When corals start growing from the frag?

ken840515 · Oct 12, 2022

Hello,
I have some corals in my tank for month.
Some of them opens but not growing at all.
Duncan open but not getting extra heads.
Zoas opens but so small.
Leather bended.
Kenya tree so small.
Mushroom is there for almost 2month but not getting big at all.
I am feeding reef roids every other day, 3 times a week.
How long do they normally take to start grow from the frag?

I need to list the following:

- how many powerheads and what kind
- the light model, its mounting height, and the settings
- all water parameters you can test for (including the kits) (include when they were last calibrated and how if applicable)
-what media is in the filter (if any)

You dipped your rock in Clorox bleach 3 weeks ago, killing any bio diversity, and you’re asking why your corals aren’t growing?

Those are some unhappy-looking corals. Corals usually start to grow within a couple of weeks after being added to a system, and how long they take to grow off the plug will vary hugely depending on the type and size of coral and the size of the plug, but those corals aren't going to grow any time soon.

When did you start the tank, and what did you use to start it? What kind of rock?

Definitely test your water parameters, particularly nitrate and phosphate. And ammonia, if that thing about the bleach is accurate.

I like to look at the OP thread history on posts like these. Tends to show details left out now and then.

Hard to take this user seriously when he said his tank has been up and running for 7 to 8 years but then recently joined the forum asking very basic and what I would consider "noobie" questions.

Ah, yeah, bleach will do that. What's happened is, you've un-cycled your tank (so you need to be monitoring for ammonia), and it's going to have to mature again before you can grow corals. Live rock might help, and, failing that, frag plugs from an established tank will help.

Next time, don't do that. Hair algae can be fixed by means other than poisoning your tank and potentially causing your rocks to leach bleach into your tank. You should probably be treating with a dechlorinator, or just outright replace your rock a piece or two at a time.

Reef roids is acceptable but I feed my Growing coral mysis shrimp. Reef roids also increases phosphate levels. Moderate light and water flow and assure nitrate/phosphate not elevated

Omg the rocks should not be looking like that. Its quite no wonder your corals arent doing well at all. It looks devoid of life and taking into consideration you recently bleached your rocks. Its basically gluing frags to an entirely new set of dry rocks and calling it a day. ATP like some have pointed out earlier, you are basically cycling your tank again. Please dont add any more new corals for the time being. Basically if possible leave your tank be to let it reestablish.

there is too much evidence to suggest that its MAYBE a few months old. even if we assumed that he bleached the rock, the sand is new, the powerheads are new, the tank itself is new, the fish are way too small to be anything other than less than a year old, the snails, if there was an algae issue, would have algae on them too (and we know those didnt get bleached), from a previous thread, didnt have a way to test water parameters, and when they did, it was the paper strips. when a proper kit was used, doesnt know how to read them.
too much here to almost take this seriously, or even to diagnose properly because there is nothing truthful here to base anything off of. the easiest corals in teh world to take care of, arent doing bad, but arent doing good. i suspect that these were purchased at petco, or at the very least, bought what i call the "new aquarist petco starter pack". previous posts also show many things that are the same exact items found at petco. perhaps, and hopefully, im wrong. not to bad mouth petco, because they are just a retailer, but people that start off with petco, are most times, behind the curve.

from what i did see, in previous posts, the nitrates are low, which isnt a bad thing, but these corals do like nitrates a lot, so maybe (i doubt it), but with that said, nitrates this low, phosphates are probably as well, and could be part of that issue too. however, knowing that these were soaked in clorox, i cant help but worry that those rocks are leaching bleach, but at the same time, if they were, fish would be dead. however, we dont know anything about fish living/dying, and suspect that wouldnt be told truthfully if it were an issue. i also suspect a lack of good bacteria in the system. i also suspect flow is fighting itself and not flowing well through the tank. i also suspect that the light is a petco purchase as well, and probably not a quality reef light
