I suppose I have been lacking in updates so here is the current state.
I have been trying to stabilize the tank after I had a setback. Everything was going great and I had a number of SPS growing great. I was tracking ALK an Calcium and was seeing my ALK continue to decline yet my Calcium was remaining stable and no real change in my PH. I decided to start dosing Soda Ash. I started with what I thought was a small dosage and over a few weeks my ALK was slowly moving up (9 DKH) and I thought I was doing great.
I had everything setup for my vacation including I moved to an external ATO to get rid of the ATO under the sump and more importantly I moved the ATO pump into a 40G Brute can for my vacation. After the vacation I replaced the Brute with a 5 gallon container and it resides in a black cabinet next to my tank. The ATO is working great and I appreciate the extra space under the tank. I also redid the UV and Fuge light placement. I am much happier with the current setup than my last attempt.
When I left for vacation I cut the Soda Ash dosing 1/2 but at the same time I stopped dosing Nitrate an Chaeto grow. If you recall when I started this build I knew I had a long vacation coming up in a few months so I opted to not run a skimmer and went with as big of a fuge as I could fit in my sump. I still plan to run without a skimmer but I am adding a reef-mat 1200.
I ordered a Reefmat as soon as my LFS would allow pre-order. I planned to have it ready to install as soon as I returned from vacation. My LFS contacted me to tell me it shipped and would be arriving either the day before, or the day of my departure. I stopped in the day before my departure and they said it didn't arrive but they expected it the next day. I told them I would be gone for 12 days but would be back on a specific calendar day to pick it up. I watched them write the comments and date in their special order book.
Jump ahead and I return from vacation and I stopped by to pick up the Reefmat 1200. I asked for it and they said "I think we sold that". I'm not going to get into all the details because it is a long story. The short version is I have one on order again, but you probably know they are all backordered.
I also have a small leak in my plumbing. The joint where the drain tube from the tank joins the down tube in the sump is leaking. I contacted Red Sea and I have a replacement for both pipes as well as I have bout the main connection fitting and a gate valve to replace the Red Sea valve with a new downpipe. I'm going to go with that route first and if that doesn't work I have the new Red Sea downpipe in reserve. That entire leak repair is on hold since I have to cut my downpipe to install the Reefmat. I zip tied a silicon cooking mat in place to funnel the drip into the sump so I can let it leak as long as needed. I do hope to fix it soon though!
I also redid the electronic side of the stand to clean up all the controllers and cords and such.
As for the tank itself all my fish, crabs, snails looked great. My ATO still had water left in it and my plan feeder worked great. Not as good for corals. All of my SPS had started bleaching and a torch had dropped a head and the other did not look so great. I would also note that a plate coral was starting to bleach as well.
I started mixing water for a water change and tested parameters before hand. Nitrate and Phosphate had been pretty high but not alarming. ALK was very high. It was over 14-15 if I recall correctly. Everything else was stable and nothing that concerned me.
I added another hour to my fuge lights and started to dose chaeto grow again. I had also decided that I didn't want to grow Ulva in my fuge any longer so at the same time as the 1st water change I pulled the Ulva out of the fuge and am now only growing Chaeto, Red Ogo and Dragons Breath.
From that point to now I have my nitrates/phosphates stabilized and where I want them but I cannot stabilize my ALK. I will bring it down with a water change but it keeps increasing again. I did a water change yesterday and tested the water this morning. Here is my current parameters.
RedSea
Nitrate: 2 ppm
Phosphate: .04 ppm
Hannah
Calcium: 419 ppm
ALK: 12.5 dKH
Salinity: 1.026 SG
Salifert
Mag: 1335 pm
RoboTank Probe
PH: 7.97
Prior to the water change the ALK was 13.3. At this point I am tired of dumping pounds and pounds of salt through water changes trying to resolve the ALK and I plan to start adding Muriatic Acid trying to see if I can find a balance that isn't going to throw my PH out of wack. I would like to get to dosing lime water and bring PH up that way but I can't do that with my ALK issue.
I am using Fritz Blue Box salt and I tested the batch of water I did a water change yesterday with. It came in at 7.9 dKH. I don't think i could find any other salt that would be a better option. I have put the plate coral in a frag tank and in my frag tank I have a frag of most of the other SPS in my DT so I am leaving them in place trying to bring them back. 2 appear to be coming back well, 2 are completely gone and 1 is trying to figure out if it is going to make it.
Livestock is doing great in the tank otherwise. Currently in the DT I have:
Labout's Fairy Wrasse
Blue Head Fairy Wrasse
2x Banded Zebra Goby
2x Watchman Goby
1 Clown
1 Tailspot Blenny
1 Yellow Tang
1 Mandarin
In QT I have
1 Two Spot Bristletooth Tang
1 White Tail Bristeltooth Tang
1 Royal gamma
1 Square Side Anthias
1 Green Chromis
In Hospital tank I have
1 Mandarin
I'm not sure yet if he is going to pull through. I'll probably post more info about his story if he makes it. The short version is a delayed UPS shipment left him with severe Ammonia burn and at this time his tail has completely dropped off. I found him after he vanished in my tank for 4 days and he was pretty lifeless. He is now moving around again but I have yet to see him feed.
I have also built a water changing station so I now can change my water and I don't need to lug around any pails of fresh or discarded water. It is much nicer this way!
Photos. My DT is just waking up so most of the livestock is in the rocks.
