Duncan help

[dcforester1]

My Duncans have been retracted for the last month. I have been battling cyano, and have had acoulpe of changes going on. They have been coming out alittle, but they were growing like crazy, and always extended. All my parm are in line, any ideas? I also have some Dendros that are acting the same way. They are not dead, but Im affraid thats how they are heading. Everything else in the tank is doing great. IDK what else to do. Anyone have any ideas? I also noticed some Acans I bought were not as fully extended as they were in the LFS. Obviously something is going on, but cant figure it out.

My parm are:

Phos is at 0
trates are at 0
alk7
calc is 440
mag is 1350
ph is 8.1

Thanks for any suggs

it may be a silly question but did you check ammonia and trite? i assume they would be at 0 but you never know. sometimes my acans will retract a little bit for a day or two then they will be fine.

Ya I did, I cant figure it out. Its obvious something is aggravating them all. I tried moving the Duncans, still nothing.
Thanks Derek

i am not saying this is definately it but maybe try doing a water change to replace trace elements that you might not be dosing. it could be that everyones advice to "don't dose what you can't test" for may be incorrect, because it seems that everything is fine judging by what you can test for.

stupid answer.... but are you feeding them?

i was thinking the same thing but wouldn't they be open if they needed feeding maybe. or are you saying that the damage might already be done?

Check your temp,just in case something went in a heater.
Also,although not extremely low the alk could be boosted some.I'd shoot more for 9-10 dkh and that will help any PH issues.

Try running some carbon...maybe interspecies chemical aggression?
