kH tester? What??4Dkh water is distilled water mixed with a exact perfect amount of baking soda to bump up the KH. So its basically water. that has the Carbon hardness of 4dkh. You can buy the water certified or make your own with a KH tester
I really hope you have success with the DIY CO2. I tried it and failed miserably with that amount of light, but I wasn't dilligent about it and I don't think I had a big enough DIY setup. For my setup, anything less than 3bps causes algae problems for me on an 8 hour photoperiod. I am going to add you as a buddy so I can (hopefully) track your progress on this one. Good luck!baking soda? ok i will try to find the right forumla.
and yes biscuitslayer, this is the tank with the 130W light. Its a lunar delux with 6700K lights right now. im really hopeing it works out.
yeah, i didn't know there was a kH tester. I should have grabed some from school when I had the chance.
well i'm going to search for the forumal and try it.
