Yes, I run a canister filter, run carbon all the time, change it about once a month. Running an nitrate reducer in there now but can't remember what it's called off hand. It's a rechargeable packet like thing.

The powerheads have the sleeves. I wasn't running them and then ran them the last 2 water changes with brand new sleeves each time. They are now out again because my friend who owns the LFS said they can be a source too.

I'm pretty sensitive to the taste of heavy metals in water and I drink our tap water so I'm not sure that is a source.

Wow, this sucks, I feel your frustration! In my opinion you should ditch the canister. They are ok for fish only but personaly I would never use one on a reef system. Nitrate factory. Open a window or two and get some fresh air in, this will help raise your Ph some. I am thinking you may have too much bio-load for a 75gal. What with the population explosion of your snails and the 7-8 fish your filtration can't keep up. Also, invest in a RODI system, you may not be able to taste metals... but they are there. Hope some of this helps and good luck!!

If you can get a hold of a bottle of Prime and also Stability from the lfs or a local reefer do so. Both assist in getting the bugs into turbo.
At peak time how many snails and hermits did you have in your tank.

I would see if you can get a copper test, copper is one thing that really affects corals and inverts but seems to be not bad on fish.

Sorry with your amm and nitrite up it looks like you are having a cycle again ? im not sure why but those suggest that

You are so right Steve. Can't say it enough, calibrate regularly! Also a good ro/di should be your very first purchase before anything else. I went for a year without one on an existing tank until all of a sudden phosphates went up in my source water. Took me a year to get over the algae outbreak! With the current flooding I am going through the color changing DI resin at an alarming pace! Something is getting through Calgary's water treatment plant that would be in my tank without ro/di

Sorry to hear that man. That sucks. Have you tested the source water for everything? Just a thought. I know there is something extra in my source water just haven't tested it yet. Burning through DI resin at an alarming pace!

Going to test the tap water now before I do another change tonight. I have to be sure. I just have my typical tank test kits though, nothing else.

Someone also mentioned that I forgot to post SG and it has always been in the 1.024-1.026 range when some evaporation happens. Currently at 1.025 though.
Plus, I do calibrate my refractometer whenever I change the carbon, so every 2nd water change on average.

At highest point I had 10 large nassarius probably, 10 mexican turbos, 10 astrea, sand sifting star fish, conch, 1 blue hermit, 2 halloween hermits, cleaner shrimp, banded shrimp, pom pom crab, urchin.

MIA is the nassarius (they all used to surface when I fed the fish, now I only see 2), cleaner shrimp, pom pom crab, plus I'm down probably 2 turbos and 3 astreas (but tons of babies). I think my one wrasse is eating my snails too. It seems to harass them.

Huge spaghetti worm population die off (even on the rocks), minimal algae in the tank, some cyano and dinos right now. Now I have probably at least 10 red serpent star fish show up out of nowhere.

Do you have a second tank (QT) you could set up for your primo livestock whilst you figure this one out? Maybe a fellow CanReefer in town?
Perhaps something is dead behind your rocks? Also live rock doesn't last forever, it's always a good idea to add/change out a piece or two every year or so. Keeps diversity in the good critters.
I still recommend a RODI system, this would only be good for you and your livestock.
Take some water to the LFS and have it tested if you don't have a master kit.
If it were my tank I would be going crazy right about now, as I'm sure you are! GOOD LUCK!
