Masterline All-in-One Soil aquarium fertilizer for plants

Masterline All-in-One Soil is a premium liquid fertilizer that provides complete nutrition for planted aquariums. With macro and micro nutrients in one formula, it simplifies dosing and ensures plants receive everything they need for healthy and balanced growth. 

Designed for aquariums with nutrient-rich substrates, it encourages plants to feed more from the soil, resulting in stronger pigmentation, slower but healthier growth, and long-term stability in your tank.

Safe for shrimp and compatible with all aquarium livestock, this fertilizer is ideal for beginners who want simplicity and experienced aquascapers who wish for precision.

Daily dosage and usage

The recommended daily dose is 1 ml per 30 litres of water. This amount provides a balanced supply of nutrients to sustain plant health. Increase the dosage to 3 ml per 30 litres for tanks with UV lamps. Add a triple dose to restore balance after water changes of more than 30 percent.

Each 1 ml per 30 litres provides:

  • 0.6 ppm NO3
  • 0.1 ppm PO4
  • 0.75 ppm K
  • 0.06 ppm Mg
  • 0.045 ppm Fe

Recommendations and precautions

To get the best results from Masterline All-in-One Soil, use it in aquariums with nutrient-rich substrates like aqua soil or Masterline Root Caps. Pairing it with Masterline Carbo can further enhance plant health and colour.

  • Do not contaminate the solution with aquarium water
  • Store in a cool, dark place at room temperature
  • Keep out of reach of children and pets
  • Use for aquarium purposes only

The best all-in-one fertiliser I have used

MasterLine All-in-One Soil from School of Scape has transformed plant growth in my aquascape. Since switching from my previous fertiliser system my plants have deeper colour saturation, faster new growth, and the overall vitality of the tank has improved noticeably. The formula is specifically designed for aquariums with active soil substrate. The 1ml per 30L daily dosing is simple and clear. School of Scape stocking this premium European brand in Australia is excellent.

Simpler than dosing multiple bottles separately

Before MasterLine All-in-One Soil I was dosing macro and micro nutrients from three separate bottles. Switching to a single all-in-one has simplified my maintenance routine significantly while producing equal or better plant results. The balanced formula means I do not need to worry about individual nutrient ratios. School of Scape stocks this trusted European fertiliser brand in Australia. My plants have never looked better.

Plant pigmentation is noticeably deeper

The most immediate effect I noticed after switching to MasterLine All-in-One Soil was an improvement in plant pigmentation. My red stem plants became noticeably deeper in colour and the green plants took on a richer more saturated tone. The formula is designed to encourage deeper pigmentation alongside healthy growth and the results confirm this claim.

Safe for shrimp – no losses whatsoever

I was initially concerned about using MasterLine All-in-One Soil in my heavily stocked shrimp tank. After three months of daily dosing at the recommended rate my shrimp colony is completely healthy with no losses. The copper content is within the safe range and the formula is specifically described as shrimp-safe. Complete confidence in this product.

Works in combination with Scaper Soil substrate perfectly

MasterLine All-in-One Soil was designed specifically for aquariums with active soil substrates and when used with School of Scape Scaper Soil the combination is perfect. The formula encourages root feeding and the active soil provides an excellent nutrient base. My plants are growing denser, the pigmentation is deeper, and the overall tank stability is excellent.

Beginner-friendly dosing – impossible to get wrong

MasterLine All-in-One Soil is beginner-friendly in the best possible way. The dosing instruction is a simple 1ml per 30L daily and the formula is balanced to provide everything plants need without the risk of over-fertilisation. For aquascapers who want excellent plant growth without complexity this is the ideal product.

Algae levels remained low after switching

A concern with any fertiliser change is whether it will trigger algae outbreaks. After three months of MasterLine All-in-One Soil my algae levels have remained consistently low. The balanced formula prevents the nutrient imbalances that typically trigger algae. School of Scape provides this quality European fertiliser to Australian hobbyists.

The graduated measuring cup is a great practical touch

MasterLine All-in-One Soil comes with a graduated measuring cup that makes precise dosing very easy. The markings from 2.5ml to 20ml allow accurate measurement for any size tank. This practical inclusion reflects the thoughtful product design philosophy of the MasterLine brand.

My demanding red plants are thriving

I grow several demanding red stem plants that struggle under inadequate fertilisation. Since switching to MasterLine All-in-One Soil every red plant in my tank has improved. The colour is more intense, new growth is more vivid, and the overall health of even my most demanding species is noticeably better. School of Scape stocks this premium fertiliser at a fair price.

Good value for the quantity provided

MasterLine All-in-One Soil provides good value considering the quality and concentration. At the standard daily dose of 1ml per 30L a 500ml bottle lasts a considerable time even in a large planted tank. The investment in a quality fertiliser is justified by the visible improvement in plant health and colour.

Tom Richards
Noticeable improvement within two weeks

Within two weeks of switching to MasterLine All-in-One Soil the improvement in my plants was visible. Newer leaves were more vivid, older leaves looked healthier, and the overall vitality of the tank improved. This rapid visible response confirms the formula provides nutrients in a form that plants can absorb readily.

Triple dose after large water changes works perfectly

The instruction to use a triple dose after water changes of more than 30 percent is a practical and sensible feature. This replenishes the nutrients removed with the water change. School of Scape stocks this thoughtfully formulated fertiliser in Australia. Following the dosing instructions carefully has produced excellent and consistent results.

Nathan Blackwood
The best fertiliser brand I have found for active soil systems

I have tried several different fertiliser systems designed for active soil aquariums but MasterLine All-in-One Soil is the best I have found. The formula design philosophy of encouraging plants to feed more from the soil while supplementing the water column produces healthier root development and better overall plant stability.

E
Emma Davidson
Stronger pigmentation without faster growth

What I appreciate most about MasterLine All-in-One Soil is that it delivers stronger plant pigmentation without forcing excessively fast growth. Fast growth is not always desirable in a high-detail aquascape. This fertiliser provides the nutritional depth for deep colour while keeping growth rates manageable.

M
Marcus Bellamy
Used it for three months with outstanding results

Three months of MasterLine All-in-One Soil in my planted aquascape and the results have been outstanding. Plant colour is the deepest and most saturated I have achieved, growth is healthy and steady, algae levels have remained low, and my livestock including shrimp are all thriving. I have already ordered a second bottle.

Consistently excellent results across different plant types

MasterLine All-in-One Soil delivers consistently excellent results across all the different plant types in my aquascape. Stem plants, crypts, anubias, ferns, and mosses all respond positively. The balanced formula works for the full spectrum of planted tank species. School of Scape stocks it in Australia and their service is reliable.
