zooanthids not growing at all

[stan80]

Have a couple of diff colonies of zooanthids for 8 month's now and there
not growing at all...my phospates and nitrates are very very low is this the reason??

[xxmindgamesxx]

Have you been feeding them? No i assum?

Well it might be the lighting.. what kinda lights do you have?

I got one aquabeam 600 led strip 12 watt 18,000k , one aquabeam 600 led strip 12 watt 14,000 k and one 13 watt t2 blue bulb and one 11 watt 6500 k bulb...50 gallon aquarium with 30 gallon sump approx water volume 60 gallons. My leather coral is growing very fast and lps favite is doing good too...oddly the zoes and mushrooms arent

What about the placement? Did you consider that? If they're not growing then there might be too much flow..

Ive moved them some but no not alot...Overall flow is about 40 gph. They are located well under the powerheads

[stan80]

40 × that is lol

No growth for 8 months?
Another LED problem... Get some good t5s over that tank to start with.

No problem growing zoas for me under LED, but im at 100w on a 55g you look to be around 67w.

What do you think it could be then?

It could really be a light problem.
But if not.. there are also many other things too look for.
You should write a text with all the info people normally post so people could try to help you better.

Im not saying its not lighting for the op. You made a blanket statment about LED. Some of us have no problems growing under LED.
I do think the op is low on his wattage total for lights.

Well, let him say for himself then.
It was a "blank statement"! You're right.
That's because I'm tired of seeing too many people with LED problems. LEDs aren't still for reef aquaria IMO. Not for the long run!!

His problem CAN really be the LEDs yes!
What if that's the only problem?

Good luck in the long run, my friend.
watch out... if you post anything wrong with your system I would say the LEDs are the problem.

... Then you're going to be bashing them!! Haha!!!

Stan, nowadays I tend to look into lighting the system first before I see anything else wrong. Most times I loose my time trying to identify wrong things in the water chemistry, pathogens, and other areas when the LED light is the problem.

People really thing those LEDs are OK to use over a reef tank for long periods of time. You can, but sometimes, depending on the system you'll have what's going on with you... Out of nothing. Many reports like yours...

Like I said before...
you'll need to post everything about your system so people can help you out.

I'll aways recommend T5s instead LEDs simply because more and more people are coming to realize the negative side of those LED systems. I'm tired of it.

Im not sure what you want him to say for him self. Does he have low par maybe we dont know.

Im not sure why your stuck on "it can be his lights", no one said it wasnt a light problem.

Lets focus on his low light problem not your LED bashing.

I took three zoa polyps and they have grown into 20 in 6 months.

To the op, i hope you find helpful answers. I think its a mix of light and not enough food for them, as in bio load not actual feeding.

I dont have much more than a year in this hobby but have learned most coral have to adjust and be happy to start growing. Then its usually a sudden burst.

Well, I'm sure you'll be greater help then me with LEDs!
You help him please, would you?

Grandis.

[stephen.davis.]

I would be glad to help another reefer.

Stan80, your low nitrates could be the problem, direct flow could be a problem, lights could be a problem, the answer to your original question is it could be, but you havent given us alot of information to go off of.

hmmm this thread became way off topic for the op.....

That is what happens when someone seems to be pushing an agenda.
Though it is possible that it is light related, so not entirely off topic.

I've read a few threads where it just takes a while to get the tanks going. I have some zoas growing very nicely right next to other zoas that haven't grown in a while. Could be any number of reasons.

[blasterman789]

A Grandis is a poster child for what's wrong with these forums and the general lack of science education in general, and I urge those sick of his comments to not let up on the criticism. Every reef problem along with incontinence and hemorrhoids he blames on LEDs, and if he were making his comments in the general forums he'd be bashed to pieces.

My first reef tank (30 years ago) was a cheap, 28gal plexiglass hex, and I could never get anything to grow in it. So, I should log onto reef forums and claim 'you can't grow coral in tanks with more than 4 sides'. That actually makes more logical sense than A Grandis does and his anti LED flat earth speak.

In the past 5 years I've grown out multiple 15-20gal tanks with zoa gardens so effing dense you coulnd't see rockwork, and all were under custom LED fixtures bright enough to scald SPS. I'm giving away frags of purple hornets, king midas and gobstoppers because they are over growing my tanks, and I have to listen to this guy say you need T5's.

The formula for excellent zoa / paly growth in my experience is moderate nitrate (5-10ppm) and higher pH if you are running smaller tanks to compensate for C02 saturation (carbonic acid is bad for zoas, and kalk can fix this) along with elevated magnesium (not sure why, but it seems to help likely because it reduces competing bryopsis). Since my tanks all run low nutrient on their own because I keep low bioloads I now add potassium nitrate to keep nitrate at 5-10ppm, and zoa growth responds accordingly. Some larger palys (purple deaths / Sunny -Ds) will devour mysis or brine shrimp if dropped on them, and this drastically helps growth. Smalles zoas are filter feeders though.

Liquid suppliments like oyster of zoo fest don't have enough protein mass in them when used in larger tanks. I use 4 caps in one of my 12gallons just to get a feeding response.

[garygonzales]

+1 on this..........thanks blasterman...im with you all the way on this one...lol....

[stan80]

Ok my parameters are ph 8 -8.2. Calcium 415..alk 8.8 - 9..nitrates always untraceable. Phospates 0 - 0.5 . Maybe I did get too much into the led company telling me there lights are #1 and they even did win led lighting of the year and there par/pur charts show good high numbers.. I do have a couples t2 bulbs ( those pencil size bulbs ) with the 2 led strips and there charts show those t2 to have goood par too...plus the bulbs are only 5 inches above the water surface and my leather coral is growing fast. Also the zoanthids arent directly in front of the powerheads or nothing plus I have some other frags in other places in the tank and they not growimg either..I said 8 months but I looked and it's 7 months ive had them..I do have some mushrooms also and they are not spreading but are growing larger...I have only been into saltwater for a yr now and the zoanthids was the first corals I got cause all I read was they would grow almost no mater what .

[sde1500]

They like a little nitrate in the water. Undetectable is too low for them usually.
