Long overdue update.
It's been a bit of a battle to figure out why my SPS were not happy, but I think I have it nailed down now.
First was the Red Bugs. They were retarding my corals, then balancing nutrients with NO3 and PO4 dosing. So;
Beat Red Bugs this year Feb/20 and no problems after. No signs of AEFW and no losses of any critters. I figure the bugs came in to my tank via snails or bottled copepods as I had added nothing else to my water for over 3 years.
Pre Red Bugs - look hard, they are there !!!
I started dosing NO3 and PO4 some time before last Thanksgiving/2019, but didn't get into it too heavily as it kept inducing diatom outbreaks, or at least what I thought were diatoms.
Anyway, I started regularly dosing NO3 and PO4 around March or so of this year, and lowered my kH from an average of 8-8.5 down to 7.5-7.7.
Since then I've finally started seeing some proper colors in my SPS, and no ill effects to the tank. The dosing also did not bring on the Cyano I dealt with later. I feel that was due to the nutrients being too low.
I've been twice-weekly testing/dosing NO3/PO4 keeping it just around 2-ish/0.06, but not exactly - just monitoring and dosing.
I ran some Chemiclean at the end of May/20. 2nd time in 8 years over 3 builds. I just gave up cleaning it out and dosed it. Tank looks better now and the slimy bacteria on my LR is going away. I was also hoping the erythromycin content would help with some slimy/tumerous-looking bacteria on my LR. It did and the goop is almost all gone.
My pods, brittle stars and snails are really digging the cleaner tank. Pods have rebounded great since the milbemycin treatment, and I haven't needed to dose anything to entice the pods to bounce back, aside from the usual frozen additives I use when the fish get their dinner; mysis/ocean plankton/chopped clams/krill/calanus/cyclopeeze/rotifers etc. Nothing phyto involved. Just good food and good lighting.
After the Chemiclean dose, I'm seeing some truer numbers with the big 3, potassium, and NO3/PO4.
I've been testing the latter 2 twice weekly and am seeing a final dosing strategy.
I'll start testing those once/week along with my other 4 tests and see how things go.
I'd like to get myself back to a point where I'm testing the big '4' (with K) weekly, and testing NO3 and PO4 bi-or monthly.
Currently I'm seeing daily/weekly usage of N and P and trying to find a solid weekly usage. After a couple of months of regular readings I may consider adding dosers. I have a couple BRS-style ones I can add to my controller. We'll see.
Starting to get some coralline on my weir teeth so I hope to see some on the LR someday, although I'm not looking forward to cleaning it from the overflow box later on.
It's been almost a year since I did this restart.
So ....
2019 September pic about 2 months post re-start with the then unknown red bugs.
Most recent pic. Forgive the lack of SPS pruning as I'm still deciding on how I want to let them grow. Plus I didn't get the angle right on the pic, so the growth doesn't look correct. Anyway, it is what it is.
I'm judging the growth based on what I've seen just in the last few months, which has been fairly significant compared to over the year. I'll need to get some better pics up soon to compare.
And I'll need to start posting some SPS closeups as the polyp extension post-red bug treatment is massive. Even my deepwater blue is completely 'fuzzy', and it's never been this active in the many years I've owned it. It was one of the first SPS pieces I bought back in June/2012. Yes, I've had this coral for 8 years !! but not this colony.
I lost it when a tank failed back in 2016, but I was lucky enough to buy a piece back from a local reefer friend after that re-start.
I can see it's polyps flutter as the MP10s create waves !!
Thanks for looking !!
