AquaLabs Max Grow is a complete aquarium fertiliser for densely planted, CO2 injected aquariums. Nutrition is non limiting, so growth is never held back by what is available in the water.

Suited to stem plants, carpets and fast growers under strong light, where demand is genuinely high and limiting nutrients means stunted tips and pale new growth.

Dosage

Shake well before use. Dose 1 pump (2.0ml) per 30 litres, 3 times a week. Recommended with a 50% weekly water change.

Storage

Store in a cool, dark place away from sunlight.

Analysis

Parts per million added by 1 pump (2.0ml) per 30 litres.

Primary macronutrients

Nitrate 6.50ppm
Phosphate 2.00ppm
Potassium 6.02ppm

Secondary and micronutrients

Magnesium 0.02ppm
Iron 0.150ppm

Plus trace elements. Bars are scaled within each group, so you can read the ratio between nutrients dosed at similar levels. Primary macronutrients are supplied in far greater quantity than secondary and micronutrients.

FAQ

Is Max Grow the premium version of the range?

No. It is the right formulation for a tank with high demand and the wrong one for a tank without it. Dosing Max Grow into a low tech tank with a handful of anubias will not make them grow faster, because growth there is limited by carbon and light rather than by fertiliser.

The extra nitrate and phosphate would simply accumulate in the water.

Why the larger water change?

Max Grow adds considerably more nitrate per dose than the rest of the range, because a densely planted CO2 tank consumes it that quickly. A 50% weekly water change keeps levels in range in tanks that are not consuming everything dosed.

What nitrate level should I be aiming for?

Around 10 ppm suits most planted aquariums. For the deepest reds, 0 to 3 ppm works, but only where a rich aquasoil is supplying nitrogen through the roots. Over inert gravel that range starves the tank rather than colouring it.

Which fertiliser does my aquarium need?

My plants look deficient. What should I check?

In a CO2 injected tank, most symptoms that look like deficiency turn out to be CO2, flow or light. Rule those out first, then check whether the affected leaves are new growth or old, which tells you which group of nutrients to look at.

Nutrient deficiencies and how to identify them

I am dosing iron but still seeing pale new growth.

Check your pH. Iron precipitates out of solution as pH rises, so in harder alkaline water a large share of what you dose can become unavailable before the plants reach it. More iron does not fix this.

All AquaLabs fertilisers use a combination of EDTA and DTPA chelated iron, which holds availability across a wider pH range than EDTA alone.

How pH impacts nutrient availability

Is it safe for shrimp and snails?

Yes, at the recommended dose. All AquaLabs liquid fertilisers contain copper, because it is an essential plant micronutrient and plants cannot grow properly without it. The amount is a trace, dosed far below any level shown to affect invertebrates.

The copper is also EDTA chelated. Copper toxicity is driven by the free copper ion rather than total copper, and chelation binds that ion and reduces how much is biologically available.

Dose as directed rather than estimating, particularly with sensitive caridina.

Do I still need root tabs?

For heavy root feeders such as swords, crypts and larger stem plants, yes. Liquid fertiliser feeds through the water column and leaves. Root tabs feed the substrate directly.

They are also worth adding in inert substrates like sand or gravel, and in aquasoil more than a year old that has exhausted its nutrients. Enrich Root Tabs can be used alongside any liquid fertiliser.

Can I mix it with other AquaLabs fertilisers?

Dose one complete fertiliser at a time rather than combining two. Each is a complete formulation, so running two together doubles some nutrients and unbalances the ratios.

Enrich Root Tabs are the exception and can be used alongside any liquid fertiliser.

I am switching from another fertiliser. Anything to watch?

Introduce it over about two weeks rather than all at once, particularly if you are moving from something much leaner or much richer. Dose part of the new alongside part of the old and shift the balance gradually.

Plants adjust to what is consistently available, and a sudden change can cause a short period of instability.

 

Description: AquaLabs Max Grow is a rich aquarium fertiliser designed for densely planted aquariums with minimal hardscape and CO2 injection. It is tailored to achieve the fastest and most lush growth. This special formulation allows all essential macro and micronutrients to be delivered in one convenient bottle. It is safe to be used with fish, shrimp and snails.

Consider this formulation if you are setting up a plant centric aquascape or one with inert substrate. The non-limiting nutrient delivery method allows plants to thrive and rules out nutrient deficiencies as a cause of algae. Aquarium plants will grow much faster meaning the hobbyist can achieve their desired results sooner. If you are looking for more controlled growth and less maintenance, consider AquaLabs Lean Grow.

Dosage: Shake well before use. Dose 1 pump (2.0ml) per 30 litres, 3 times a week. Perform a 50% water change weekly to retain nutrient levels within desired ranges.

Storage: Store in a cool, dark place away from sunlight.

Analysis: 1 pump (2.0ml) in 30 litres yields the following:

  • 6.50ppm Nitrate

  • 2.00ppm Phosphate

  • 6.02ppm Potassium

  • 0.02ppm Magnesium

  • 0.15ppm Iron

  • + Trace Elements
