New house, new tank. 240 gallon adventure
Today i decided to check up on how my EI dosing is actually stacking up in the water column.
I tested GH, KH, pH, NO3.
After finding a near zero reading of Nitrate, I added the difference between (1 tsp) what I normally add (2 tsp) and the Wett's calc dosage (3tsp) of KNo3.
Right after I did this, it dawned on me that there is almost no way that a daily large pinch of flake food to over 150 assorted fish would give a 0 Nitrate reading, when I am only doing 15-20% WC weekly!
Turns out the test kit was expired.
Upon new test, with new kit, I am registering 80-100ppm nitrate! I don't know if the relatively fresh (~35 min previous) addition of dry KNo3 is creating a false high, or what, but I will test daily with no addition for next week.
So, now we have a 30% WC, going to try heavy fish feed daily
NO Kno3, 1tsp KH2PO4, 1 tsp K2SO4 x 3 weekly
40ml Brightwell Iron, 1 tsp CSM+B x 2 weekly.
For an update, here is water change time video of system. Enjoy!
