First, if you do set up an AP system, don't use glue like I did. You need to be able to take things apart and dry fitting without glue is fine.
If the products used are food safe plastic and/or safe for potable water there should be no issues with toxicity. If PVC is OK for your house pipes, it should be OK for your AP system. An important point to keep in mind is that
fish are very sensitive to toxic gick - much more sensitive then we are. For example, you can't use copper at all in AP systems because it will kill the fish where as we still use copper for potable water systems.
