Mardel Maracyn

$ 49.00 until FREE shipping


Maracyn's active ingredient is Erythromycin. The savings come in the large 24 pack or larger over the traditional API Erythromycin. Each packet treats 10 gallons.

Don't confuse this with Maracyn 2, which isn't the same we don't currently carry.

Worked great

I had Cyanobacteria for several months. I tried other antibiotics to no avail. Gave erythromycin by Mardel a try and within 48 hours it was gone. Just two doses and gone. Thanks A Coop for suggesting it.

Trio

I’ve been using Cory’s trio now for a half of a year with great results. This medication as well as API cure all and ick-x has been great. I’ve used the three in planted tanks with shrimp and snails with no fatalities. I’ve not found enough info to guaranty the safety of fry but wouldn’t be shocked if it was safe for fry as well.

Misleading

On the medication selection page, it shows the 24pack of maracyn for $11.99. I was in a rush and ordered it without noticing the 8pack or 24pack selection. Very misleading, please change the picture or change the price to match.
