I have 2.75 wpg, plants at the moment are H. polysperma, Cabomba, java moss, a crypt, some floating plant, and dwarf hairgrass. I have pressurized co2 and I keep changing my diffusers so I'm not sure on my CO2 reading. I have a red sea vortex diffuser and a glass ceramic one, I hate both of them. I dose flourish, flourish iron, kent K, kent phos+, and some type of nitrogen fertilizer.
This is what the tank looked like a couple of months ago. I really liked it like this, but I wanted more swimming room and a dwarf hairgrass carpet, so I trimmed everything and got rid of some plants

.
This is what it looks like now. The plants grow, but they seem very slow.
also the H. polysperma sends out spouts on basically every pair of leaves, is there any way to stop this?
Many thanks,
