Aquaforest PO4+ Lab 200ml (phosphate)

Description

Po4
An agent for raising phosphate levels. Product intended primarily for aquarium owners with a small number of fish or very intensive filtration
The use of strong filter media, nutrient depressants and skimmers can cause a sudden drop in phosphate levels in the aquarium. Phosphorus is an important element for zooxanthellae – photosynthetic algae that live in symbiosis with corals. With zero phosphorus values in the aquarium, the zooxanthellae simply “starve”. A zero PO4 level in a saltwater aquarium makes it much more difficult to reduce NO3, so a precise phosphate value correction is necessary.
AF PO4 + is a product intended primarily for aquarium owners with a small number of fish or very intensive filtration. Heavily sterilized water, devoid of nutrients, causes problems with coral dyeing, bleaching and significantly inhibited growth. LPS corals are particularly sensitive to low nutrient levels. AF PO4 + allows you to accurately correct phosphate levels and quickly restore the desired values. The ratio of nitrogen to phosphorus should be 16:1.
AF PO4 + is a product of the Aquaforest Lab line created for aquarists who want to have full control over the parameters in their tank. Before use, we recommend that you test both NO3 and PO4 levels and dose them gradually until the desired phosphate level is achieved.
The product in a convenient and safe package, for use in a marine aquarium.
Dosage

1 ml of AF PO4 + added to 100 l of aquarium water increases the phosphate level by 0.01 mg/l (ppm)
The maximum recommended daily dose is: 1 ml/100 l
The optimal phosphate (PO4) value for a reef aquarium is 0.03-0.05 mg/l (ppm)
Only use when the PO4 level is very low

Keep away from children. Product for aquarium use only. Not suitable for human consumption. Keep in a cool, dry place away from direct light.
Product intended for professional use only

Aquaforest PO4+ Lab for Raising Reef Phosphate in SG Tanks

Plenty of Singapore reefers run heavy filtration, skimmers and carbon dosing, and the result is often phosphate that reads flat zero on a hobby test. PO4+ Lab is the tool we reach for when corals show pale tips and shrinking polyps from nutrient starvation rather than light stress. It lets you nudge phosphate back into a measurable range so zooxanthellae keep feeding the colony, instead of chasing a sterile, ultra-low-nutrient tank that bleaches sensitive SPS.

We always tell customers to dose conservatively and re-test. Add a small amount, wait, then check again with a reliable kit before topping up, because phosphate can climb faster than expected once your export systems are dialled back. Track nitrate alongside it, since a balanced N-to-P ratio is what actually drives colour and growth, not phosphate alone in a vacuum.

This sits in our water testing and care range. For the bigger picture, see our guides on phosphate management and raising nitrate in saltwater tanks so you correct both nutrients together.
