I have a 50G reef tank and for several months I have been dealing with high calcium and phosphate. I have done several water changes and every time it goes back up. Some of my corals are doing great and others are dying. My calcium levels are higher than 520 (that's all my chart goes up to) and...

Hello: I'm new to reefing and have a question. Here is the setup: - Innovative Marine Fusion Nano 20 gal. tank with skimmer, carbon reactor. - Lots of LPS corals, some softies, 9 small fish - Tank is a couple of months old - I do a 20% water change every week with LFS water. - All evaporated...

OK reefers, I have a potential issue that I have never seen in my 5 years of keeping a reef tank. My calcium has always run between 420 and 500ppm. Today, it is reading 580-600ppm. Is this bad? Maybe my test kit has gone bad? What do you guys think? FYI: I only dose Reef Complete which is...

I would like to know what would be causing me to get consistent high calcium levels and low alkalinity levels? I stopped dosing purple up 2 months ago and my levels evened out. Now they are doing it again. I change out my GFO and carbon monthly. At the same time I also do water change. I have a...

hi all, I just recieved most of my salifert test kits (Phosphate to follow for some reason!) My mag & Calcium did not change colour to what instuctions say. So off the charts I guess! I tried twice with each just to be sure! So KH 7.7 Ca 500+ Mg 1,500+ ph 8.05 Salinty 35 79.5f Using...

Just set up my tank 2 wks ago, day 3 tested w/ API all parameters were normal for cycling tank except calcium-560. I have tested daily since and my calcium has steadily gone up to 620-today. Does anybody know why this is happening, should I worry and I would ask if I should let it precipitate...

I discovered after testing my calcium levels that they were reading ridiculously high- 1040 ppm (yes, that is correct- twice what the highest level is on the test kit chart I have by API). My Alk is at 8 dkh- good there (but doesnt make sense to me how that can be normal and my calcium that out...

Tested calcium with new salifert kit got reading over 500 ,cheaper a.p.I kit tested at 380,now I am confused. First time using salifert kit might bemaking a mistake.

My tank has been up and running since late March (recent pics attached) The progress of the livestock has gone fairly well, and I've only lost a few things in the learning process. Since the beginning of cycling my calcium has always been at 500 and Mg at 1500. I used 2/3 live rock and 1/3 base...

I know calcium in a reef tank should be around 450, 440 or so but i sometimes here people say they are at 500 or so... can anyone tell me what would happen if calcium is to high??? i have had mine up there before and i just stopped dosing until it dropped but what are the dangers if it goes up...

Hi guys, I'm pretty new to the hobby so I have lots of questions I have a question(s) about replacing my bioballs in my wet/dry filter with live rock. There are 2 media trays for my filter, one is submersed and contains porous glass biocyclinders, the other media tray is above the water...

I just tested my system and two test came back disturbing!!!! The calcium was at about 500ppm and the carbonate hardness was at 230 ppm KH or 11 degrees!!!My PH is about 8.2. The problem is that I have not added any calcium to my water. The only thing I have added is a product called...

I routinely see calcium and alk ranging from 400 to 500 and alk in the 10 to 12 dKH range, I've never had a snowstorm, and enjoy tweaking the Ca Reactor to its max. My usual levels are more like 400PPM Ca and alk in the 9 to 10 dKh, but after a recent issue where I lost many corals (pump...
