High kh/ph in new tank
It's been many years since I've been in the fish aquarium hobby but just got back into it this week. Have a 45 gallon tank with a fluval 305 canister filter. I have the water temp set at 77 degrees and am going to try live plants this time around. I have a T5 HO 6700k bulb and a T5 colormax bulb for a total of 60 watts.
To start the cycling process, I put some biozyme in every day for the first 5 days then added a piece of driftwood from an established tank at a LFS. I added 3 amazon swords and 2 anbia coffefolia plants. The next day, I added three platies just to help the nitrogen cycle along. I don't plan to add any more fish until the ammonia and nitrites stabilize.
I'm not very familiar with ph, kh, and gh. Didn't pay much attention to these three elements back in my fishkeeping days. Anyway, my gh is 150ppm, my kh is 300ppm, and my ph is 8.5. My kh and ph are a little high. It seems that high kh just means that my ph will not fluctuate much in a short period of time. Are these levels acceptable for plants? Will these levels gradually decrease as the nitrogen cycle stabilizes?
Any help or suggestions would be much appreciated.
