What’s in the small blue plastic chamber of a “big blue” canister normally?

You can have anything in a big blue as all the cartridges come in big blue sizes, from water softeners to carbon blocks, chloromine removers and sediment filters.
If you look at big blues for sale they'll have whatever cartridge in them that suits the target market for that particular retailer.

I understood the name big blue just applied to the multi pod systems with canisters that are 10"x4.25" or 20"x4.5 inch as pictured in post one of this thread.
Didn't realise the name extended to other types of housing.

Ah I see what you mean. The big blue canister is the pre filter which I guess contains a replaceable sediment cartridge, preventing the carbon block in the dechlorinator bottle from getting blocked up.
But I don't think the blue canister is a big blue, it's a standard sized pod from what I can make out.
Think I've got that right but correct me if otherwise.
EDIT: just discovered that other koi outlets call any dechlorinator that is big and blue a big blue, talk about confusing!
The original big blues, also known as Jumbo's, are these and come in 10" or 20" with replaceable cartridges, usually sediment, then GAC, then Carbon block, and essentially do the same thing as yours.

Edited my post above Tom.
Yes they do the same thing, bit like comparing Firefox with chrome.... One is customisable and the other just works!

Hi all,
I need some help please, I've just purchased a water purifier from Caostal Koi https://www.coastal-koi.com/shopping.php?class_id=73 the 24" version, I've tested my water pre and post filter and my PH has gone from 7.5 to over 9, I'm totally baffled and the dealer can't add any reasoning for this happening.

My Water parameters from the waterboard are:

Any ideas why I would get this result?
Thanks
Mark.

Dechlorinated water has a higher PH than water straight out of the tap. It proves the dechlorinator is working.
I have no idea on the science behind that, only that my PH is also higher after the dechlorinator than it is before.
I'd also say your PH is closer to 8.5 than 9 in that picture. 9 reads really dark blue on that test kit.

Thanks RS
Is this going to cause me an issue? as I've never had PH that high before.
I did split the system and after the prefilter to test and the ph dropped to 7.0, so agree it's the carbon increasing it. Is there a system which maintains the PH, or will all similar systems provide the same result?
Regards.

All the same as far as I know/understand, unless you start delving into RO water.
The PH on the pond should find it's own level and stay there with just small variations dependent on plant/algae growth etc.
I don't think your PH is 9 though. If you tested with a different kit that measures in smaller increments I suspect your PH would be closer to 8.4 or 8.5 which is in the higher the of the scale for koi but they'll thrive fine in it.
The advantage of a high PH is that you've a larger margin for error against a PH crash if your KH is low.
Manky Sanke is the real water expert around here, so be aware that the info I've written is either from personal experience or from what I've learned from Manky.

Yep, easy peasy and you need to seriously consider whether you should change your dealer if they don't understand pH which is the most important parameter in a koi pond:
When chlorine or chloramine is added to water, it makes an acid (hypochlorous acid) which obviously lowers the pH value you measure straight from the tap.
When you dechlorinate water, whether by a purifier, sodium thiosulphate or proprietary dechlorinator, you are removing the acid and the pH value goes back up to the original value it had before the supplier added the chlorine/chloramine.

Good read on this. Living in Surrey the water is hard and dries your skin very easily. The Mrs complains of it too.
On a 10,000l pond fill - 1 litre of blagdon fresh start is needed £16. So I'm sort of tempted.. but at the sametime I could happily run a 10" for the 10,000 litre fill over a week at the slow rate needed with the knowledge that there's less 'other stuff' in the water.
I suspect if I get one.. and she tries the water from it to drink first.. we may end up with one for drinking water rather than bottled water she drinks now.

A lot of info is available in this thread, if I've missed the required info I pre apologise.
I use a 4 stage 10" jumbo bb, it's does work, but recently it doesn't appear to last as long as it should. Apparently many people seem to be having excessive amounts of chlorine/chloramine added to the water supply so am looking for the correct way to remedy this issue.
1st off, is "Catalytic" carbon worth the extra cost?
Is it worth purchasing refillable cartridges and using catalytic carbon in the 4 stage or should I just add a 24/36 inch huge bottle thingy after the 4 stage?
Also what is the correct order to fill the 4 stages? Currently it's, prefilter/gac/cb/cb
If I do change to refillable Catalytic carbon, can it be prefilter/cc/cc/ccLast edited by kikokuryu John; 05-10-2020 at 08:05 PM.

Hi John,
That's the same order i have my cartridges in and believe it is correct. You want the pre filter first and the most sensitive one at highest risk of blocking up last.
Do you have a water meter attached prior to the 4 stage? Maybe you have simply used more water this year than normal.
Also possibly they added more chlorine etc this summer what with lock down and everyone buying pools etc and the resultant increase in water usage.
