Immune Plus - Freshwater - 5 oz.

I used this when I started up a new 55 gallon planted tank recently. I figured that the extra protector bacteria would support the other bacteria in the biological filter. While I was using it at the recommended doses I had no problems with illness.

There are other factors that were going on at the same time (like introducing fish that were sick, but not yet visibly sick), but when I started to taper off on using this (because I was running out), then I started getting problems. The tank had an outbreak of both camalanus worms and tail rot within two weeks. The bag of Chemi-Pure Elite I had in the filter was also running out around the same time, so I don't know which thing caused the outbreaks. Most likely it was a combination of factors.

If you have plenty of money this is definitely worth purchasing. If your fish keeping budget is more restricted... I would recommend covering the more basic and proven water treatments, like Black Water Expert 16 oz. before you buy this. Also, if I had to choose between this and the Chemi-Pure next time (and I do), I will put my money toward the Chemi-Pure.

Finally, shop around for this. The shipping charge that's listed here is way too pricey.
