I am not trying to defend the lanthanum usage, but I am also not super against it. But the number 11 should be ug/L, so actually not that crazy high, and potentially still acceptable, unless you have some of those rather sensitive tang types (e.g., acantharus type I believe).

Some more water chemistry details re chloramine levels. I am still working on a fix with Chris / Airwaterice.com. Relationship between pH and chloramine levels Chloramine (a compound of chlorine and ammonia) stability and presence are influenced by pH because the ratio of ammonia (NH₃) to...

I wonder if we would still be BAR members if we did.

Taking pictures (or videos) with these standard microscopes drove me nuts when I had dinos and wanted to share how my sandbed looks like with others. I admire everyone’s patience doing this. I went with a (slightly) different setup from Bresser with their digital camera / MikroOkular HD camera...

In fact a great idea to offer free memberships to young adults from e.g. 16-21.

Has anyone who uses this Pentek cartridge actually tested if it did remove all the chloramine?

I understand that sentiment. I am currently trying to learn much more about that than I ever wanted to know....

The 2024 EBMUD report shows that chloramine levels can go up to 3.8 ppm.

Its not necessarily a tank topic, more an equipment concern - I am not seeing a positve test on my post DI water, only post RO. I am using the test kit below, but the fact that an 11 USD test decides that I should be buy a 300 USD+ filter concerns me. So as mentioned above, if anyone knows a...

I turned back to being a meat eater haha—just joking. The vouchers are still available; I’m simply waiting for the right moment to pull them out again :).

That was my question - good to know - not sure if as effective though, but I did not like the 20 inch size.

According to airwaterice.com aka Chris, my membranes (2) are already done, after 6 months, and post completing an RO evaluation tests which indicated that the rejection rate is only at 82%.

Certainly a monster price, but removing chloramine properly seems to bigger issue, so that folks are willing to pay that much money for it. I might end up buying such a thing if needed. Thanks for sharing.

We are / were massive lego fans, and still have quite a lot in the house (slowly phasing out). I do like almost all of their sets, specifically the bigger ones. However, this one does not look good. Almost bad, actually. Shocking, and I wonder who consulted them. The Petco-style treasure chest...

@ReyDeFarts - special shout-out to Andy for being so patient with all of my questions in the past few days. We agreed that I would reach out to Chris aka the H2O guru to get his thoughts on how this issue can be resolved. if anyone has a recommendation for another chloramine test, please let...

I wanted to tag on this topic here: https://www.bareefers.org/forum/threads/rodi-system-recommendations-and-considerations-and-which-ones-not-to-buy.38013/ But then I thought it might deserve its own thread. I am currently working on solving the following issue: I am testing positive for...

Thanks for sharing. I heard that this is a moonshiner thing to use CAC. I thought there was a difference between DOC and SAC? My SAC was between n.d and 0.4 previously, so not a problem I am trying to fix. But more surprisingly, Salem recommends in this article three times the amount of CAC...

The high quality pellets that Polyplab and Fauna sell are better IMO, same higher quality and break less. Potentially the same product that Erin recommended but I cannot confirm.

I am a fan of pelletized carbon such as the one you recommended. Would not buy any other at this point. Unfortunately, they do not seem to sell to individuals, and their online seller went out of business...:(.
