1. shortcuts lead bad places. Things reproduce and process at a rate governed by biology---and bacteria can only grow and divide so fast, no faster. Suitable warmth helps, but it cannot accelerate beyond healthy rates.

2. tank size and shape governs aggression.

3. too much warmth or pollution lowers the ability of water to carry oxygen. If your tank gets too hot, your critters can suffocate. Too little heat slows chemical processes, incuding life processes like cell growth and digestion. Ideal tank temp for marine rides around 78-80, giving you wiggle room for survival if something unexpected happens.

4. water quality is critical, far beyond just testing ammonia/nitrate. Once your tank is cycled, before you add any living thing, your salinity should ride about 1.024 or 1.025, your ALkalinity should be at 7.9 to 8.3 on the DKH scale, and that is critical!!!!!!!!!!!! Two others to track are calcium (good at 420) and magnesium (about 1350). Do not add any life until you have not only checked these out but maintained them for a week.

5. recently fishes have come in with parasites that can wipe out your population and give you a 72 day cooldown with no fish. Quarantines using tank transfer (see the sticky) are way shorter, eh??

6. be sure whether the coral you're buying is a stony or a softie. They live under different conditions and different lighting. AND dip your corals in a recommended pest-eliminator: for softies, you should also quarantine them about a week in case eggs hatch.

7. having an autotopoff running smoothly is something to do early, rather than later, when you have to leave your tank and have never used one. It's also nicer to the fish and corals, topping off fresh water by the teaspoon rather than the bucket, as needed. See that note on 'stability'

8. buy a light kit adequate for stony corals if there is any hint you will EVER go that direction---having to rebuy equipment is a pita.

9. yes, a sump is a real good idea. You can site it in an adacent piece of furniture if you have to. And having a skimmer is a good idea, but you don't need a killer skimmer unless you're doing the fussiest of stony coral. A good one is usually enough. Softies can get by without, but it really helps with a number of things including fighting bacterial growth, cyano, and nitrates.

10. don't believe in any miracle potions or miracle cures for ich, and never, ever, ever put anything into your tank without checking out the product experiences on RC. Within a couple of hours you can get advice on applicability and effectiveness and alternatives that can save your tank.

11. Never chase a vision of a completed tank without knowing the life requirements of the critters---be alert to photoshopping: and remember the Finding Nemo tank was intended as a horrible example, not a model to follow.

The biggest single issue between a novice and success is usually water quality: run those tests, use ro/di even for initial fill, and keep your nitrates nearly unreadable. Fish may tolerate a reading in the 50's better than corals will, but tolerate is the word. They appreciate clean water.

All good advice. One suggested edit: "use ro/di even for initial fill" should probably be "use ro/di especially for initial fill"

Once you've filled a tank with crud, trying to get it out is a nightmare.
 
You got that one right. It can be done, using water changes and other nitrate remediation, but it's cheaper to start with ro/di.

Great info. Thanks for putting this together.

To correct the problems, 1, weekly water changes, as much as 20% until nitrate levels are nearly undetectable. And use ro/di.
Use dosing (I use Kent DKH alk buffer, Kent calcium and Kent Tech-M (mag) but there are many brands.) Dose mg first, if needed, then buffer, then calcium, but do not add more than recommended dose on bottle (jar) until 8 hours have passed---takes time to dissolve; and do not add alk buffer and calcium within 8 hours of each other. Always have the mg correct: then the other two will behave and not fall.
 
Basically your float valve goes in the sump, positioned (like a toilet float) so that it will not cut on and activate the pump (in the reservoir) until evaporation (not a flush) lowers the sump water level. It's really very basic, and pretty delicate in balance: That 1.020 would be bad for corals. You urgently need a good dedicated saltwater mixing bucket and always test for salinity before you use it. 1/2 cup per gallon (don't know the measure in liters) will give you 1.024 salinity of reef salts, and if you mark a half-cup you will aways use and count gallons, 1 for 1, then you will always come out close. Once you get that ATO going right, you will see it topoff freshwater by the teaspoon, very small amounts, so the salinity in the tank stays steady.

Also remember: you can lower the salinity rapidly a few .001ths and not kill fish, but if you RAISE it rapidly more than .002 of salinity every 10 minutes (proper salinity being 1.024), you can harm fish kidneys and kill them. Raise salinity slowly. Lowering is not so critical. Salinity varies in the ocean and fish do swim between zones, but in the tank there's no place to go for safety if the salinity is going up too fast. Slow is better.

One time when salinity gets critical is during acclimation, but remember that if a fish has been bagged more than a few hours, there's a chemical transformation, as its waste turns to ammonia when you open the bag (ph change from co2 release converts ammonium (waste) to ammonia (lethal chemical)) ---so while you can jump .002 upward in salinity every 10 minutes, it's safer to have a pre-prepared quarantine tank set to the bag's salinity (ask the merchant)---so that you can just pop the fish right into a safe tank of the same salinity, no stress on the kidneys at all, then slowly increase the salinity in that tank to match your regular tank.

I took over a tank created and maintained for many years with tap water (I didnt realize the complication to move to using RO from the lfs). The salinity was 1.29. To correct the salinity I started adding RO. As salinity dropped so did PH and ALK even though I was adding liquid reef and trace elements. I didnt know to buffer the RO and as I corrected the salinity the other numbers lowered. I was confused thinking that a saltwater change would fix it but it didn't. Luckily I mentioned to the LFS and was encouraged to use a buffer in the RO. The numbers stopped dropping and after reading I figured out what had happened. I assumed everyone used RO water.

The information here is awesome and so happy to have a group of people share their experience. Much of the info is about starting new tanks with new sand etc and cycling ...and being super careful... but I learned a lot by rescuing a neglected tank and getting to a path of clean and healthy water quality. I'm sure there are many tanks out there that have this happen...the bubble algae out of control...super high nitrates and stressed out fish...the tank can be turned around with patience and attention. It feels pretty good to solve a problem.
Great info Sk8r, I think I have done some mistakes already:

1) Filling with tap water, I thought I would to water changes with mineral water/packaged drinking water.

2) Did not check alkalinity, Ca and Mg and still added live stock.

:(

3) Temperature is around 82
