Maximus297759 Posted August 21, 2021 Share Posted August 21, 2021 (edited) So good to not use prime in water if I use 3 stage filter? 5 micron sediment, Granular Activated and Carbon 10 micron. I’ve seen video people have these on drip system. So I’m sure that’s safe but what about 75g change in 125g tank?

StevesFishTanks Posted August 21, 2021 Share Posted August 21, 2021 (edited) If you only have to remove chlorine and not chloramine its much simpler than what I use. You could likely use one carbon block at a lot faster flow rate and still be safe. I use several filters to break the chloramine up and remove chlorine and ammonia. I have an auto water change system that is controlled with a sprinkler timer and solenoid valves. Flow fixed at 0.5gpm I use 1 micron sediment for the first stage then the big cartridge The filter that does the bulk of the work is catalytic carbon and kdf85. I use the 20"x4.5" big blue type. https://amzn.to/2Ug5gWi https://amzn.to/3z5Otol https://docs.google.com/spreadsheets/d/1mXhJMY0nAtFoQ4Lrvd1DrhWizs-t4NCzuNBuFd3bCOk/edit?usp=sharing Edited August 21, 2021 by s1_ 1 Link to comment Share on other sites More sharing options...
CT_ Posted August 21, 2021 Share Posted August 21, 2021 Now that I have the coop test strips I've found my refrigerator's carbon block removes all the chlorine, or enough for me to not see it at least. if it's just chlorine in your water then an NSF42 filter is probably enough. 1 Link to comment Share on other sites More sharing options...
Maximus297759 Posted August 21, 2021 Author Share Posted August 21, 2021 (edited) I’ve been keeping fish off and on 40 years never checked chloramine because when I found out about it I had been keeping fish at least 5 years. So I figured they all be dead if I did have any dodged that bullet. So I guess use chlorine but going start calling them ever few months I guess they could switch over at any time. “Carnahan Aquifer. The City has ten wells that pull from this aquifer. As a final step, our water is chlorinated for disinfection purposes prior to sending it into the distribution system and into your home or business.” Edited August 21, 2021 by Maximus297759 Link to comment Share on other sites More sharing options...

They are hella value compared other 20 inch 4.5 size. And don’t have be changed near as often as the 10 inch ones. if works well I’ll add 3rd one prob best add another carbon block 5 micron or 1 micron?

Maximus297759 Posted August 27, 2021 Author Share Posted August 27, 2021 I went with those filters recommended they cheaper then the 3 stage 10 inch 2.5 that’s stupid. So I have 3 stage if count 40 micron spindown. 0 chlorine atm says they last 30k 60k gallons depending on your water. So question is how will I know when carbon is depleted? Will chlorine be in water? I’m sure my sediment filter will clog up I can change it. But how do you know carbon block want pull chlorine out?

StevesFishTanks Posted August 27, 2021 Share Posted August 27, 2021 I use this https://amzn.to/3zhb0yt It keeps track of gallons used. It also helps if you need to slow the flow rate to match the filters spec. You can decide to test water periodically or just commit to changing the filter at a set number of gallons.
