Battling Cyano

[marvelousone]

You do not have any powerbeads in your tank?

I have powerheads. I have a off brand off of eBay. It rated 3250 gph and it plows had. Have a 600gph.

I experienced a constant cyano outbreak that

What are you doing for your nutrients?

Maybe consider an upgrade to the powerheads then.....but can you post a tank shot so we can see how your setup is today?

How do you post a video. Is it the same as a picture

 

[marvelousone]

I order
BioDigest 6 Vials - Prodibio
I am thinking my balance is not right. If this does not work then I will do something else.

I have cheato in sump and I was doing nopox. Skimmer running little on the dry side.

 

[marvelousone]

So I am going to work hard at getting rid of this cyano. The is what it looks like today.

 

[marvelousone]

Ok my first thing is to get good bacteria growing to out compete the bad. So I got this.

Going to dose 2 vials today then 2 on Monday. I turned my skimmer off for about 4 or 5 hours.

My water has a yellow tint. I am running carbon and it is not working so I dosed

I have used this when the tank first started on zeovit. It work wonders. So we will see if it will do it again.

When you say “ I am running carbon”, does it mean GAC? GAC is typically very effective at removing yellow tints in water.

yes GAC in a canister. Started running it last weekend. Still have not cleared it up.

Cyano still going strong. tested po4 today. For the first time it read 0.16 ppm. Checked my RO water and it is zero.

Cyano is a sign of low/out of balance N and P most of the time.

If you're showing some phosphates in testing for the first time, I'll guess that nitrates are still showing something like zero?

If you can also bring up nitrates, you should be able to get the algae in the tank to progress like cyano > green algae > coraline algae.

If BOTH nutrient tests are no longer showing near-zero, then cyano should begin to clear up on its own....look out for the transition (above) and make sure you keep up with any mini-blooms along the way. Upgrade/increase the CUC and do manual work in the tank as needed.

Here is a little update. Big improvement. On the 18th

now today 9/25

 

[marvelousone]

I have not touched it in a week. I have not been home for a couple days. I looked at tank as soon I woke up this morning and this is what I found. The sand use to be solid red.

 

[mcarroll]

Nice improvement!!

 

[marvelousone]

Well the red is back again. I tested my ro/di water. Oh my goodness. Hand tester read 511. I changed out everything on the ro/di unit. Now water is 7 coming out. I changed membrane, 5micro filter, 2- carbon filters and di resin. Now time for large water changes. I will order some more Biodigest.

 

[marvelousone]

So I did a 30 gal water change after changing the filters. With in a week the sand cleared up. I do have some on the rock. I added a larger return pump. going to see what that will do.

 

[marvelousone]

I still have cyano. This is getting old. I ordered a hanna tester for po4. It is the phosphorus ulr. it read zero.

Man i really feel for you. I don;t have any solutions, just sympathy...

When I had Cyano the owner of the LFS told me to make sure I killed it all with the first treatment of chemi clean or it may build up resistance and become super cyano. I ran it 24 hours and that got rid of 95% of it. So instead of doing the water change and a second dose, I let it go for an additional 12 hours, and it has never come back. My system is very small though. 32 gallons.
