"I have a nice 135 gallon planted tank. The plants were nice, they grew ever so slowly and appeared healthy yet the color was not great. Corn white leafs and some paleness to the general look. I was using both in gravel ferts and bi-weekly doses of seachem products. I ordered the 2hr Aquarist fertilizer. in three days ( one dose) I thought I noticed some greening up of the riccia. In one week and two doses it was obvious that the ground cover ( Cuba) and the riccia were definitely greener. Two weeks on and the planted aquarium has taken on a whole new green green, healthy look! GREAT product."

APT has been an absolute joy to use! My plants have experienced significant growth and colouration when paired with CO2 injection. What is best is that the product contains all the macro, micro and trace elements all in one! The dosing regime is also really simple and convenient, perfect for me even with my tight schedule. It saves me the time of mixing my own nutrients and saves me the money of getting all these nutrients separately. Thank you for making such a great product right here in Singapore!

"Firstly I'm a beginner aquascaper. In my very short aquascaping life I used many fertilizers like ADA, EI, APK and APT. But most of all I like APT most. Because it's cost effective [and] so amazing. You can see changes within 2 weeks. Also I'm a lazy man [so] it is most suitable...for me 'cause l need to change water once in two weeks? Now my plants are more bright and healthy. I recommend to you that you need to sharp[en] your scissors 'cause you need to trim more and more after you use APT. Thanks 2Hr Aquarist for APT."
