Thanks. Most of my SPS are from other local reefers. I bought a majority of them from Cedric's packages.
Thanks. The problematic wild colonies came from GO but it wasn't a pre-order. One of the colonies immediately changed from white to brown. Another was quite beautiful for a couple of months and then started developing STN. I have a 3rd one that has done great.
Last time I was at GO I bought some zoas and it had a small anemone that was purposefully placed on the rock. Luckily, I asked on the forum for an ID. It turns out that the anemone is was a Majano anemone, which is a terrible pest that is extremely difficult to eradicate after it gains a foothold in your tank. I nuked it before it had a chance to spread but after that experience, I'll never go back there.
In general, I would say that local frags are much more stable and suitable for beginners. I'm sure there are a lot of beginning reefers who go out and buy a bunch of wild colonies. Their tanks look great for about 1 month but then they have a full a brownout and quit the hobby. Wild colonies are not very forgiving and so I would recommend against them unless you know what you're doing.
Regarding the Apex controller, since I'm an American, it is much easier for me to get stuff from the States and a US warranty & 110V compatibility is desirable for me since most likely I will be eventually returning to the States. For Singaporeans, I would think long and hard about the delivery issues and warranty issues associated with buying something from the States. For my other tank (RSM), I've decided to DIY my own controller using an arduino board.
If you are using Vortech pumps and dimmable LEDs like I am, I think they are great. If you are not using them, then I would probably buy something else locally. In fact, I think a lot of controllers support dimmable LEDs and so I would say that the real benefit of the Apex is the Vortech controller. That being said, being able to tweak things like Vortech modes and LEDs is really a luxury instead of a necessity.
Unfortunately, there are no controllers on the market that will monitor the most important parameters for SPS: CA, KH, MG, Nitrate, & PO3. If you don't have good high quality test kits for these parameters, spend your money on the test kits and forget about controller. I think Salifert is a decent kit for the money but for some parameters like PO3, I really like the Hanna Checkers.
In my opinion, API kits are almost useless for SPS since they aren't that accurate and don't measure low levels of either Nitrate or Phosphate. I have two full sets of API test kits that I only ever use when cycling a tank because I haven't bothered buying other brands of ammonium and nitrite test kits since I rarely use them.
I would also buy an ATO long before buying a controller. ATOs are so critical for maintaining tank stability. It's difficult enough stabilizing CA & KH at a constant salinity. If you don't use an ATO and you're also chasing salinity, then just forget about keeping your other parameters stable.
