RTN outbreak in progress. what next?

[mogulski]

I initally did maybe a 30-40% WC now i've been doing small, like 8 gals on a 120 volume system every five days. I fragged off a lot to save what i could, been skimming and running lots of carbon.
what next?
I have no idea what caused it. maybe my tank got to warm before i installed my chiller, my salinity may have been a little low as well. i recently installed a new HQI lamp, but did raise teh pendant to allow for par differences
all params have been in check for some time. how long befopre i can start rebuiling? oh and does anyone have some frags as i lost at least half of my SPS

You just gave 3 potential reasons for it. And then contradicted them with the last statement.

What has your alk been? How often do you check it?

alk registered:
9.3 march 14
9.0 april 21
8.0 may 26
8.4 june 25

sounds like to much change in a short period of time


alk looks fine

didnt read the post right.....sorry. alk sounds good...i agree.

i would think that flucuating 1 dKH around a 30 day period wouldn't be catastrophic??
in foresight, how long should things be super stable before i start to reup on SPS.
Also, i have about a 1 1/2 - 2" sand bed. should that be cause for alarm. also my Mg is ~990. i know that's low, but i haven't heard of low Mg causing RTN.
As always, thanks once again RC crew

too much water changes too quickly can very well add to your trouble...you do let the salt circulate/mix with a pump for at least 24 hours before adding?


Get a refractometer..its worth it...it seems these handheld hydrometers are way off...many say their hydro said .023, when checking on a refracto it measures like .029 in reality...just a thought....

could be a # of things....too many varibles to give an answer just off the info you gave us...got any more info that might help?

Frags ya I got frags...pm me....

yes and yes.
i let the water circulate in a rubbermaid brute 32 gal container at least overnight. before i even start filling w/ RO/DI i wash it out to prevent contamination of tds.
I also have a refractometer that i just recallibrated the other day with RO/DI.
