My dry ferts and crypts came in today from green leaf aquariums and planted aquarium central. I would recommend dry over flourish fertilizer for heavily planted tank. Reason being is, it's cheaper in the long run. I was running out of flourish 250ml bottles very quickly. I'm going to try the PPS-PRO method and experiment.

. Also, I would put half cap full of flourish excel into each bottle. Planted aquarium central gave me some extremely healthy cryptocoryne undulata. I only ordered 2 crypts, but she gave me 3 instead. It definitely put a smile on my face and I will order some more.
