Hi Colg,

I bought the Hyclor calcium Increaser from Bunnings, I can't attach pics! But the packet is 4kg with a light purple top & orange & light brown stripes thru it, does this sound like the right one?
It also feels like granules nor a powder?

Yep, that the one. As with all bulk calc, you will need to give it a good shake when you mix it but it dissolves well. Follow randies recipe (there is an Aussie version if you google it). I go slightly different in quantities 530g of calc to 4l of RO. Alk I use is the hylclor PH increased (soda ash / sodium carbonate) at a rate of 400g per 4L of RO.

Shouldn't be an issue with either of those Benny. Col, have you noticed the Hyclor Soda Ash leaves a brown residue after mixing? Something tells me they use a coating on the powder or the processing picks up unwanted components.

Soda Ash 99-100% Purity https://hyclor.com.au/wp-content/upload ... reaser.pdf
Calcium Increaser 100% Purity https://hyclor.com.au/wp-content/upload ... reaser.pdf

Bear in mind that a 1% impurity can still mean the addition of 1g for every 100g dosed and in an aquarium of 100L would add 10 mg/L or 10ppm of impurity into the system... if this was phosphate for example you can understand how product purity can impact the tank.

Thanks.

I wonder about the impurities in comparison to hobby supplied carbonate & calcium?

Would you use the hyclor cal & carbs John?

Col has been around for awhile so if he's had no issues using them then I don't believe you will either. If the impurity is testable or something that is biologically removed like nitrogen then this is not as bad an issue, but my concern would lie more with heavy metal accumulation. One reason I recommend large (or numerous small) water changes over a short period once a year to reset the system from unwanted and untestable accumulates from all the chemicals dosed in there. Freshwater planted folk use this for EI dosing which puts everything in surplus than resets it back to the start with large water changes.

I've only handled the carbonate source so I can't say for the calcium, but based on their SDS it's 100% anyway. My concern with the alk source was a brown residue, which was why I was asking Col on his experience with it.

I haven't done an ICP test to know what the impurities would be and at what levels unfortunately but I'd love to know myself!

Cheers,
John
