Some SPS not doing well

[kratosxxl]

Folks my ALk started to go down ? do i dose just alk to keep it in range or what ?

Thank you for the reply, I really appreciate it!

I’ve added another wavemaker for extra flow in addition to my two XF350s.

Sounds like it should be an improvement.

You might start considering the long-term fate of the XF350's...I'd replace all three pumps with two that could do the job. No rush though!

I’ll try removing the fleece rollers, but I have 14 fish, including three tangs that are 4–5 inches, and they produce a lot of waste! Would you recommend using filter floss and replacing it once a week, or running no mechanical filtration at all?

Poop is even better coral food than detritus. Let it fly! ;)

The improved flow should make all the difference.

I also noticed some residue on the bottom of my sump that looked like dusty sand. I vacuumed it all out, but as you suggested, I siphoned the water through a filter and returned it to the sump without doing a water change.

You could try palcing a small powerhead in the sump to keep it from collecting there. I did that with my previous system that had a sump.

I completely agree that the tank is still too new to have stable conditions for SPS corals. I thought all the gadgets would help me get there faster, but apparently not!

At the beginning it does pay to keep it simple. You might find that as the tank matures you decide you want to add more tech, but then you'll have a lot more experience to base that on.

If you haven't already read @Randy Holmes-Farley 's articles about calcium and alkalinity, hit pause on everything else until you do. ;) In particular, this is a good one to start with:

Don't stop there though. Read on!

There are a lot of ways to run a successful reef tank. Given where you phosphate and nitrate levels are in the first post, I wouldn’t take your filter roller or other filtration equipment offline. I don’t see any reason why you would need to do so unless you are dealing with borrowed out nutrients.

Funny that you mentioned it because Hydros replied back to me that they are NOT officially supporting XF350 CLoud edition lol
What would you recommend ? MP40 ? 2 of them maybe ?

Small update guys. Things are getting from bad to worst more stuff is dying not really sure what to do i guess ill just lose all sps untill something.
Still waiting for ati icp to arrive but by the time i get results back all of them will be probably gone.water change maybe ? Not doing anything looks like not working :)

 

[kratosxxl]

Btw 4 out of 5 dead corals are from same supplier. 2 big ones had some tissue loss when i bought them. Im a hallucinating or it can be related ?

 

[kratosxxl]

This 2 i got from someone else they dont look bad to me. Or they are next in the line ?

In this kind of circumstance: First time tank, only 3 months old, started with mostly dry rock, and lots of “stuff” going on, I assume the primary issue is with you still learning how to keep a stable reef. We’ve all been there at some point so just stick to it and find ways to improve your husbandry. Eventually the tank will mature and stabilize.

A good sign that your tank is ready for SPS is when you see coraline growing all over your rock work (ie, multiple locations in your tank and with sufficient quantity not just tiny specks). Once that happens, wait a few months and then you should be ready to try some SPS.

Notcthet it makes much difference but i did started with like 80lb livecrock and 50 dry. Dry arecthe shelf ones.

The live rock was from an LFS who had it in their system, sitting in circulating saltwater for some period of time? If so that will help speed up tank maturity but the dry rock your coral are on look very new so will require some time to mature.
