    Guide: Lanthanum Chloride dosing for Phosphate control

    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).

    Microscope for Dinos

    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...

    Challenges in removing chloramine in RODI setup

    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...

    Challenges in removing chloramine in RODI setup

    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.

    Lego tank.

    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...

    Activated carbon (GAC) quality differences

    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...

    Activated carbon (GAC) quality differences

    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.

    Activated carbon (GAC) quality differences

    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...:(.
