FAQ: Can I use Seachem PolyGuard™ together with _______?

Another Company's product

We are not aware of any toxic interactions with other current major medications or products on the market, but we very strongly recommend against using other medications or treatments in conjunction with PolyGuard™, as this is very likely to stress the fish.  We also can't 100% guarantee any product that's not our own, but here's a few quick rules for using PolyGuard™ if you usually use a different brand for aquarium maintenance:

1. Avoid using products that overlap in function.  PolyGuard™ is sufficient to clear out most external infections all on its own; it is not necessary to use multiple medications at the same time, and will likely be quite stressful to the fish.  If your fish has both a external and internal infection simultaneously, we'd recommend using a medicated food blend instead of mixing the second medication into the water.
   
   1. a. MetroPlex™ food blends clear out internal and external parasitic infections like ich, velvet, and hexamita. See the full instructions HERE.
   2.  b. KanaPlex™ food blends clear out internal and external bacterial infections like bloat, fin rot, and columnaris. See the full instructions HERE.
2. When in doubt, wait 72 hours. PolyGuard™ breaks down completely after 72 hours - if you need to dose another product and are concerned about possible product interactions, wait 72 hours and the PolyGuard™ should be completely exhausted.
3. Do not use chemical filter media.  Medias like carbon are capable of removing medications over time.  When using medications, it is best to remove all chemical filter media.  It is perfectly fine to leave the biological media as well as any sponges and pads in the filter though!

Seachem® Products

PolyGuard™ does not directly react (form a toxic chemical) with any of the other Seachem® products, but it is not recommended to use multiple medications or treatments at once if it is not absolutely necessary to treat multiple infections. For more information about combining medications, check out FAQ: Can I use Seachem medications together?

Also keep in mind that it is not recommended to make major alterations to water chemistry while using a medication, as this will likely stress the bacteria colonies.  Products like buffers and mineral additives can be used to make major alterations to water parameters, and while it is fine to use them in a tank being dosed with PolyGuard™, care should be taken not to alter water parameters too quickly or too drastically.
