<p>You're fine on nitrates. Actually in a pretty sweet range. You just don't have enough uptake at the moment to bring down your levels. At much higher levels, nitrates will start to interfere with your fishes' abilities to bind oxygen to hemoglobin, but you've got a long way to go before that happens. In the meantime, the one negative effect can be aphid infestations and higher aphid reproductive rates. Those suckers love high nitrates. If you're having bug issues, dropping your nitrates…</p>

<p>Check out this fact sheet, very helpful. Notes 300-400 mg/L is low end of toxicity range for tilapia, mg/L is also equal to ppm. Partial water change will help bring Nitrate down quickly.</p>

<p>Hi Roger,</p>
<p>A reading of 160ppm NO3 is not considered high in AP, but actually ideal for growing leafy plants. This amount of nitrates are not considered suitable for fruiting plants, although they do grow them. If you don't have a lot of growbed space and want to bring down the reading, go for a vine crop. In my experience, having bitter melon and cucumber plants etc in an AP system will quickly get you to low nitrates levels in a short time and they can be planted in a corner of the…</p>
<p>Hi Roger,</p>
<p>A reading of 160ppm NO3 is not considered high in AP, but actually ideal for growing leafy plants.

In my experience, having bitter melon and cucumber plants etc in an AP system will quickly get you to low nitrates levels in a short time and they can be planted in a corner of the GB. The vine growing crops are a way to effectively increase GB size without the expense of added construction.</p> More Plants, a lot more.

<p>More Plants, a lot more. I am in the same boat and the only way I have been able to drop Nitrate levels was but putting more, established plants in the grow bed.</p>

<p>Great picture, by the way. Everything looks pretty healthy! If your plants look healthy and your fish look healthy, then I don't think you should worry about your system. If you're concerned, just keep a close eye on things.</p>

<p>160ppm should not be a problem for fish. I don't know about other species, but I recall tilapia being able to handle as much as 700ppm of nitrates. Sounds to me like you have some leeway before you have a problem, but I could be wrong.</p>

<p>I should also note the fish seem to be doing great. They're happy to eat and don't seem stressed.</p>
