Molly alkalinity buffer #1
I have 14 juvenile balloon mollies with their mother(they are old enough to not get terrorized by her)in a temporary 20gal. tank. I am moving them to a new 40gal. setup and I need a new alkalinity buffer since I am changing substrates from crushed coral to fluorite(for some java moss and vals). What would you guys recommend for a new buffer?

Hi and welcome,

Do you have an external filter on the tank they'e going in to?

If so, you can place crushed coral in the filter canister and it will buffer just as it previously did as a substrate.

Re: Molly alkalinity buffer #3
I don't have an external filter or but I have an internal one, specifically the Fluval U3 underwater filter. Great idea!

Re: Molly alkalinity buffer #4
...or at least I plan to get one for the new tank. Should I get that or a canister filter?

Re: Molly alkalinity buffer #5
Having used both, I'd plump for an external any day. They require less cleaning, although it's a bigger job when they are due, mainly as I clean all the pipe work at the same time and they give you loads of room to add extra media.

Not sure a little bag of coral shell would fit that well into the fluval as they seem to be quite streamlined.

Alternatively baggy up the buffer (end of a pop sock/pair of tights) and 'hide' behind strategically placed rock/wood. Not as effective TBH as in the filter where water is pushed through it but an LFS near me does this on tanks where required.
Please fill in your personal profile if you are posti
