Where to get Maracyn, UK

New to this forum.
I'd like to get some Maracyn, but can't find it in the UK. Please could anyone tell me where I can buy it? Thanks

Maracyn is an antibiotic, as such it can only be prescribed by a vet. What do you need it for?

Thanks for the quick reply. My water readings are good in a 125 litre tank - 0 ammonia, 0 nitrite, 20-40 nitrAte. Fish all fine. But can't shift cyanobActeria, which is in the form of slimy dark green coloured covering the plants.

I had a cyno issue, I found changing my lighting times and using a water vacuum helped reduce the issue to almost zero. How many hours a day are the lights on, and how many other plants do you have?

[UKgill]

Lights are on for 12 hours.The tank is quite heavily planted with Java moss, Java ferns, cabomba, acorus, anubia, lace plant and a low growing plant I don't know the name of. Also 2 bits of bogwood. It has been cycled for just over a year. It has 12 Harlequin rasboro, 3 otos, 5 neons, 2 small gold marbled bristlenose and 3 threadfins.
There is one T5 daylight and one T5 nature. Thanks for your help.

Hmm I used to have my lights on for 8hrs a day, and had cyano issues. I've now decreased the lighting to 6hrs, with Java moss, Java fern and Anubias they only need low light.

How often do you water change and how regularly, do you use a siphon vacuum to clean the tank?

I have a 100L tank with a single 39W T5 and do a 30% water change with a siphon vacuum on a Sunday, and use a battery powered vacuum to clean the tank on a Thursday.

The other more drastic but a effect method is to black the tank with cardboard or bin bags and turn the lights off for 3 days and increase the air and reduce feeding.

I use a siphon type vaccuum in this tank, and usually do a 30 percent waterchange fortnightly. But i check water weekly. If anything looks high I change water weekly. My other smaller tanks have no BGA at all. I'
careful not to use same nets/ siphon in the other tanks.
I put black binbags around the tank this morning.

3 days blackout in the tank, covered with binbags, with reduced food seems to have done the job of eliminating the BGA (for the moment at least!)
I put an extra air pump into the tank too, and did daily water checks. No fish casualties. Tank looks much better now.

Glad to hear that helped clear it up.

nice ... good day

[UKgill]

Thanks. All looking much healthier in that tank now. Excluding light certainly sorted out the BLue green algae. ( Cyanobacteria) the good thing is that it hasn't harmed the plants. They were struggling with the algae coating before - and now look much greener than before their blackout.
