View Full Version : cyano (curse!)

01-26-2013, 10:26 AM
My test result's , however still having Cyano outbreaks.

01-25-2013 - Aquarium -
Ammonia (NH3-4) =. 0
Nitrite (N02) = 0.004
Phosphate (PO4) = 0.02
Nitrate (NO3). =. 1
Silica (Sio2-3) =. 0.8
Potassium (K). =. 441
Ionic Calcium (CA). =. 126
Molybdenum (Mo). =. 0.1
Strontium (Sr). =. 8.1
Magnesium (Mg). =. 1350
Iodine (I). =. 0.05
Copper (Cu). = 0.02
Alkalinity (meq/L). =. 3.8
Total Calcium (Ca). =. 500

230 gal display with 125 gal sump
4 - MP40 Vortech pumps and 1 - MP60
3 are mounted low and 2 are mounted a little higher, great flow
Feeding 3 frozen cubes per day, I have 13 fish
Running a phosphate reactor using BRS high capacity GFO, I change it monthly
I do 10% water changes weekly and sypon Cyano out weekly with water change.

I been reading some forums, Keep skimmer cup clean more often and clean skimmer body once a month. Watch feeding frozen food.

Any other suggestions?

What kind of lighting do you use?

01-26-2013, 12:52 PM
Radion XR30 LED's run in natural mode

01-26-2013, 08:11 PM
Have u treated with Chemicals yet?

01-26-2013, 10:25 PM
It doesn't take much for cyano to take off in your tank. It usually will only grow where there are dead spots with little to no flow. I had a big outbreak last year but after I removed it and moved my returns around it hasn't come back. I get a little here and there by nothing major.

Can you post pics of it at its worst?

01-26-2013, 10:37 PM
I had no luck with Ultra Life Red Slime Removal. Will post picture tomorrow

01-26-2013, 11:15 PM
Slime remover worked great for me one dose and it was gone three years and counting
Did u turn off your protien skimmer when u treated it?

Water movement should not be an issue, how long is lighting? Are you using ro/di? What is your live stock? Clean up crew like? Your feeding seems to be heavy to me? Do you rinse the food before you feed?

01-27-2013, 12:34 PM
LED's are 2 months old and I don't rinse the frozen food
13 small fish, however one large hippo tang.

500 Cerith Snail
30 Blue Leg Hermit Crab
20 Astrea Snails
1 Halloween Hermit crab
25 Peppermint shrimps
5 Nassarius Snails
1 urchin

I took this picture today, before I change my water and syphon as much as I can of the Cyano out.

Just some background information. I setup this current tank December 2010 with establish rock. The proceeding year's the tank did well all SPS grew well, however about 7 months ago the SPS started turning white and I determine it was because of low salinity and a parasite. (Long story! but parasite was killed off) I determined at that time to do a major overall to my live rock (it's been in all my tanks so 8 + years)
I added over 150 pounds of rock that was outside in the sun for months and then pressured washed, then cycle for 3 months. Since then I have I started seeing small amounts of Cyano. So I tested for phosphates and had some high readings. Which I control now religiously with GFO. Then religious water changes with syphoning of the Cyano, and adjusting my flow. However I'm not winning the battle. There are different views about treating with chemicals and I always lean towards a more natural approach.

PS: I use RO/DI water and I change the filters every 6-8 months.

do you use chaeto in your fuge??

01-27-2013, 03:29 PM
Yes I have Cheato ' however never had much growth. Must be too much flow. My sump is 72" x 18" x 25" so it's built in and my return pump is a Reefo Dart.
The below picture is after my water change and syphoning

try to over load your fuge with cheato it will use up all the excess nitrate that the cyano needs to grow.. the cyano is more than likely out competing your cheato for the nutrients in the water. which is why your cheato isn't growing.. i also suggest if your feeding cubes mysis/bloodworms.. dissolve the cube in a cup in tank water then dump the water out of the cup through a net and feed that way. those cubes have a lot of TDS in them

01-27-2013, 06:14 PM
Sounds good, Does anybody have Cheato they can spare?

01-27-2013, 06:49 PM
i wont trim mine for another 2 weeks probably. there are a couple good places to get some on ebay.i keep about 3 pounds in my fuge and my total system volume is about 115 gallons.. also do u have a tds meter on your rodi unit?

You can post in the Buy Sell forums, there are plenty of places to get it locally.

Check this article:

I think you would have better luck with flow, manual removal (which you are doing) How long have you been running your GFO and how do you have it plumbed in? As in how much water actually makes good contact with it?

Some of my customers have been having some decent luck with lights out, and red leg mexican hermits.

01-27-2013, 08:25 PM
I have a TSD meter on my RO/DI, I've been running GFO for 5 months.
Mag 450 gph feeding it using BRS high capacity GFO in a GEO's Reef model no. UMC420. Good flow moving the media very nicely

The Radion XR30 simulate sunrise and sunset never really tried a black out. I do have some hermit crabs

cyano is a form of bacteria not algae reducing your light cycle will not affect cyano bacteria it is a hybrid form of algae/bacteria in low light conditions it will not die. only switch over from photosynthesis to using nitrates and such nutrients that are available in your water to grow still... low flow rate is a prime reason also for cyano growth. your mt should have a 20-30 times an hour turn over rate. and i thought it was blue legged hermit crabs that have been observed eating cyano.. there is no such thing as a cyano eating hermit crab.. most hermit crabs are Detritivores a mainstay in their diet is detritus and algae.. cyano is a hybrid form of algae/bacteria so its not really considered algae. its all comes down to three things flow rate,lighting, and nutrient removal.

A three day lights out period will most def. kill off any cyano in your tank. I know because I have done it. Make sure if you do this to do a big water change afterwards. But this is really just a band aid and it will grow back if you don't find the problem.

I have heard both red and blue hermits eating cyano, but have yet to hear of any having a long life of doing just that.

01-27-2013, 08:44 PM
Ok I'll change my GFO and crank up the 5 Vortech pumps

01-27-2013, 08:50 PM
Thanks for everyone' help. Now if the Pens can win the shoot out

01-27-2013, 08:55 PM
Pen's Win!!!!!

01-28-2013, 08:23 PM
i have chaeto you can have

01-28-2013, 10:10 PM
Can I pick it up some day this week?

01-29-2013, 03:33 AM
Chaeto will help, but I think you need to cut back on feeding, light cycle, monitor tds in source water also. Combo of stuff. Ive used chemicals to off cyno in the past. I know its not the natural way..... but, neither is 300 galllons of salt water in your living room.

01-29-2013, 04:25 PM
yeah you can pick some up. send me a text 724-four5four - three o 5 one
