AEFW X Treatment

[enlighten]

I plan on using AEFW X on my system as every other option seems a bit extreme or risky for my situation. I read through the HTU and the only concern I have is dropping my temps to 23C. I plan on dropping to 74.8-75.2 as my range. But it just scares me.

Tank is a FijiCube 32 EXT with 12g sump, will be using a JBJ 1/15HP to get the temps. A hydros single head doser, doing 5ml at noon every day (mid light cycle), and fish wise i have a springer damsel and royal gramma that may help. Considering a 6 line or possum wrasse. Afaik my flasher wont do much.

Any tips are greatly appreciated! Base of the frogspawn is getting white and Ive seen bite marks on a few other frags.

AEFW X treats for acro eating flatworms. It doesn’t seem like it will do anything to combat the pests on other corals such as your frogspawn. How many SPS corals do you have in your tank? For that size tank it may be easier to just treat the affected SPS directly by dipping or spraying them outside the tank.

I meant ORA Frogskin Acropora. I have 3 main rock scapes, all covered in acropora. I would rather not not take out all my rock and dip it. I feel it would be too much of an ecological disturbance. And crash my tank.

FYI tang is a rental from my LFS, had a serious case of hair algae and finally beat it! Will be returning the guy this weekend.

Okay so the chiller is all hooked up! Have it in take and return in the middle chamber of the sump. Cant do much about that. But here is the issue. The temp swing is 2F... isnt that too much for sps coral? I just understood that this morning and it dropped mt tanks temp 1F in 20 mins. I feel this shift is quite intense so I decided to take it out of the plug I had it and place on the apex instead. I didnt like the idea of it turning off and on all the time but I do want to keep my corals with a minimum temp swing of .5 degrees. Is this achievable or am I overcomplicating it all.

I assume 2F isnt bad but depends on how fast it happens... what is fast? I an going to do a bit of research. The other issue is the temp reading in my sump is off since its all in the same chamber. It gets colder than my display. So i let my chiller run to drol a degree in the sump, but after adjusting with display temps, its now at 77.4.

This is my tank with just fans

I wouldn’t worry about a 2 degree F swing. Here is what AI says:

Corals on the Great Barrier Reef experience surprisingly small daily temperature swings compared with many home aquariums.

Typical patterns are:

• Outer reef slopes and deeper reefs (5–30 m): often only 0.5–1.5°C (0.9–2.7°F) variation over a day.
• Shallow reef flats and lagoons: commonly 1–3°C (1.8–5.4°F) daily swings.
• Very shallow tide pools and isolated reef-flat areas: can occasionally experience 4–6°C (7–11°F) or more between cool nighttime lows and hot afternoon highs, especially on calm sunny days.

For example, a coral on an exposed outer reef might see:

• Night minimum: 27.2°C (81.0°F)
• Afternoon maximum: 28.1°C (82.6°F)

That’s only about a 0.9°C (1.6°F) swing.

By contrast, a coral in a shallow lagoon might experience:

• Night minimum: 26.5°C (79.7°F)
• Afternoon maximum: 29.0°C (84.2°F)

That’s a 2.5°C (4.5°F) swing.

The exact amount depends more on depth, tidal flushing, and local water movement than on location along the reef. Corals on wave-swept outer reefs live in remarkably stable temperatures, while corals in shallow reef flats regularly experience larger fluctuations and are often more tolerant of heat stress.

For reef aquarists, this means that a daily swing of about 0.5–1.5°F (0.3–0.8°C) is completely natural and insignificant. Even 2–3°F (1–1.5°C) daily variation is common for many wild corals, particularly shallow-water species such as many Acropora.

Yeah my concern isnt exactly the amount of temperature swing, its how fast it is taking place and how often. My chiller might kick on 2-3x per day. I still need to verify through regualar usage.

Alright i increased my return pump and now i can safely pump thr chiiller from the second chamber to the return chamber. That solves one issue. Now my apex is acting up

Well just noticed a leak. Any idea where i can get this socket(3) part? #7 @JBJ Aquarium

 

[enlighten]

Unfortunately JBJ said this part was not an easy replacment. So I bit the bullet and ordered a new unit from Chewy. This may be an issue with older models and the new ones dont seem to have this nylon socket. Something to keep in mind if buying used!

In any case, the AEFW has arrived today from Saltwater Aquarium. Since I want to follow the HTU by the book, I will not start treatment until the chiller is setup and temps brought down to 75F. Additionally, I am getting a yellow coris to assist with the pest control. I would have opted for a possum if the choice was available.

Updates following treatment startup!
