Weekly dosing

[cable guy]

So I have a 20 gallon reef tank, I have Zoa’s, mushrooms, frogspawn, hammers , wondering if there is a weekly Aio additive I can add for my coral’s to keep the elements and so forth in check? I do weekly water changes, was wondering if anyone added additives to there water top off water or if it’s even possible so when it tops off my water it adds nutrients for coral..

I dose seachem reef fusion 1 and 2 for calcium and alkalinity respectively, as well as aquavitro ions for magnesium. I'm also running a 20 gallon reef that has a duncan coral, lobophyllia, and a few softies

So first off you need to determine if your levels are dropping with weekly water changes and by how much! That will give you a baseline idea of if you need to be supplementing or not. Chances are with weekly water changes and a lite coral load it’s not dropping by much. However the only way to know is to test it daily and get your readings. Then that can help determine how much it’s dropping so you’ll know how much to supplement.

Start checking alkalinity and calcium.

Trace elements I wouldn’t worry about since it’s a lite load and you’re doing weekly water changes.

Find a good salt brand that matches the levels you want to keep and that also has trace elements in it.

There are additives like Kalkwasser that can be added to your fresh res ato.

However let’s first determine if this is even necessary.

As mentioned, the way to *know* that you *need* to dose is by testing your water, paying particular attention to alkalinity (first, in my humble opinion) and calcium.

That said, for a 20 gallon tank and the corals you've listed, just using a decent salt mix, and performing regular, partial water changes should maintain your levels just fine

You really don't have to think about dosing until you have a tank of growing stoney corals and/or coralline algae that are using up these elements.

If you find that indeed you do need to dose to offset what your water changes replace, take a look at Tropic Marin's All For Reef, which is a simple way to dose the primary elements for coral health:


Best of luck!
