I've been having troubles with my duckweed (I know its supposed to be immortal but I apparently found a way to kill it off)
Oh! Let me in on that secret! I have a LOT of it to kill off.
I really want to go full planted 90% of my tank is plastic plants.
I also dose weekly with API leaf zone and every other day with CO2 booster for the amazon sword. I've only been doing that for a couple of weeks and I'm unsure if it is actually helping.
It is helping. Go ahead and get more plants. Do you have a good light?
EDIT: I will also take a water sample with me to the petstore to double check my results.
Always good to double check! Make sure to ask for the actual numbers. Don't settle for "it is good' or 'it is bad'.
So I'm pretty sure the secret to killing off Duckweed is to stare at it daily checking to see if there is more than the day before. I'm guessing its just shy and doesn't perform well with an audience.
My lighting isn't good enough right now currently at .75 watt/gal. But I could be at 1.5 watt/gal tomorrow, I have the fixture it just isn't set up yet.
I want to add more plants I just have to see what I can get my hands on, I really want to try a java moss wall or carpet.
I didn't see your post before I left and I accepted the "It's good" from the guy at Petsmart... Next time I'll get the numbers, I'm in there more than I should be (ever since the last LFS closed).
^What Diana said.
Also, really hard water is fine for 90+% of FW plants and fish. And if you were to reduce the hardness to a point that would be fine for the other <10% of FW plants and fish, then you'd likely have a problem with keeping <10% of hardwater plants and fish. So you're good. Also, a couple seashells and some cuttlebone won't do a whole lot. Crush them up and you have a more extreme change, but still probably insignificant given your starting parameters anyway.
And while test kits for a bunch of stuff are interesting and may help you to understand how much of this stuff works, there's a really good chance you will rarely, if ever, use them past the first 6-12 months. So don't pour a lot of money into them. API kits from Amazon are fairly reasonably priced.
OK I won't worry about the hard water.
After testing my parameters with the API nitrates test kit I got 0~5 nitrates (not exactly yellow but pretty close) which I'm pretty sure isn't possible (I would think it would be higher but I did do a partial water change before leaving to the store.)
I looked online and saw I should've shaken the bottle for a couple of minutes and not 30 seconds since its been sitting on a shelf so I'll try again tomorrow when the lights are on. If the number is still 0~5 would I need to start fertilizing if I added more plants?
Ok recheck is done now that I am fully awake and the tank lights are on, the nitrates are 10 ppm. I will check again to make sure it was just a bad test yesterday and not my tank jumping 5ppm a day
