From the supplier at Aquaristik shop. "Catalysts have a life cycle of many years and are only replaced if their function decreases significantly."
Plus they should come with 2 catalysts unless they have added another.
How long have you been using Oxydators in marine reef systems Lasse?
What Oxydator, what % peroxide, how many catlaysts are you using and how many gallons is you system?
Sorry I need the rest of your spec as above also how heavily stocked and with what?
You could increase your peroxide to 9% but as always observe the tank closely for at least 30 mins after upping it. I assume given you don't mention it that you have no inverts?
This is my problem when asked about Oxydators I struggle to get all the information required to answer the question in a meaningful way. I need to know a lot about stocking rates gallonage type of animals kept and how heavily people feed as they all play an important part when it comes to getting the best out of your Oxydator.
WOW! You have some great fush there. My friend has a not too dissimilar set up to you using the W model. He is using 12% and 3 catalysts. However I would start with 9% and 2 or 3 catalysts. If all well move up to 12%.
Midas blennies rock in fact I much prefer most of the smaller species of fish over most of the larger ones.
In the UK you have to be VAT registered to buy 35% otherwise 12% is the strongest we can buy legally anyway. Always best to buy high strength peroxide and dilute it to your required strength with RO and post DI if you have it.
