RO/DI Questions
Evening stick heads! Looking for some second opinions in light of the situation im in. So the story goes I've been struggling since the start with most all acropora and just recently I've seen a decline in full tank health as a whole. Lately I've been upping water changes to be on top of weekly maintainance and this is when I observe a drastic change in coloration and tissue health.
Parameters are as follows. Salinity - 1.026 Temp - Always between 78.0 and 79.0 F Alk - 8q+ dkh Cal - 470 Nitrate - 25 Phos - .17 Running carbon in TLF reactor Reverse Photo fuge Recently I've added a calcium reactor to the system and its kept alk stable to the point of 7.5 to 8.5 I have a hunch that it may be my source water leaching chloramines even through the 4 stage RODI system and chloramine block. Has anyone ever ran into this problem? Sent from my SM-G960U using Tapatalk |

I run a 7 stage system and I still get worried about stuff getting through. I just sent in an ATI ICP test, which also tests your RO DI water. $45 well doesn't for peace of mind.

A few things can cause that, low iodine being one, but it's well worth the money getting an ICP test. Like I mentioned, ATI tests your RO DI as well. I've used Triton in the past, but they don't offer the RO test.

You can just buy a test kit and do it your self. Bulk Reef Supply sells them.

Disclaimer: My water doesn't have chloramines so I've never used any of these products, I'm just going by what I've read. I do put a few drops of Seachem's Prime in my RO water just in case it has any chlorine still in it. https://www.bulkreefsupply.com/insta...s-lamotte.html |

Would it actually help to catch whatever chloramines may make it through the RO/DI system if you add an additional carbon block as an additional final stage?

On another note, nitrate and phosphates are a bit high. My SPS freak out if nitrates are above 10 and phosphates above .1. Plus algae starts to show up.
Ideally, I am for nitrates between 2 and 5, and phosphates around .03

I run a 7 stage system and it looks like it takes every thing out

25 nitrate and .17 phosphate is too high Those numbers posted above are right on point! |
