Giving up on SPS!

10 is too high if your level of nutrient is low. That will cause all sort of problem like RTN, STN etc..

Sweet spot is natural sea water, 7.5 to 8 is ideal.

Low nutrient is good for SPS but they do need food then. Especially if you have a weak light, no wonder they are dying in your tank.

with low nutrien you need a good light, good food on regular basis and around 8 kh, no higher.

People think that SPS only live from light alone but in nature there is tons of zooplankton. This is also why SPS grow much better and faster in a mature tank of at least a year old, because by that time zooplankton and all sort of larveas have started to colonize the aquarium.

I feed my SPS every other day with zooplankton food like Fauna marin, reefroid, coral frenzy and I feed Zeovit amino acid and coral vitalizer each day. This makes all the difference in growth and color.

And I thought low nutrient is preferred by SPS :|

Its so confusing!!!!

I read from a reliable source that on avg, dkH in NSW remains around 3.5meg/L (aprox. 10dKh)

Alongside, I do feed coral snow about twice a week.

Maybe the light and the nutrient is the issue. Whatever that is, SPS are just not worth it to me

It will be very hard with a small mixed tank.My tank is at least 90% acropora with softies and leathers but it's a 100 gallons,no carbon.Don't feed them anything but tons of light.Yeah..their boring and brown..i really hate this ugly one.

10 is fine, mine sits there often and I don't have any problems. I've run it regularly as high as 14. Again, no issues.

Even with low nutrient system?

Yes. I lost track for a few months and tested it at 12. Someone told me zeo systems do best at 7, but that's too low for my liking. 10 is low compared to what I've run in the past. I find colors are crisper at higher alk..

I have to admit, I run my tank at Alk 7 because the zeo guide says to run it there (I run a zeo tank as well) and my SPS growth is still nowhere near as good as it was when I ran a tank with Alk 10. I'm very tempted to try running it back at 10.

I did notice that too. When I wasn't dosing my alk would sit near 7 and growth was kinda slow. Then I started dosing and held alk at 9/10ish and growth was insane. Although I personally prefer to keep my alk at around 8/9. To me that's kinda the middle of the road.
