Due to my time restrictions I was forced to invest in fairly cheap Eheim Liquidoser. I have been using it for few months now and I wouldn't setup another planted tank without one.
55G heavily planted w/ hi-tech equipment
My fish load and feedings are heavy (until I get rid of my Rainbows) so I'm assuming I'm getting some NO3 from waste etc.
Doser holds 100ml and since I see this tank only on the weekend, I either have to spread 100ml over two weeks or have only enough for 1 week. I went with Second choice.
ML calculations:
- Max mls per day is ~8mls
- Max mls per 7 days is 56mls
NO3:
- 1/2 tsp of KNO3
= ~10ppm weekly
PO4:
- I was using KH2PO4 and adding that to Liquidoser at the beginning, now I'm adding it directly to the tank
- 1ml x 4 per week = ~2ppm
Trace
- I have been using TMG (Tropica Master Grow) for years so I'm sticking to it. 5 liter container should last me for a long time.
- Concentration - 20mls/50Gallons but you should or can double that recommendation.
- In my case I'm going for 30mls per 1 week
FYI,
5 litter container w/ addition of 30mls per 1 week "should" last me for ~3 years. This container cost me $50 through BigAl's
Iron
- Concentration - .5-1ml/10Gallons
- I'm going to increase the dose b/c it worked for me in the past
- Final volume 26ml per 1 week.
Calcim
- Adding 1/2 tsp of Turbo Calcium at weekly water changes
FYI,
2 litter of Seachem Flourish Iron is only $20 and should last you for a while as well.
Final breakdown:
- 30ml TMG
- 26ml Fe
- 1/2 tsp of KNO3
- separate addition of KH2PO4
- seperate addition of Turbo Calcium
!!! Notice no K addition.
If you're using KNO3 as your primary source of N, for 1.14 ppm of N - you're already adding in 3.15 ppm of K.
This is just a "general formula" and shouldn't be used as THE ONLY WAY to go. Play around w/ numbers, look at plants and figure your own receipe.
