium throughout the week?

Take water parameters, e.g. NO3, PO4, K, Fe, after you change water. Supply fertilisers to the aquarium everyday, according to your schedules. Retake parameters before the change and see which elements in water accumulate, which are gone, and which remain unchanged. This is crucial for adjusting the fertilisation schedule. Retake this sequence a couple of times to be able to adapt fertilisation to your own aquarium. Remember that emergence of algae in the reservoir is a sign of excessive concentration of elements in water.

What water parameters are the most favourable for plant growing?

It is very difficult to give a specific answer to such a question. Looking for perfect water parameters which meet requirements of all plants is like searching for the Holy Grail. Water quality requirements vary, depending on specific plant species. A vast majority of plants is grown in water of the following parameters:

Ca 20-35ppm

Mg 5-15ppm

K 10-25ppm

Most plants favour soft water with as low temporary hardness as possible. Keep the aforesaid hardness low (1-3 dKH) to see plants beautifully grow.

Are aquariums kept by GT aqua based on active substrates or gravel?

Aquariums in our company are based on both. However we definitely advise you to choose active substrates as a rich source of nutrients for plants.

What kind of fertilisation is used by GT aqua in its tanks?

It is very hard to give a straight answer. Every aquarium is different, with specific illumination, with specific dosing and CO2 distribution system, with specific number of fish and specific species of plants, ending up with specific water parameters. Fertilisation schedule must be chosen on a case-by-case basis, for your own aquarium, based on your experience. Assuming our reservoir is based on the active substrate and provided with a very big amount of high-quality light, we dose carbon dioxide and make sure its high content is permanent and use water from RO filter, and the number of fish is moderate:

 – we mineralise water through GT aqua Booster GH based on 1 ml per 1 litre of pure RO water, which gives about 30ppm of Ca and about 10 ppm of Mg

 – we keep potassium level at about 15-20ppm, sometimes 25ppm (potassium is replenished after changing water and minor daily doses of 0,5-1ppm are added with the use of GT aqua Booster K)

 – using GT aqua Booster N fertiliser, we add daily doses of NO3 in the amount of 0,5-1ppm so that the level in the column of water is close to 0ppm. After trimming, we slightly raise dosing

 – based on GT aqua Booster P fertiliser, we supplement phosphorus, add about 0,1 up to 0,35 ppm per day, depending on the species of our plants

 – we supply micro-elements in our reservoirs with special regard to plant observation, usually we use GT aqua Booster Trace in the amount of 1-2 ml a day. We monitor aquarium glass and growth cones. If green spot algae emerge quickly, we reduce the fertiliser dosage or supply it every second or third day. If there are no green spot algae on the glass and growth cones are not healthy, we raise dosing but remain careful.

 – additionally we dose iron with the use of GT aqua Booster Fe every second day in the amount of 0,05ppm.
