Name the top way to healthy tanks

[Coralguy777]

Im looking to setut up a few tanks give me your best method for a healthy tank please

 

[Doctorgori]

-change your water, on schedule and religiously for the first few yrs anyway
- don’t slack on testing, esp Alkalinity 2-3x week minimum
- wipe the hell outta your equipment, esp. under the sump. Keep the salt spray off!
- cheap stuff on Amazon won’t last or will shock you
-don’t get too complex; drip kalkwasser, et
- get hanna Alk (DKH), ULR phosphate, and HR Nitrate …other kits opinions may vary
-pick your numbers and stick to em
- plan a exit strategy for fish that get large

 

[Coralguy777]

Awesome alot of your ideas i definitely do and lol yes the cheap its do shock you 100%

 

[Doctorgori]

Awesome alot of your ideas i definitely do and lol yes the cheap its do shock you 100%

you might wanna keep bumping this as you will likely get some good advice….
one more thing: NAIL down and I mean NAIL down your alkalinity consumption trends, I mean MASTER it for stability. Also get a good top off strategy, before ATO’s were invented, we manually topped off every other day, as changes in salinity means changes in all other params…
and again, keep all that junk underneath wiped down, if for no other reason than you are paying attention to under the tank as well

 

[Paul B]

Only feed live or frozen foods, nothing dry.

 

[coralfishreef]

Budget for an AWC system or semi-AWC. Lugging buckets around becomes more and more of a hassle as time goes by and eventually people will start skipping or forgetting to do water changes.

 

[blaxsun]

Only feed live or frozen foods, nothing dry.

I don’t entirely agree with this. I think it’s fine to supplement live or frozen foods with occasional dry pellet food, if only to get the fish used to something else.

 

[LiveFreeAndReef]

Patience!

 

[JumboShrimp]

Keep your tank empty. Water, sand, fish and corals are sooooo "overrated."

 

[blaxsun]

“Dry reef” for the win!

Lol. you'll have to deal with dust blooms this way.

 

[ZoWhat]

Im looking to setut up a few tanks

IMO start with a single tank for 6mos until you develop husbandry skills.

There is a TON of researching and reading for you to do in the Sticky Threads in the New To Saltwater discussion section

 

[cooltowncorals]

I would work at mastering consistent parameters one at a time.

need to pick targets (lots of options on this) for
Alk
Cal
Temp
Salinity
PH

your choices for these should align with your tank goals, I.e. Fowler, mixed, sps, softies, accelerated growth ect.

Then pick a plan for each one with the basis of the plan being to keep things the same from day to day hour to hour.

I say start with one and work on it and really test and think about things like what will happen to my perfect alk after a water change if I don’t test the new water before it goes in?

most people start with salinity and temperature then go to alk and cal and then start looking at PH and trace minerals and every other thing. Try to master each one then move on.

try not to fiddle to much which can be hard with everything in the trade now 100% adjustable like led lights and pumps it makes more sense to move one coral then change the flow or lighting for your whole tanks

Unfortunately not every coral/fish/invertebrate that you like will have a place in your tank. Try not to force something in that really doesn’t fit. Research things before you buy them and add them. Make sure they fit in your ecosystem.

 

[flashsmith]

They are your tanks and your money. Do your own research and through trial and error find what works best for you. If you read these threads you will quickly realize there are 100 ways to get to the same end result and 100 people arguing you are wrong and they are right even though the end result is the same. That's how conspiracy theories get started... Go the BRS tv route and just come here for the banter and horror stories. Lots of solid information there.

 

[X-37B]

My best advice is to have a plan and stick to it.
Master the big 3 + SG.
Pick your parameters and focus on keeping them in range.
Have all your equipment before you put water in your tank.
Try and visualize what you want your system to look like in 2 years.
Done right you can have a fully grown in reef in that amount of time.
Check my build thread for more info.

 

[blaxsun]

Just remember: opinions are like a**holes. Everyone has at least one,

Great advice for ATO.
I have ran ATO systems since the 80's, before you could buy them, lol.
MASTERING alk as you put it, is the key, to having a long term stable system. Good advice!

 

[Timfish]

Water changes (best way IMO to get rid of hydrophilic stuff detrimental to corals).
Testing.
Redundancy, if any one or two pieces of equipment fail the systme won't crash.
Consistancy (not static, reefs are dynamic and things are constantly changing).
Research.

My long term successes sarted coming back in the 90s when a brief conversation with the director of an infectious disease department of a local hospital started me thinking about bacteria and looking at processes in reef systems holisticly. Since then what I've seen and read has only enforced those ideas. Reef ecosystems are very complex.

Recent research has shown the various forms of Dissolved Organic Carbon (DOC) have conflicting roles and some forms will kill corals a lot faster than nitrates or phosphates. An excellent introduction to this subject is Forest Rohwer's book "Coral Reefs in the Microbial Seas" (kindle ~$10, paperback ~$17). Additionally, some sponges play a critical as recyclers in reef ecosystems and process DOC incredibly fast, 1000X faster than the bacterioplankton in the water.

Interesting info on sponges.
My current sytem has 50% live rock and is covered in sponges under all the rocks.
I have always used live rock, since the 80's, and feel its why I have had great success over the years.
