Grobbins48 Interesting. I want to do something similar. I have a CO2 regulator with two outlets and I'm trying to figure out how to do this without buying a second controller. The 40B will be planted much lighter than my 75g, so I'm less concerned about getting optimum CO2 than adding a bit to enhance growth. How are you hooking your's up?
I have the same thought process, just wanted to add a bit of CO2, not max this tank out. The 75 I pump lot's of CO2 in.
I simply put a 'T' on the regulator output with two barbed adapters. They each run line to Dwyer RMA 151 SSV flow meters. I use those to dial the rate in properly. The CO2 controller is set on the 75 to a safety level, so if there is EOTD or something happens I can save the tank. I dial in the CO2 to drop to just before shutting off by the controller on the 75 gallon. It has been working quite well for the past couple of weeks.
The CO2 on the 40 breeder is something like 10cc/min, enough to get it in the water column, but not so much that I worry about gassing the fish!
That does look good...is it experiencing a deficiency or have you come across a sub-species?
Definitely some sort of deficiency- but I am no expert here. I only put in 5ppm NO3, and 2.5 each of PO4 and K. Mg I didn't really add at all until this weeek, water is naturally 7ppm. We will see if anything changes!
