Just want to make a special announcement about the after-presentation activities:
All members are encouraged to bring some frags to swap. This is always pretty fun during meetings and we missed out on it at the last one. (At least theClark came through with some complimentary raffle prizes). Reach out to people, advertise what you're bringing/looking for, and don't forget the coolers.
We will also be having some fun raffle prizes. Gift certificates for coral, supplements, and local stores will abound!! That means you better bring some cash. And by some I mean A LOT. :cool:
Great post! I'm glad someone moved on the units. I am still considering the older 40 if I can find one since the price has dropped so much on them. The black units definitely look sleek, though.
SPS in general will benefit from higher lighting. The trick is just making sure that the corals get acclimated properly. Obviously even the most acclimated corals can be washed out with too much light so you may need to adjust based on light intensity and distance from the water.
Ok gang, I totally dropped the ball on this one. Let's resurrect it for another week and we'll vote for the pictures at the end of this month (20th) Post away! Remember, each person can post two pictures. Thanks all!
Great work team! This is such a heart warming thing to participate in as an organization. Special thanks to Jeremy (theClark) for his motivation and facilitation. Thanks Kevin for your help!
I think you're missing my point. This IS two part. Two part means that you are dosing separate alkalinity and calcium supplements. Technically there's three parts including magnesium, but the process is just called two part dosing. There are several different ways to dose alkalinity and calcium, the way we are discussing is just one. Buying the products from the store is another.
This is two part. It's just using a DIY recipe instead of buying store products. Google Randy's Two part recipe and you'll find it. It takes a bit of reading to properly understand initially, but in the end, it's quite simple.
Dow flake is calcium chloride dihydrate, which requires 2.5 cups per gallon. Prestone Driveway Heat is calcium chloride monohydrate which has less water (more concentrated). Therefore it would only require 2 cups per gallon.
I wouldn't worry about impurities too much because the product is straight calcium chloride. Not to mention the product has been used extensively for years and there is yet to be any significant reasons to discredit it.
I use baking soda for alk (get a big bag from Costco for like 8 bucks). I then use Prestone Driveway Heat for calcium (get it at Auto Zone for cheap). Then for magnesium I use epsom salt and magnesium chloride from Dead sea works (the latter has since gone up in price). Basically I just do the Randy recipe as far as DIY.
