UNS Plant Food MAX is a concentrated liquid fertilizer designed to support demanding planted aquariums. Formulated with a complete blend of macro and micronutrients, it promotes stronger, faster aquatic plant growth.

It is ideal for established setups with dense plant mass and higher lighting, as well as aquariums with nutrient-demanding plant species. As plants mature beyond the initial acclimation phase, it provides the consistent nutrient support needed for continued healthy growth.

Safe for most freshwater fish and shrimp when used as directed, Plant Food MAX is a reliable solution for aquascapers who want vigorous, vibrant plant growth.

Choosing Between Plant Food MAX and MIN
Plant Food MAX is ideal for aquariums with dense plant growth, nutrient-demanding species, and setups with higher lighting and CO2 injection. For lightly planted tanks or setups with nutrient-rich substrates, Plant Food MIN offers a toned down approach to maintaining plant health and steady growth.

- Supports faster growth, vivid color and helps address nutrient deficiencies.
- Best used in balanced systems with higher lighting and CO2 injection.

Improvements seen in just days!

"Recently set up a Fluval Spec 5 planted tank and picked up the UNS Plant Food to go along with Seachem Excel (not trying to do a CO2 setup yet, just getting started). Unfortunately I had to evacuate due to CZU fires, so I topped off my tank dosed some ferts and left the light on -- hopefully there is something to come back to!"

— David A. (5/5)

Plants blew up after 2 weeks of use

"I got this a few weeks ago and have done 4 pumps since then in 6gallon. Smaller pumps but within the first week my low tech plants blew up and started taking on much more co2 as well. They pearl like crazy now and I've had to trim them down after the two weeks. I also house amano shrimp and many snails and they seem to be completely unaffected. I've done two water changes since then of about 30-40% with no issues whatsoever. My TDS did rise a bit after use by about 50 which was still not an issue as my water was still super clear and safe for my shrimp. I would definitely recommend giving this a try and I was honestly surprised by how much it changed within just 2 weeks!"
