Using more then the manufacturer recommends..
So I got a brand new API Pondmaster test kit for the pond, and I figured although it doesn't do nitrates, it tests pH, Ammonia, nitrites, and phosphates. Everything was perfect across the board, 7.0 pH (tap is 7.6 according to the kit, so assuming thats from CO2), 0 ammonia, 0 nitrites, but 0 phosphates?? I tested the tank approx 5 hours after I dosed phosphates, and it was already gone?
I've been using Seachem's Aquavitro line following the dosing guidelines on their website:
Day of the Week Product Dose
Day 1, 3, 5 propel 1 inner cap (7 ml) per 70 US gallons ( 280 L)
activate 1 ml per 36 US gallons (136 L)
synthesis 1 ml per 36 US gallons (136 L)
Day 2, 4, 6 propel 1 inner cap (7 ml) per 70 US gallons ( 280 L)
envy 1 inner cap (7 ml) per 40 US gallons (150 L)
Day 7 Water Change
Propel is a concentrated (10,000 mg/L) source of ferrous iron.
Activate is a concentrated (6,000 mg/L P) phosphorus source
Synthesis is a concentrated (32,000 mg/L N) nitrogen source
On the bottles: use with activate to provide nitrogen and phosphorus in a 5:1 N:P ratio
Envy is micros and other vitamins, too many to list
The tank in question is a 40 gallon long with 2 HOT5 54 watt bulbs, CO2 running at an uncountable amount, a split 8 hour lighting period (battling algae). I just use gravel with root tabs under the HC (yes my HC is growing in gravel, I planted it when I was a noob, but it's bright green and happy), DHG, and Rotala. My plants are happy and well rooted despite the algae issues. The Algae explosion was from the change in lights from 1 HOT5+T8, to two HOt5s, after my ballast died in the T8. Trying to figure out the new lighting period, but I notice the 3 hour break in the 8 hour lighting period is helping. Also put in barley yesterday after a big tank cleaning to keep it away....
There is also a handful of wisteria stems, lots of java moss, some what I thought was elodea (grows like a weed, drives me nuts sending baby plants everywhere around the tank), and a coconut fiber ball with what I believe is a lily (which sent up a flower a few weeks ago, and sends up leaves to the top too) and a fern of some sort also in the ball.
So I was curious... when is it okay to dose more then the manufacturer suggests? I wouldn't have expected the plants to use up the phosphates that quickly, and I'm curious to see where my other levels sit. They are all growing quite well, but I'm wondering if maybe they would benefit from a small increase?
When I tested with test strips I had, I got a nitrate reading of 20 ppm, taken at the same time as the other test. Nitrates and phosphates are dosed at the same time too, this was before a water change.
Would it be worth it to increase the phosphate and nitrate dosage? Currently I use a 1 mil pipette and dose 1 mil of each on Days 1, 3, and 5. I've been dosing extra phosphates in my 10 gal, but only to kill Diatoms, and only inhabitants are Nerites, so I don't know if there's a negative effect or not, but I assume if it's at 0ppm in 5 hours I should be safe?
