My leafs on my amazon are curling up..
Wondering if i need to add magnesium.

Another question only way to know my calcium and magnesium is with a tester right?

How do i add magnesium or calcium to my aquarium?

Using pfertz [m], [n], [p] & [k]
Dosing flourish iron, and flourish excel aswell.

as anotherm ember posted. its likely co2....

the nutrient tree falls as such
Light
^ ^
Co2
^ ^ ^
Fertilizers

so if u don't have enough co2 for the amount of light u have, u will have problems
from there if u do have enough co2 then fertilizers are an issue this includes magnesium
Ahhh! Co2! Idk how much more i can pump lol!
I got a 405, and a G3 plus a AC30 power head(getting replaced by a hydor 750 today) for flow...
Co2 checker is yellow at mid-day or an hour early.
And my bubble counter, well you cant count it... Its a stream lol.
My lights are a maxspect razor 160W.

Nah, they look fine... My 3 flying foxes swim around eatting... My 9" red belly stays in his corner and just chills like usual. With his random bursts of energy whn someone walks by begging for food.

While i wait for my gh/kh test kit i also ordered a fluval Q2 to oxygenate the water while lights are at 1% moon light... Probably going to have it run untill my "sun rise"

And for my lighting... Idk... EVERYTHING has exploaded in color and growth ever since i got these lights... 4 years an never seen such color and growth... Pearling to a hole new level aswell

Get a hold of your kH value. If the kH is high you don't have actual CO2 in your water. You will need to lower kH to have more CO2 available to your plants. You either lower kH or increase CO2 input.

Well... Got my kh/gh kits... Tested my water...

Montreal:
KH: 7
GH: 8

Aquarium (based on mid-day of co2)
GH: 9
KH: 6
PH: 6.4
Nitrate: 8...between 5 and 10
Phosphates: 0.5

How's the tests?
this is acceptable for most plants
some sensitive species will do better with lower KH.. but they will grow just fine in higher KH, just likely not to grow as fast, or as colorful
again ur plants should grow JUST FINE

So to lower kh... Peat or black water extract? I dont want to lower my ph though
I said what you can do to lower your kH. It doesn't mean you should do it. The kH range I mentioned is what I consider best for plants based on my own observation. It also doesn't mean your plants cannot grow in kH 8 :)

My plants grew fine in higher kH and gH than yours. Some of them like Vallisneria use kH as a source of Carbon and some do not like it at all as it will limit CO2. Tonina on the other hand prefers soft water with lots of CO2.

There's no short answer to all plants. You will need at some point to experiment and learn which are the values that yield the expected results.

Mg++ deficiency is a little more common than many assume.

It's one of two things: veining of leaves, common in Swords and in Anumbias, but few other species.

The other is a general color loss of greens and slower limited rate of growth.

Adding MgSO4 back will restore the green color very fast(it's the central atom in Chl a, b etc, other wise the molecule is grey in color). and should restore the veining issue in a few days.

I've had everything from 0.3 ppm in tap up to about 50ppm of Mg. In dense tanks where folks do not add any known source of Mg, it can and does happen, most often when folks assume their GH is a nice balanced ratio of Mg and Ca, sometimes it is all Ca++, but extremely rarely, it might be mostly Mg, I've never seen a tap like that yet but perhaps one does exists somewhere. GH measures both Ca and Mg, not both.
If you dose a known source of GH, say GH booster, which is about a 1:4 Mg/Ca, then you know you will not be limiting.

Or most add MgSO4 to their CMS mix for traces.
