I’d like to hear more details. If you needed encouragement
First, let me say that I don’t know if this is the way to go for most people. I’m a pretty big risk taker for huge potential upside and I’ve just gotten sick of losing coral.
I have an IM40, IM30 and a 22 gallon tank connected to a single sump. A couple of Euphyllia and a bubble tip started melting after the addition of an elegance coral and I’ve been around the block enough that once torches and hammers/spawn start going downhill because of BJD/Bacteria it’s goes fast and furious.
So I went extreme; nuked the tank with antibiotics (ciprofloxacin). Total actual water volume is (I’m guessing) around 100 gallons. My dosage was based off of 500mg/20 gallons, but I threw in one extra 500mg pill to account for any absorption into rocks/sand. So a total of 3000mg per day. Dosage should occur after lights out (cipro is light sensitive). I suggest that you repeat the dosage for at least 7 days, but I usually go for 10 days. Put the cipro in a high flow area or place somewhere where you can aid in dissolving/mixing in the tank.
At this dosage level, I never saw any issues with ammonia or nitrite. But you should make sure you are checking both daily and be ready for a big WC if needed. I also had a Seachem Ammonia Alert badge in the tank. Some recommend daily changes in water, but I don’t see the point if your nutrient levels are held in check. Fish, inverts, macro algae and coral did not seem to be negatively affected by the cipro.
some things to note:
- It is an absolute must to turn off any UV sterilizers as ciprofloxacin is light sensitive and will break down
- remove carbon
- no thoughts on skimmer, but I’d turn it off at least during lights off when the cipro is “active”. When it is first dissolving, it breaks off into tiny little pieces and I could see those easily riding up some bubbles.
- I did not change my feeding schedule or lighting schedule
- coral in tank are euphyllia, BTA, Goniopora, cataphyllia
Usually after treatment, I used to throw in Dr Tim’s one and only, biospira and/or microbacter 7xlm just in case. But I actually keep a super clean (no fish, no coral) seeded tank/bin growing chaeto now. So I just throw in media/rocks from it when needed.
so now the real question is: did it help or do any good? I’ll never know to be honest. What I can tell you is that no new euphyllia or anemones have melted after the original 3-4 pieces I lost. And some that started to show potential signs of melting (receeding flesh, steady deflation) have all perked up and look like they’re back to normal and grew back some of the receeding flesh.
Here is the euphyllia tank tonight. Treatment ended yesterday.
