    3 stage cartridges due for replacement

    Hi All,

    the market is flooded with replacement cartridges, just wondering if anyone did any research on these to see if any were more superior than others? cannot see any carbon density data etc.....need to order a full set, any pointers / reccomendations / manufacturers would be appreciated... cheers Steve.

    I know Shosha koi have recently released some that are meant to work 7x as long as a normal cartridge https://shoshakoi.co.uk/shop/pumps-a...carbon-filter/

    I've used the fibre carbon filters, and don't rate them at all, they very quickly let chlorine past.
    for long lasting and value you can't beat catalytic carbon, either GAC or 1 micron chlorplus block,
    but the 1 micron blocks need a 5 micron prefilter and 5 micron carbon block before them or they block up real fast.
    the 10" jumbo have a decent amount of carbon and last a long time.

    RO Man does good quality chlorplus blocks, but customer service and delivery times are a bit hit and miss coming from northern ireland.
    but you can get a set of 3 standard 10" prefilter, carbon block and chlorplus for 25 P&P

    i rate the 10" BB jumbo blocks (4.5" diameter) over the standard 10" (2.5" diameter) they are twice the price (55), but contain 4 times the volume of carbon

    Is this better than dropping in sodium thiosulphate every water change?

    hi Shumboom,
    ST each day will help eradicate Chlorine but it wont deal with sediment and metals etc that is in your tap water, a three stage 10" or 20" in line filter is an option for you to run your trickle in through to manage/reduce the levels, when i test for chlorine i have yet to find any using this, also for belt and braces once a week i give the pond a squirt of pre made ST solution just to be sure.
    You will be shocked at the state of the sediment filter when you remove it after a few months, it goes in white and comes out brown.

    why is it noisey?
    is the mains stop tap not fully open?

    i use a 3/8" solenoid hooked up to a timer for dechlorinated water to replace the water lost by recycle RO.

    but i think i know the garden hose timers your on about.
    should work just fine, but i have no experience of them mate

    I just rembered being round a mates house and his missus ran a tap and the noise was ridiculous...
    I quickly worked out the mains stop cock under thew sink was less than half open causing a restriction and causing excessive noise.
    he was chuffed i sorted it... it had been making the noise for years lol!

    I never leave stop cocks open to their fullest extent because I've found that they are more likely to stick in that position. I open them fully then back them off a little which makes no perceptible difference to the flow or noise, maybe that was what the last person did to yours.

    I've always used these which in this listing are 10" jumbo.

    Good value, good service from the supplier, no complaints at all.

    To see how long they are quoted to last and what flow rates you can put through them, check out the 2nd post in this thread:
