Thanks for responding- I was beginning to think that this was a lost cause.
I am not sure how to tell the difference in the two types of RO units you stated above. If it helps you, here is a picture of the unit I have
I'm really going to show my ignorance on this one. Can I measure Ca and Mg with a GH test kit?
If I remember right, my water from the tap is KH 5 degrees- but I'll double check that when I get home today.
I have a 60g Tall tank. The dimensions are 48"X12"X24"
I have a 2X55w kit from ahsupply.com and I do have a pressurized Co2 system.
I have been toying with the idea of adding a little more lighting but I'm not sure how to go about it. I think another 2X55 is overkill.
For my substrate I put in a laterite mix with regular epoxy coated gravel that I got at my LFS. This may not be good, and I'm willing to change it since the contents of my tank have gotten dusty since all the construction going on at my house with the floors.
Thanks for your help
Adam
