Oh really I did not know that. My Petsmart store does not carry that and they only had one of the Jungle anti-parasite food left but I didnt buy it but I think im going to stop by their tommorow and buy it, unless I shouldnt since I just bought some Maraycn 1 a few days ago. I have not used it yet because for the past 4 days my aquarium has had bubbles floating on the surface. The bubbles look very similar to the melafix bubbles but I cant imagine that it could be. Ive done a 25% water change and a 50% water change in the past 4 days and the bubbles are still their, not as bad though. I added a brand new pouch of carbon for my fluval 205 canister filter and I added a new filter cartridge to my Pengiun 150 biowheel which has carbon in it. I didnt think it would be wise to start the Maracyn 1 when theirs bubbles of some kind in my water so i been waiting to see if the carbon will help. I aslo bought some API/RENA Bio-Chem Zorb today to see if that would help with my bubble problem but its design to fit the Rena filter xp filters which I used to use but switched to fluval. Im thinking about cutting the Chem-Zorb pouch and then putting the resin in a universal filter media bag that will fit my fluval 205 perfect. Do you think this would be wise or even helpful? Ive used this stuff in the past when I had my Rena xp2 hooked up to my existing aquarium and i had great results from it. Ive never had bubbles in my water EVER so im not sure how to go about fixing this problem. Lets say I do fix the bubble problem, would you suggest to start the Maracyn 1 or would you suggest buying the Jungle anti-parasatic food?
