I also have a litermeter 3. I absolutely love it. Very easy to dial in and get your parameters spot on. I've had mine for 2 years and it hasnt missed a beat.
Which test kits is everyone using?
3 years ago when I started out I got Salifert but had a lot of trouble with the Salifert KH test kit. The kit would read a much higher KH level than was actually in the tank and I subsequently lost a few corals. I then switched to API and Elos which both seem to be pretty good. I prefer the Elos kits but they are pretty expensive. My Elos test kits are about to run out and I'm thinking about using API exclusively simply because they are a lot cheaper. What do you think of the API kits? And also, has anyone tried the new Hanna digital Phosphate tester? Looks pretty good for the money.
If you are retroing lights into a canopy it's a good Idea to use a couple of computer case fans to cool the canopy. I use two 12volt 120mm fans and a radioshack 12volt transformer. It works well and doesn't cost too much.
I'm talking about Rod's food
So far I've tried Upscales, Rosecity ( who even have a Rods food sticker on their fridge door, but no longer carry it), Soutas, Seahorse aquariums, and Salt water fantaseas. No luck with any of them. I used to buy it from Waves. :(
