DIY calcium dosing?

I've notice some of my plants new growth is curling, and from what I've read its probably because of a calcium deficiency. Is there any other way to dose it besides dry ferts? I know for shrimp they just wash an egg shell and toss it in there, but would that egg provide calcium to the water? Also read that snail shells slowly leach calcium, is thats true? If so would getting some assassin snail to free up some snail shells help? Or is none of this really enough and the only way is to just dose calcium?

I have a high lights, EI dosing, O+ root tabs, and DIY CO2 for a heavily planted dutch style 40b.

So why is it so unsuitable to just buy a GH booster from a fert distributor ?
GH boosters have the calcium in it. OR you can buy just the CaSO4 from them and get MGSO4 from the drug store and make your own GH booster so you don't get the K2SO4 that is normally mixed in to GH boosters.
Or you could buy calcium pills that are made for human consumption in the pharmacy dept. If using it for just adding calcium to the water just put one in the filter and check the leaves after a month or three weeks. Replace once a month(if it has all been used up/disappeared. Snails and shrimp like them however if that
is included in your reason for wanting them. If you don't have a gm scale then eyeball it to see that you are not doing more of it than the GH booster says to use.

The shortest distance between any two points is a straight line...in the opposite direction...

Holey rock? Is it of any use for calcium? I have hard water but my KH drops to 0 within a week.

Thanks! I didn't even think about calcium pills, might have some lying around. I could easily go buy the GH booster but I'm just really cheap, lol.

You can also use cuttlebone, pretty cheap over here it's less than two dollars a piece, three for five bucks.
It's slow release and unquantifiable though.
I would break it up into smaller pieces to increase surface area for dissolution and put it straight into the tank in a good flow spot or in the filter. I've done both ways, it takes a few days to sink.

PS it adds carbonates too, and some magnesium

Could it possibly be anything else?

I've personally never seen a truly calcium deficient aquatic plant. Sure it can happen but it's rare.

If you're dosing EI properly then we can basically eliminate deficiencies. Btw, part of EI is GH booster. To eliminate it you have to know your Calcium and Magnesium levels.

DIY CO2... Ever think about a CO2 deficiency? DIY CO2 is nowhere near stable. Plants develop enzymes based on CO2 levels. When CO2 is unstable the plant is basically confused and may or may not produce enough. This leads to deficiencies.

I would venture a guess that if you eliminated the DIY CO2 and instead dosed Excel you would see more growth as well as normal new growth. Can you tell I'm not a fan of DIY CO2? lol

My drop checker shows that my co2 levels are good. And i still dose a capfull of excel a day. There is only one plant that is curling the rest are growing just fine. I do plan to get presurezied co2 but all my walking around money is being spent on shrimpin.

I'll try the cuttlebone in the tank, maybe my shrimp will enjoy grazing on it as well.
