Furan 2 for cyano?

[F15hguy]

has anyone had any experience using furan 2 for Cyano, one of my Display tanks is making me tear my hair out, and being a store display tank I can only do a partial black out if at all....

I've only used erythromycin for it which worked well... If you can get it that's what I'd suggest.

What happens after you treat the symptoms? The cause will still be there and it'll just come back. You need more flow dude.

There was a shop down here that told me they used that to cure cyano and I tried it and it works. I used eurethromycen once and lost a lot of fish---probably killed the bugs in the filter. I have used it on other occasions without problems. Prescription only is the problem with E.

Cause already sorted, unable to increase flow due to design of tank (all the cords are built into the stand :an!gry )

was a phosphate increase due to someone adding "pond" fertiliser sticks, and I forgot to turn lights off over night.

water changes have fixed phosphate problem (down to 0) and Nitrates are barely registering on the test (so around 0-2.5 ppm)

even though it still manages to recolonise in about 2 days.

you need chemi clean.

distributor is Aquanet

Cleans many types of stains from cyanobacteria

Works in fresh and salt water

Completely safe for all fish, corals, invertebrates, and nitrifying bacteria

Chemiclean cleans stains from red, black, blue-green, and methane (bubble) producing cyanobacteria in marine aquariums.

It is completely safe for all fish, corals, invertebrates, and nitrifying bacteria in reef systems. It’s simple, quick and easy to use. Chemiclean works within 48 hours oxidizing trapped organic sludge and promotes an ideal enzyme balance. Chemiclean will clean stains from red cyanobacteria in aquariums.

Ok, but will it get rid of the cyano in addition to cleaning up any stains from it?

[fishy11]

Cyano can still thrive without phosphates. It is a bacteria, so they can easily adapt to thriving off other compounds in your tank. Hence why it is a pain to get rid of and one of the only things that can get rid of it is provided by vets as an anti biotic.

Once it kills it off you need to physically remove the dead cyano as it will sit in your tank and rot if not removed.

[Adrienne]

Both furan 2 and erythromycin will kill cyano. Working at a shop with tanks I would have expected both to be in the fish first aid kit?

Cleans and removes, heard good reports about it working well, using antibiotics is not ideal as it kills your filter bacteria.

Yup, Cyno thrives when phosphase are too high or too low, when Nitrogen is in excess and CO2 is too low relative to the light level. It can only thrive when the balance optimal for plant growth is upset. It can also thrive if there is too much UV vs nutrient balance and CO2.

In tanks with no plants cyno says YAY!!!! - Especially when nitrogen is in abundance.

[reef]

Whilst medication is a quick fix, you need to find the underlying issue which is likely to be high nutrients.

Also high temps in summer seems to bring out cyno.

Vodka also held to reduce cyno

[Warren]

Although, I find too much vodka makes it more difficult to remove. 8)

But a little more than that and you don't care.

unfortunately Furan 2 is long gone and had no need of it for over a year, not even for customers.

erythromycine is prescription only and therefore costly (plus has a shelf date) so is not worth it until all options are expired.

[Joshlikesfish]

You could always try some melafix and pimafix :gigl:

[#!CrunchBang]

what about ultralife blue green algae remover? Seemed to work well for me

[Barnacle]

Ever tried hydrogen peroxide? I had a bad outbreak in a small tank, and i put i think about 1ml per 5l (of the 3% strength stuff) and within a day or 2 its all gone.

[Clearbear]

I used Furan 2 for my tank when I had it and I haven't had a problem with cyno since

I thought you weren't supposed to use H2O2 in an aquarium because it affects the pH?

I think that has been proven to be a myth dude, people use it all the time to help kill different types of algae with great success. In larger doses it would be harmful to fauna and beneficial bacteria though.

This is the problem I have in my native tank, so I have taken to growing basil in the tank. Time will tell if this helps or not

[F15hguy]

attempting a lights out (wouldnt call it full black out) for 3 days while I wait on the next order that should contain furan 2

if I don't get it, have a friendly Vet nearby for the ethro...

we shall see what happens.

Please beware of the advice you are imparting.

H2O2 is a very powerful oxidising agent and will burn your fish's gills. It will kill them along with any plant and algae in stronger doses. It is very effective at killing algae - but at what cost.

I should know. I wiped out an entire tank with thousands in livestock in one go.

[Godly3vil]

P44, nothing in my statement is incorrect and I even warned at higher doses it will be harmful so why should I beware?

Just because you had a bad experience using it does not mean it shouldn't be considered. Just Google it and you will find just as many people that have great success using it on all types of algae with no ill effects.

People do use it with great success but of course being a dangerous chemical there is a risk of harming livestock. If I were ever going to do it I would just spot treat the affected areas with the filter off to give it a longer time to be in contact with the affected area. Only for 5 minutes or so though.
