Thanks for the reply. I read up on these before buying when they were recommended to me on this forum.
I am currently using Thrive but had been experiencing higher nitrates than I would have liked. I now also have ThriveC at my disposal. I got this because of the description as being for low tech tanks and tanks with higher levels of nitrates.
Now that a lot of plants and nitra-zorb have been added I am seeing pretty low nitrate levels, so I am sticking with Thrive for the time being.
I have a low tech, low/medium light tank. Which Thrive would you say is more appropriate for my scenario?
My question about dosing Thrive vs ThriveC was more or less to establish the fact that if I switched to ThriveC, the bottle would be used up at twice the rate of Thrive...which seems to be the case.
