Hey guys, I currently set up a 10 gallon tank. I have been trying to find my nutrient uptake so I can fertalize the right amount. It seems like I have to add a lot of phosphate and nitrates to keep my levels where I want them to be. Just yesterday I added 8 ml of nitrate and 7 ml pf phosphate, and today when I tested (lamotte test kits) I had 4ppm nitrate and .02 phosphate. Is that normal? I do have quite a bit of light, 72 watts. 36ppm co2 pressurized. The only plants in there are glosso, cabomba and red ludwigia. I have green spot algae and knew I needed my phosphate higher, but it seems when I dosed that much yesterday, I have a lot more algae on the ludwigia. The glosso is getting bga on it too. I dose with all seachem products, are they weaker then Greg watson maybe? I get kind of worried dosing that much but the tests are still comming out low. Also, the ludwigia is showing up with cupped leaves with a very light pink color, not a rich red. I have a gh kit on the way, the one I have now is impossible to tell. If you guys could help me it would be greatly appreciated. By the way, great site .
