Can anyone tell me if this plant will grow without co2? I only use excel and other ferts in my planted tank.

Hi Kdog,

Absolutely!

10 gallon, no CO2 (but Excel/glut); EI fert dosing; low light [email protected] (P. erectus @ left rear)

The other question I have is the store where I can get these have them in a co2 tank; will the change from co2 to excel be ok?

Hi Kdog,

They will grow slower using Excel/glutaraldehyde as the carbon molecule source but other than that they should make the transition just fine. Just an FYI all of the plants in the photo above were grown emersed and then planted in about August 7th; the picture above was taken on October 17th. The point being that plants can adapt fairly quickly to changing environments as long as they have what they need for growth.

Here is what the tank looked like on August 7th after planting

What kind of substrate you have there? I have Eco-complete. Do you think that will be fine?

Hi Kdog,

The substrate in the 10 gallon pictured above is Safe-T-Sorb #7941 a calcined clay product with high cation exchange capacity (CEC); 40 lbs costs about $6.50 at Tractor Supply Company.

I have not used Eco-Complete but many on this forum have, hopefully they will provide their experiences. That said Eco-Complete states it has many of the micro-nutrients that plants need for growth but no macro-nutrients such as nitrogen, phosphorus, and potassium so those nutrients will need to be provided.
