"It was delivered with about 10% of the liquid in the bag it was delivered in."
"I’ve been using UNS plant food min on one of my smaller tanks and decided to grab UNS plant food max for my larger aquarium. I’ve been using MAX for just over 2 weeks and the experience has been good so far."
"Works great and will last a long time. Bottle is very clean as well."
"⭐️⭐️⭐️⭐️⭐️ Fantastic Plant Food! UNS Plant Food – Max works incredibly well! My aquatic plants look healthier, greener, and are growing faster than ever. It’s easy to use and makes a big difference in the tank. The seller shipped quickly, packaged everything with care, and the product arrived in perfect condition. I’m extremely satisfied and highly recommend both the product and the seller!"
"New to the hobby! Trying this fertilizer for the first time! So far the plants seem to be immediately reacting well to it! Hope it continues. Just starting co2 for the first time as well."
"I would say it works great."
"Great stuff!! But lots from you… wished it was easier to use my rewards!!"
"A true all in one UNS Plant Food Max has become my go-to fertilizer for all my planted tanks. After just a couple of weeks of consistent use, I noticed stronger stem growth, richer coloration especially in reds like Ludwigia repens and overall healthier plants across the board. It’s incredibly convenient to have macro and micro nutrients in one formula, which saves time and guesswork. I also appreciate how clean and easy it is to dose—no clouding, no residue, and my shrimp and fish have shown no adverse effects. The formula is well-balanced, and the results really speak for themselves. This is one of those rare products that actually lives up to the hype. If you’re serious about plant health i highly recommended for both beginners and advanced aquascapers!"
"Works great"
"Recieved intact but looks like it leaked. It had white crust dripping from the opening and looked like it had lost quite a bit of the fertilizer liquid."
