What's the one change you made to your tank where you noticed the most improvement-- in overall coral and fish health?

It could be equipment/placement/maintenance/mindset or philosophy/photo period/fish/anything really....

I know this could be difficult, as often times people change more than one thing at once, but just throw some ideas out there. .....Just trying to start a discussion and maybe find some trends (or at least make them more obvious).. and bring to light ideas that may be overlooked by a rookie, and yet taken for granted by a seasoned reefer.

......as a side note; please don't say something like "stability".. of course "stability" is going to improve your tank. You could substitute that with a phrase such as "when I added an Auto Top Off System it made the salinity levels much more stable".. The point is, be specific. You can also have more than one idea.

changing all my koralias for a Vortech Mp40w made my corals go on a birth spree (best investment)

Another change is increasing my photo period to 12+ hours a day.

[E.intheC]

definitely. Flow is huge. I noticed a big improvement on my LPS corals when I sold an MP10 (had 2 going on a smaller tank.. it was just too much).. now that I've switched tanks and I'm trying to get more SPS, I wish it was still there

As for photoperiod.. I've heard the same as the above, but I've also heard of people reducing their photo period to 6 hours/day with no ill-effects.

When I first started I bought pre-mixed SW and had a 29 biocube. It was an absolute disaster. My best change was getting an RO/DI system.

For me, besides the given of regular WCs and a good skimmer, lights etc, is the addition of sodium absorbate (vit c, buffered power pharm. grade form) twice a day. I have been in this hobby for a pretty long time and dosing this has profoundly affected my coral color and overall health.

Feeding zoas when I feed my LPS. It's made them spread like crazy.

Just feeding corals in general (small amounts of phyto and marine snow) has made a huge difference in growth. The only "sacrifice" is keeping params in check while doing this, but that's not really extraneous.

Do you guys spot feed or broadcast feed?

[kroman]

Because i tend to feed my corals quite a bit I would have to say using "Special Blend" has been a great way to keep my tank in check from excess nutrients.

Vodka dosing! Never had really high nitrates but they where there even with weekly water changes. Started Vodka dosing about a month and a half ago and I very happy with the results so far.
