FAQ: Can I use Seachem Replenish™ together with ______?

Another Company's product

There are a lot of aquarium products on the market, and while most of them will work perfectly fine together in the aquarium, some will not.  We can't 100% guarantee any product that's not our own, but here's a few quick rules:

1. Avoid using products that overlap in function.  Either one works and so it's the one you should be using, both work and so it's a waste to use them both, or neither work and you should be looking for a third, better product.  In the case of Replenish™, using multiple mineral or salt supplements could result in a GH that is too high.
2. Research the products you use carefully.  Typically, if a product or medication is volatile enough to react with a mineral supplement, the company will mention it on the label or website, or you can call in to check.
3. When in doubt, wait a day.  While there should not be any interaction between the minerals in Replenish™ and another product, leaving 24 hours in between the doses will avoid possible fish stress from rapidly changing water parameters.

Seachem® Products

It's safe to use Replenish™ alongside any of the other Seachem® products that are recommended for freshwater systems.  That said, combining high levels of minerals with certain types of buffers can result in noticeable precipitation.  This precipitation is not harmful to fish, but can be unsightly until cleared away using fine filter media (see Clarity® for more info about clearing precipitation)

Among Seachem® products, there are several phosphate-based buffers that are recommended for freshwater community aquariums, but may cause noticeable precipitation if used in an exceptionally high-mineral tank (as can be attained using Replenish™).

Here's some Seachem® products that are phosphate-based buffers

Discus Buffer®	Betta Basics™	Acid Regulator™
Neutral Regulator®	Gold Basics™	Alkaline Regulator™

As previously mentioned, it is fine to use these products together, but high levels of either can result in nontoxic precipitation.  We recommend to dose in moderation to avoid this effect.
