Guess I need to make a couple changes

I’ll start off with I use DI water I can get from the water plant, (free) it’s used for testing at the different plants in the city. With the exception of phosphate and a little high on cal and mag my tank looks great.

However when it comes to growing any kind of sticks starting with the easiest they turn white. I mount them in 200 - 250 par the lights were setup with a par meter, tank is 9 months old. I have Gsp, torch, 2 hammers, shrooms and pally’s, cabbage coral.

1.027
0 nitrite
0 Ammonia
20 nitrate
1.0 phosphate
450 calcium
1500 mag

Im considering running GFO for phosphate, Because I don’t know what to do. And yes I have only replaced my AK, an Mag
Test kits from the api, the Rest are on the list.

I have access to D/I water as well but decided not to use it because a lot of the water has been sitting for a year or more and I just don’t know if I trust it. Your phosphates are fine to me. I wouldn’t mess with them until they start getting over 2.0 but a simple water change can bring them down some as well. My take from talking to others on here that run successful tanks is that 1.0 phosphates is perfect. If you run your phosphates at .2 or something they could fall off over night and risk a cyano or Dino outbreak. I personally think your numbers look good.

Thanks, guess i'll wait it out and get a better tester, then go from there.
