<p>Sure thing txdurk <img src="http://www.bkserv.net/images/Smile.gif"></img> . Saltpetre is pretty much just unrefined potassium nitrate (KNO3)...unrefined in this case means that it still has about 25% or so calcium nitrate (CaNO3) in it (which is also great for plants). I've made my own from from all 'natural ingredients' (god that term sounds corny...I've not had any reason to use it in the GH system) but I'm sure you can easily just buy some. You might get flagged and probably spied on by some silly government agency or another if you…</p>

<p>So that's like what...6 cubic feet of media? Seems like you should be ok with 7 little koi. The bloodmeal, the disturbances and the too low pH probably all contributed a little to the spikes. It's probably not a good idea to tax your bio-filter with additions of N that need to be broken down (unless you have large bio-filter(s) and capacity to spare). In the future if you feel you must add some N to save your plants saltpetre would be a better choice since the N is already in the nitrate…</p>

It will also give your system a bit of a boost in potassium (which is usually good)...</p>

The GB holds 45 gallons of media and accepts 25-30% of the FT water. A complete fill-drain cycle is ~12 minutes and I turn the pump on for thirty minutes then thirty off so one complete tank change happens every two hours.

<p>Meh...just quit feeding them for a week or two, they'll be fine...wait for the bloodmeal that you added to break down (it's mostly N), and you bacteria to pick back up. Fish produce a good amount of NH4 just by breathing.</p>
<p>How big is your bio-filter anyways..? 45 gallons of media? 45 gallons total volume? Or does it hold 45 gallons of water after being filled with media..? etc...</p>

Thanks Vlad. I've gotten the PH to 6.8. I hadn't thought about the "hitchhikers". Thanks for mentioning it. The ammonia levels seem stuck now at 1.0. My bacteria doesn't seem up to the task of processing seven koi though.

<p>Yup, significantly disturbing the bio-filter has for many folks resulted in mini-spikes. They don't seem to last real long though. </p>
<p>Good luck not picking up any unwanted "hitchhikers" from the store bought plants...(pathogens and/or pests)...</p>

I may have thought of why I got the ammonia spike. Just before seeing the ammonia elevate I harvested my sweet peas so I pulled the plants from the GB. At the same time I pulled two corn stocks damaged by winds (they had deep roots). I suspect the system's ability to mitigate ammonia diminished with fewer plants processing some of it directly. To test the theory I'll need to transplant some garden center plants, flowers or veg, and hope they tolerate the tranpanting.
