Hows the Alk situation today?

Hey mate. It's 6.7 dkh and cal is 375 so we're finally getting somewhere!  Still not a clue why consumption has increased so much. Cal used to be dead stable at 18ml a day,  now I'm putting in 72ml a day and it's only climbing very slowly.

The other weird thing is the water keeps going yellow. No matter how much carbon I put in,  a couple of days later it's yellow again. Not sure if it's algae or what.  It almost seems to be going through the cycle/uglies again,  but no sign of ammonia.

Anyway my house is 99% finished so we are moving back in on Friday,  and the new tank should be arriving this weekend (fingers crossed H2O Aquatics don't let me down...)  can't wait now!   8D

Just need to break the news to my mum gently that the 85L will be staying at her house a little longer while I cycle the new one!

Just to bring this to a close...
I had a few problems with this tank towards the end. Really odd usage of 2 part, weird colour loss/changes in corals, lots of CUC deaths.

I put these down to general lack of maintenance as I couldn't get to the tank more than once a week or so.

Today I was cleaning the equipment from it and found cracks in the impeller of my Tunze 6040.  Guess I must have dropped it, but I don't remember ever doing that 🤷‍♂️

Not sure if it was the cause of the problems but I guess it wouldn't have helped.  Possibly also explains why my poly filter pads would sometimes go odd colours! 🤦‍♂️

Being a Tunze fan now, I'm surprised that that had happened.
Don't discount calcium as once inside a fissure it will build up and split the magnet, much the same way rocks crack when ice is formed in fissures.
On the good side, I bet that those impellers are readily available and will be for some time to come-that's what you get with a german engineered product. I know I can get parts for a GRohe tap/shower valve at least twenty years down the line.
Also nice to see nails not bitten to within an inch of their lives!

Thanks:

Thanks, yeah tunze is great for spares, I've already got one on order 😎 I'm not worried about the quality at all... This is almost certainly something I've caused.

calcium is good thinking! Bit of a 💡moment when I read that as I had a huge problem with it precipitating out of the water a while back. Wouldn't surprise me if that's the cause as it was all over the equipment in the tank.

Quite interesting as well, I just checked my other pumps and found two others have cracked impellers (but the plastic not the magnet).    Possibly explains why they kept running backwards! 😁
