[APD] Re: RO/DI setup vs. CO2 setup
"I have just purchased a new test kit and now have numbers that
are on the scale at least.
Alkalinity around 80 ppm
Total hardness around 120 ppm."
Those numbers don't seem so high. Read this:
A quoted section:
"Water hardness follows these guidelines:
0 - 4 dH, 0 - 70 ppm : very soft
4 - 8 dH, 70 - 140 ppm : soft
8 - 12 dH, 140 - 210 ppm : medium hard
12 - 18 dH, 210 - 320 ppm : fairly hard
18 - 30 dH, 320 - 530 ppm : hard
higher : liquid rock (Lake Malawi and Los Angeles, CA)"
"What is the primary concern with phospates? Is it just because
algae really enjoy them. I have several cory cats and sharks to
do the cleanup of the algae."
Yeah, algae can get going faster than the cleanup crew can help.
When I used Discus Buffer way back when, Black Brush Algae (BBA)
ran rampant. Dunno how long your tank has been set up, but I
wouldn't do it that way.
You may also want to read through this:
http://www.thekrib.com/Plants/CO2/alkalinity.html since a high
amount of PO4 can mess with the alkalinity reading. Are those
numbers above from the tank or from the tap?
