My minimalistic 180g SPS tank

Have you seen any benefit to keeping low phosphate? Will all those tangs, you certainly can't grow any algae. My SPS colors and growth really perked up as soon as I got rid of the GFO and stopped checking my phosphate. I imagine I am around 0.2-0.5ppm, but I haven't checked in months.

No, I was trying to raise my phosphates but honestly completely forgot I had the GFO on. So now that is offline, going to keep feeding the same and hopefully I can slowly raise phosphates to run 0.05-0.1 at the highest. Why do you think yours is so high?
 
a flame hawk or longnose would work completely fine in your tank. another great option is the mystery wrasse. rugged enough to hold its own in your tank and has amazing color.

I keep a pretty detailed log in excel.

The last time I checked phosphate when not doing a phosphate RX/GFO regimen, it was at .23 ppm, but that was back in November. The last time I checked it all together was December 1st (0.02 ppm), but that was back when I was giving phosphate RX drops (about a few per night).

The last time I did anything to reduce phosphate was 10 drops of phosphate RX on 1/15/17 7:30 PM. I have no algae in my tank and I have never had my acropora so colorful. Even my vivid rainbow delight is starting to get some blue/green to replace the brown. I think the growth on my bushier acros might be a little slower than some tanks that keep a phosphate regimen, but my stags are noticeably growing every couple of days.

Yup that is exactly why I took the GFO offline, I went back to look at the logs of my old build before I moved the tank in December when I had the healthiest acros I have ever had in my years reefing and I was just running cheato and a skimmer so I am just going back to the basics.

Thank you!

I was thinking about getting a mystery wrasse but havent ever seen one in person at the LFS and I dont usually buy a fish unless I have seen one in person. I will have to keep my eye out for one.
 
Cody, those last frags shots looked really good!
What about a pair of genicanthus angels?

Thanks Matt! Everything is looking very good lately (knock on wood) and I will have to take some new pictures this week, if everything continues to go well over the next couple weeks and colors improve I will probably add more frags.

I am not sure what those angels are, will have to look into them. I am scared to add angels in here till the frags are bigger. I had a Regal and Emporer but both ended up picking at the corals so I had to sell the Regal and I moved the Emporer to a 300 gallon fowlr I have running, that I am about to add a coral cat shark and stingray too.
 
so I really need to add more fish but not sure what to do. I may just add 6 blue chromis and hope they make it through.

I feed 4-5 times a day and my phosphates ppb just read 0. All I have running is the skimmer and a ball of cheato. I just took the skimmer offline as I am noticing alk burn again when my alk is at 8, I am lowering my alk to 7-7.5 since I have such a hard time getting phosphates which I cant believe with all the fish I have and how much I feed.

I ran out of acropower about a month ago and I didnt get new stuff but now I just ordered a gallon and I am going to dose 36ml of it a day and test phosphates and nitrates everyday till I get a level of 0.05 phosphates and nitrates above 2 but less then 10. I also got new filters since tds was 1, now it is 0. The coraline is growing great on the rocks and back wall, etc. Some of the SPS have great PE but others just look like theyre burning from the tips again. Really struggling with this tank move but luckily I don't have a ton invested in SPS anymore, for once actually have more invested in the fish haha
 
What are you feeding? If your not already then feed pellets to increase the phosphate. Have you considered dosing phosphate as well?

That also seems like an awful lot of acropower to be dosing not to mention the cost, consider dosing nitrate instead with just a little acropower. Just be careful your phosphate doesn't bottom out even more though.

What other filtration do you have besides skimmer and cheato? do you have a tonne of siporax or matrix etc? you may look to remove some to help your levels rise if your system is that efficient.

Feeding 2 cubes at night and flakes 3 times during the day when im at work via an auto feeder. The acropower isnt expensives as 36ml a day will last me over 3 months and its only $60 for a gallon, people pay a ton more then that on supplements. I dont wanna dose phosphates or nitrates yet, looking to do it more natural ways first,

I have no other filtration
 
I'm guessing your low po4 is to blame for the tips. I have it now also and have seen the same effect in the past.

Exactly what I am thinking but I don't know how the hell I have such low p04, I am going to leave the skimmer off for awhile and go from there. Crazy to think I can have 4 tangs, 5 lyre tails, 1 chromis, 4 wrasses, 2 clownfish, 1 diamond goby, feed 4-5 times a day and still have 0 ppb on the URL ( I ran it twice too, 30 minutes apart). I think I am going to add 5-6 more blue chromis
 
I'd feed some more and leave your skimmer on. It provides a large amount of oxygen to your system. Brs reef chilli is full of po4.

The genicanthus family of angels are all planktivors and will not touch your corals. They are also dwarf angels so don't get nearly as large as most angels. They are beautiful, do amazing in pairs or harems, eat anything you add to the tank and are pretty non aggressive. Pretty much the perfect reef fish, imo..
 
Might see some aggression between the anthias and the Genicanthus angels, but they are definitely a fish to consider.

Might also consider blue throat triggers or another Xanthichthys species of trigger. These triggers are generally considered reef safe and are open water swimmers and feeders.

I am adding 6 green chromis too, hopefully they will make it and not kill eachother. I will leave the skimmer on and with the acropower see how it does. I never used brs reef chilli but may need to check it out

I will need to look into these, thanks!

I always considered a trigger but thought they wouldnt do good in my tank, not sure why I thought that but I will have to check them out.
