Korallen-Zucht ZEOstart 3 Tank & Coral Accelerator Information

ZEOstart 2 Tank & Coral Accelerator

ZEOstart accelerates the cycling process in new tanks. Fishes, hard and soft corals can be added safely in approximately 3 weeks after adding water to a new tank. ZEOstart should also be used in tanks that are already running the ZEOvit system. ZEOstart brings out amazing metallic colors in Acropora, Montipora, Stylophora and Pocillopora. Soft corals grow faster and show better polyp extension. Skimmers produce up to 100% more dark skimmate than before dosage of ZEOstart. Dosing: directly into the tank 1-2 drops per 250 gallons/1000 liters per day. This product is HIGHLY concentrated.

Manufacturer Info

Korallen-Zucht is a German based company who offers a full line of additives and filter media for saltwater aquariums. Their ZEOvite products can be used with or without the use of a ZEOvite system.

Comments: I began using ZEOfood and ZEOback about a month ago. I immediately noticed increased polyp extension on my corals. The flesh on one of my Sun Corals had started to recede and this has reversed since using the ZEO products. I have an established reef tank (approx. 5 years). The ZEOstart can be used as part of a regular dosing program also. Although I have only been using the ZEOstart for a week my tank appears cleaner, which I am attributing to the addition of the ZEOstart to my dosing program. I highly recommend these products.

Comments: I've been running the core ZeoVit program on my tank for about 3 months now. The nitrates and phosphates are gone, despite extremely heavy feeding, and my LPS corals and Zoanthids have turned crazy colors. Much more convenient than homemade carbon solutions that have to be tossed and remixed frequently.

Comments: I am using this product in a new 30 gallon nano plus refugium set up. To evidence its effect, I have been monitoring a mature leather coral (and its polyp extension) that I moved into the system at approximately week six of the cycling system. My nitrites were still high (at 1.0) and my nitrates were at 15. Within 4 days of dosing, my nitrites have dropped to .025 and the nitrates are at 5-10. Whereas the store I purchased the coral from originally had had to wait 2-3 months for full polyp extension, I now have a beautifully colored and completely extended coral that looks like it belongs in a show tank. I also started the ZeoVit program as I began with the ZeoStart, so I am sure that has contributed, as well. I am running the ZeoVit tank side-by-side with a tank in which I am using the German Balling dosing method, so we will see. I expect this to take time to truly evaluate fairly, but so far, so good.
