Thank you for getting back to me. I was having a problem with alkalinity being all over the place I couldn't get it to stay stable. As of now it is staying pretty steady.Hello,
it is very likely to be cyano. There are couple of ways to deal with it.
In general, they can be a result of any imbalance in the tank. As such, it could be linked to your recent tank change.
Before using any chemical, I would check the circulation - if it is “strong enough” and that there is not dear spots in the tank.
It would be great to have a bit more info or picture of your filtration.
Again, they are not nice, but not very difficult to deal…
As soon as we discover the root of the problem… then it is possible to define the best approach to deal such: siphon, blackout, chemiclean, change in filtration or circulation, adding bacteria…
Cheers!
Yes I am using rodi water with every water change and in my ato. The hanna checker is not ulr. I could buy that if you believe it to be better/necessary.Hello,
thanks for the extra information!
It is indeed possible that the cyano is linked to the change. As a first sight, I don’t see anything else “obvious”.
Can I assume that you use RO-DI water, right?
Phosphate Hanna - is the ULR?
If I may, I would suggest to do the following:
- water changes + siphoning as much as possible the cyanos (weekly?)
- potentially add some bacteria, such Dr Tim, Microbacter7…
- keep checking if the circulation of the tank is appropriate.
- You can add an extra step, but this one depends a bit on how the corals (if any) are at the moment.
Meaning if they are fine or recently stressed.
In case if they are all fine, I would do a first water change and turn of the lights for 2 or 3 days (Blackout method).
Normally, this step does not solve the problem by itself, but helps to speed up the whole battle.
Again, cyano tends to disappear with time if all things are kept in order…
The last option, is to use chemiclean. It is way faster… but with some other things that you need to take into account or at least pay attention.
When I had cyano in the past, only once I used chemiclean (and it worked fine)… all the others times in a few weeks the problem was solved.
Let me know!
Cheers
