SPS RTN

[mutley29]

All my SPS are RTN'ing and i don't know why, all params are fine, phos 0 and have added nothing new to tank for at least 6 weeks, it's strange because my ricordia seem to be suffering too as do my hammers and torches to a lesser degree, everything else is fine, clams are happy as are my 2 RBTA's, i'm stumped, have been running carbon and phos ban 24/7 and changed out regularly, nothing seems to work.

 

just about to start a large water change 40% or so.

 

Anyone got any ideas?

I would frag the salvagable parts of the SPS that RTN has not reached yet ASAP. Through away the white skeleton. Basicaly it's a chain reaction some times w/ RTN where it jumps from coral to coral & removing the dead coral can help stop this chain reaction.

What is your DKH? (carbonate hardness - alkalinity)

I always start with that since it contrbutes to both RTN and colorloss.

A water change will dilute the problem for now.

chip do you mean too low or too high? were do you keep yours?

were do you keep yours?

I like to keep mine around 7/8 drops :D

Too low and you see RTN and colorloss

per minute? lol i forgot sorry

It depends on the test kit and what you are testing for.

I can't remember the name of the test kit I use but it comes in a blueish box.

I like around 4-5 meq/l (7-8 drops) or 10-11 dKH

is 15 dkh too high?

Is the sand binding (clumping together) in the tank?

Personally, I would try to lower it a bit through water exchanges.

What are you adding to get it that high?

[GaryL]

kalk reactor. ph stays round 8.0 - 8.4 i took it off line. i will start the h20 changes now. have 70g made up already.

What salt are you using? High levels of Mg can contribute to false high dKH readings. Thus, more water changes might contribute to the problem rather than resolving it.

 

Oh, if it's not broken, don't fix it. What makes you think 15dKH is bad? I personally would strive for 4meq/L, but if it's working for you, why "fix" it?
