Description
Neutro Combo - Low Tech is an ALL IN ONE kit for the Low Tech (non CO2) aquarium. You make a little saving too!!
Neutro T is a liquid aquarium plant fertiliser which provides all the necessary trace elements including iron for your low tech planted aquarium. Low tech means aquariums which are not using pressurised CO2. The ingredients in Neutro T are special. They work quickly and effectively when dosed as recommended. Your plants will show the benefits of this product and reward you in no time.
Dosage: This product needs to be dosed daily so that your plants have a steady stream of nutrients. There's little point in dumping a weeks worth of fertilisers in one go. Simply add 5ml per 100L every day. It doesn't matter what time of the day you dose, as long as it's every 24 hours.
If you are using CO2, then you need to dose Neutro+ which contains trace elements and macronutrients (it's an all in one solution). So Neutro T for low tech planted aquariums and Neutro+ for high tech planted aquariums.
However, regardless of what type of planted aquarium you have, we recommend using Neutro CO2 which is a liquid carbon supplement (see related products for more information).
Bottle sizes: Small = 500ml, Medium = 1L, Large = 2L, XL = 4L
Neutro CO2 is a liquid source of carbon for the planted aquarium.
For those of you not familiar with it, carbon is essential for all healthy plant growth and can be provided via gas, or liquid. The liquid form is less potent than gas but still very effective. It won't make your plants pearl (this is when you see O2 bubbles coming from the plant) but it will help them grow. Plants that have access to liquid carbon will do far better than those without.
What happens when plants don't have access to carbon?
Tap water has zero carbon in it so if you're not adding any to the water you can safely assume you have no carbon at all. So if you're not dosing it, plants will not photosynthesize as they should. As a result, they stop growing (or show stunted growth) and can't compete with algae for nutrients and the downward spiral begins. If this carbon deficiency continues, plants inadvertently (out of their control) release sugars and other nutrients which attract algae and it's these sugars and nutrients they so desperately need, but just can't hang onto.
It's a bit like vomiting (sounds gross but true). Without carbon, plants lose energy, nutrients, health and well-being. Their colours disappear. The end result? Algae everywhere.
So you can see why it's actually very important to dose carbon and why we recommend that all plants receive a daily dose because, without it, they will always struggle.
So the sooner you dose liquid carbon the better.
Can I double dose if I have algae?
You can - for short periods but no more than double. It's important to understand that if you do have algae, your tank has an imbalance and this isn't just down to carbon, it's other nutrients versus the amount of light you are pumping in.
Can I spot treat?
It is possible to spot treat plants or wood that have algae growing on them. Simply by using a pipette and extracting some Neutro CO2, squirt the carbon onto the plant or wood when it is outside of the water. Wait for 10 seconds then put it back into the water. You can also do this when performing a water change (it's easiest that way). But if you leave liquid carbon on for too long you will kill the plant.
DOSAGE: Add 1ml per 50L every day. It doesn't matter what time of day you dose this product, but it does need to be added every 24 hours.

Customers praised this all-in-one plant fertiliser kit for promoting impressive growth, with many noting "plants have doubled in size" within weeks. The liquid CO2 and nutrient combo is easy to use, odorless, and safe for fish and shrimp. Some customers found dosage challenging for smaller tanks, requiring syringes for precision. One reported leaking bottles upon arrival.
- Not only are my plants flourishing in such a short time, but the algae is finally under control
- After 16 days the fast growing plants have doubled in size and it does not affect the fish
- Plants are growing so well that I'm cutting them back almost every week. Vibrant and healthy

Since using both the liquid CO2 and the neutro TY plants seem to have reacted nicely with noticeable growth.
I’ve used this fertiliser for years now following a recommendation from Aqua Essentials.
My plants are thriving and I spend time pruning and not planting now!!
Love the neutro combo. No strong smells and my plants love it also. Great price for these two
Good value thanks for prompt service 👍
I use this all the time, my plants seem to thrive on it.
Recently bought the Neutro Combi pack and what can I say? Wow! Excellent! Not only are my plants flourishing in such a short time, but following the advice from the experts here the algae is finally under control. Very satisfying watching it change from green to black and then dying.
Excellent products as always from here. I’ll be back for more very soon!
Great results
Recently purchased Neutro combo along with mixed box of aquarium plants. Appears to benefit the plants although only just recently started using this fertiliser. Dosage is a bit tricky as have to guess amount as dosage measure marked only from 10 ml
That's ok - with fertilisers better to have more than less. If it's still a concern we do sell 10ml syringe that is very accurate.
Very difficult to dosage even with a small syringe if a tank is smaller than 100 litre .But awesome results.I have been using it for 16 days and the fast growing plants have doubled in size.The slower growing ones have also increased in growth.And it does not affect the fish or the shrimps.Great product.
I have been using the fertiliser for longer than the CO2 but I have noticed my plants are definitely looking healthier, greener and growing better than before. Would recommend for sure!
Slightly difficult to measure the right amount for my small tank but I have an old liquid paracetamol syringe and that does the job perfectly. Plants I've bought from local aquarium specialists have never lasted but this stuff is looking very promising and the plants are stunning
Didn't want to go to the expense of a co2 set up, so purchased these products, after 2 weeks of use there is a noticeable improvement of plant growth, the fast growing ones have almost doubled in size, will be ordering some more when this runs out
good so far 2 weeks of daily doses and all plants are looking healthier
I use this all the time, works well and supper easy.
Very easy to dose due to the bottle design.
So far I've only used these item's for couple of weeks and all seems OK, plants are all ok and still growing so I assume it's working.
Early days but plants are looking good
Haven’t used the co2 but neutro is good
Yet another excellent product from Aqua Essentials. First class customer services and delivery arrangements. After a few days I can already see the difference in my plants.
I've been using these products for over a year and they keep the plants healthy and growing well in my tank
Both bottles were leaking when they aarrived so assume they are filled from larger containers? No instructions regarding the integral dispensing element but nevermind.
Despite needing only 1,2 or 3 cc for smaller tanks there is no pipette or other dosing instrument.
Too early to say what it does for my tank/plants/algae
A great liquid fertiliser and Carbon. I've recommended this to several people who really like it.
I have a 34L tank and dose 1ml of each daily (slightly overdose the carbon and underdose the ferts.) both bottles will last well over a year.
Definitely worth buying, stop reading the reviews and buy it!
Easy to use measuring system, a lot better then faffing around with measuring cups ect
Haven’t used it long term yet but I’m sure it’ll be great!
Can't believe I never thought of looking after the aquarium plants as well as the fishes! The plants do seem to be perking up now, but I think it's still too soon to say. I may have been using plants before that were sensitive to the aquaria temperature (22 deg), so they didn't last long. Hopefully this new 'gardening' and the right plants may prove the answer! So glad I got this double pack!
Ordered a small quantity to see what a difference it could make to my planted aquarium...it really does make a difference in a short time,I'm already thinking of needing to trim some vigorous plants!
I like this,I set up my tank last year and still have a lot of the plants I bought then from Aqua growing in my tank and I think it's down to using these
Had problems with my plants caused by my previous "complete fertilizer",Richard suggested this when i asked his advice and i'm happy to say it works.
Thank you Richard :)
this keeps my plants looking good
Ive been using these products for a year or so and they do the job. Plants are growing so well that I'm cutting them back and pulling bits out almost every week. The whole tank looks vibrant and healthy
started using this and my plants are thriving and my algae problem seems to have disappeared .Best move ever
always FOUND THIS TO BE GOOD PRODUCT.
It works, 'nuff said!!!
