Thanks of the info.

My 80 gallon has been set up and cycling for the last month. I have been watching pH, Ammonia, and Nitrates and it seems to be on the end of the cycle now. I did a 20% water change, and I tested for the first time yesterday Alkalinity, Calcium, and Magnesium and things seem off. The calcium and magnesium are very high. All other test came out ok. All test kits are new Salifert brand test kits. Salinity=1.24 pH= 8.2 Temp= 80 Nitrate= 15 ppm (pre water change) Ammonia= 0 ppm Alkalinity= 8 dKH Calcium=490 ppm Magnesium=1300 ppm I was wondering if this something I should be concerned about or if it is just because there is not much in the tank using the calcium and magnesium right now. Currently there is only a small mushroom rock, 3 small colt corals, and some green star polyps (have not opened) in the tank. They were all added Friday. All advice greatly appreciated.

Here are some photos of my tanks at school. This is the 80 I started with Untitled This is where it is at now. Untitled This is the 30 I am nursing back. There is normally a skirt around the bottom but it is in the laundry.

I think any of those would be great. The only thing I know I stress in my class is repeated trials so setting things up so that you have three setups or more of each condition (may-be dividing the tanks some how). I don't think all investigations need to be sexy they just have to follow the scientific method.

I teach out in Battle Ground at Chief Umtuch Middle. I will work on getting some pictures up shortly, I left my Ipad at home today. I started a tank thread for the 80 the other day that has links to a few pics (not the best pics). Thanks for the offer of the corals, I need to do a water change on the 30 but it should be ready for corals shortly, and the 80 the I just started to diatoms this week so it still has a week or two before it will be ready.

I will help with you tanks for teachers in any way I can.

The plan for it right now is a mix of soft corals, LPS, and SPS right now. I don't think the lighting (175 watt MH and 2 65 watt PC) I have will support SPS yet but is one of the things I am going to upgrade, but I need to get some circulation pumps for the tank first.

I wanted to say hi to everyone. I was a mainly a lurker before the site went down for a bit, and decide it was time to do some posting now that is is back up and running. I currently have two tanks up and running at the middle school I teach at. A 30 that took a big hit last year when the heater messed up over winter break last year and got very cold. I am slowly nursing it back. I also just set up a 80 gallon bow front about 2 weeks ago. The kids and teachers are very excited to see its progression over this year, so am I for that matter. I worked at my local pet/aquarium shop in high school many moons ago, then took a long break from the hobby. I am finding that what was a go to 20 years ago is hard to find now. I went to 4 shops over the weekend trying to find kalkwasser with no luck (if you where to find some let me know). Jon

Is it running through a timer? I had that problem and removed the timer and it started to fire every time.

Thanks for the help
