Iím confused. So vary, vary confused.
Decided to go with a sponsor on my fertís. PMDD from Greg is on the way. Yes it is lazy, yes it is not optimal. But it was a place to start.
Ok here is the dilemma. Per EI
, no3 uptake is 1-4ppm daily.
Per the krib
, a good starting dose on my 58 gallon tank would be1/12 ml to 1/6 ml per 10 gallons (tank size I think) Ė ok on the top side of that, 1 ml per day.
Per another site http://www.csd.net/~cgadd/aqua/art_p...osage_calc.htm
assuming I have about 40 gallons of water (net of substrate etcÖ) 1 ml of solution will only change my nitrates by .14ppm (and they target 5ppm).
Ok, assuming dosing daily, total weekly dose(with no absorption) would be about 1 ppm, with a maximium acculuation of 2ppm (roughly, assuming 50% water changes). My actual changes are closer to 40% - so it would max out a bit more than that Ė assuming no absorption.
So my confusion where did I go wrong in theses calculations. They are too incosistant with each other. Does anyone do pmdd, and at what rate? Has anyone looked at this to tell me why my math bites?
58 gallon tank
250 watt hqi
will be adding diy co2, might pressurise latter
light/moderate planting, but will fill in quickly I hope (have maybe 20 plants, but lawn (chain swords), wisteria and val needs to fill in some. It will become heavily planted I hope.
Oh, guess I should mention that I used to homebrew, and plan on doing some in the future. I wanted to do diy co2 for astetic reason, really did not want to put my 20lb co2 tank in the living room- although have less problem putting the 5 gallon carboy bubbling into the aquarium. (currently have two batches of wine about ready to bottle, so will be doing beer shortly).
aquarium had some alge issues before the light came on, but they went away for a bit. Got the tank fairly planted this weekend, but the alge is back with a vengence. My bet was lack of co2 is limiting the plants, but recognize they are also starving for nutrients as well.
