Does what it says!
This fert is really good and I've used it for a few years now with great results. The tank used to suffer from occasional green spot algae outbreaks, but they have completely disappeared since using this fertilizer. Highly recommended

The best fertiliser
I have been using seachem, tropica, and other brands. None was good at keeping N/P ratio in my 5 tanks. I had to add seachem N and P separately which was pain in the butter. I have been using this fertiliser for 5 days!!! And I have stable N/P ratio with only one fertiliser:)!!! N03- 40 ppm, PO43- at 0.5 ppm which in turn gives my plans power pearling :) and healthy growth. I don’t even have to use automatic doser. It is genuinely the best fertiliser for hitech planted tank. Full recommendations!!!!

Apt 3 fertiliser for tropical aquarium
Delivered on time, the company does state the dosage on the bottle, but how is one to measure the dosage, no pipette no stating what the cap holds, for such an expensive item you expect a measuring item

Seems good.
Comes with a pippette up to 3 ML. Nice packaging, ownly downside is that the instructions aren't on the bottle other then that looks like a good product.

Expensive but excellent
This product from my experience is the best all-in fertilizer and gives aquarium plants all that they need. Easy to dose, the results are apparent quite quickly (within 2 weeks) with the red plants being more red and the green ones more green. It is expensive compared to other products but if you only have a small aquarium (the one I use this for is a 30 litre cube) then the cost of using it is not really a factor. A 300 ml bottle will last almost a year.

Expensive but very good
I’ve used various liquid fertilisers over the years along with root tabs, I have a low tech gravel substrate 40 gallon aquarium with lots of plants and mainly nano size fish. This stuff works very well, I have good growth boost of my plants, certainly better than with other liquid ferts. It’s rather expensive though!

Used lots of other brands all of them worked but plants still died or struggled this is amazing and has lasted me ages

ソイルの栄養が明らかに切れてきていたので使ってみてます。 トリミング後はやはりソイルの栄養が残っていた頃に比べると新芽の展開・成長はゆっくりですが、それでもちゃんと成長してくれてるので効果はあるのだと思います。 まだ効果は曖昧ですが、頂芽の萎縮しやすい種の萎縮も見られないのでこれからも継続して使ってみたいと思います。 しっかり濾過サイクルが整った水槽で水草が多めの環境であればさほど苔も出ていません。

Ottimo prodotto, costoso ma un altro livello rispetto agli altri che ho provato! Consigliato

This is one of the best all-in-one fertilizers I’ve used. Easy to dose, and my plants are thriving with rich color and steady growth. Algae is under control, and I’ve seen noticeable improvement within a couple of weeks. Highly recommended for planted tanks!

Era algo escéptico a cambiar demarca de abonado y tener que echarlo todos los días como indica las instruciones a diferencia de otras marcas ,me daba palo la verdad , pero con los resultados que tiene es espectacular . En un acuario plantado de 60 litros con CO2 de botella he pasado de unas plantas más bien normalitas a una jungla en cuestión de semanas . Antes apenas podaba una vez cada 2 meses y pico, ahora como me despiste las plantas le quitan el sitio a los peces para nadar en dos semanas . Lo recomiendo 100%
