G&D's Foray Into a 90G Tank (Take One)

The key thing to remember is to keep your tank oxygenated during the treatment period of 2 days. Either use an air stone and pump or you can keep your skimmer on but take off your skimmer cup to allow it to overflow into the sump. If you keep your skimmer on and allow it to overflow you may get lots of microbubbles into the tank and it'll look bad for a couple of days but it'll all clear up once the treatment period ends and you do your recovery water changes at the end of the 48 hours. I did two consecutive 20% water changes then put my skimmer cup back on.

Round Two has begun! I purchased some Chemiclean this afternoon and treated the tank this evening. I turned off the carbon and pulled the cup off the skimmer as suggested by Kien. On Thursday evening I will do a 20% wc and then wait to see if I've won or if it goes to Round Three!

As I continue the battle with the bit of cyano that I have had in my tank I tried the Chemiclean as recommended (thanks Kein!). So far I have been very happy with the results. I treated the tank with Chemiclean last Tuesday and 48 hours later did a water change. The tank now looks great. I plan to do another water change tonight or tomorrow. And I will be keeping a close watch to see if the cyano begins to return. The challenge now is that I have been having a problem with the skimmer. When I turned it back on after the treatment it was "boiling over" and I have been trying to redial it in ever since.

Below are pictures showing the progress with the treatment.

Looking good and glad to hear that you are winning the cyano battle.

Glad to see you're winning! This is typical and for the reason I did 3 20% water changes. After the third water change my skimmer started to get back to normal. Still not quite where it was prior to the treatment but it at least stopped boiling over to a point where I could put the skimmer cup back on. A couple of days after the last water change my skimmer was back to normal. You just have to give the system time to settle back down.

Also, did you put in some carbon into your sump to help clear up the meds? You can get a media sock and throw in some extra carbon into it and place it in your sump. I did this as well for a few days.

Thanks for the advice. The skimmer is working a bit better today. Regarding adding carbon - we are running a GFO / Carbon reactor - how often should they be changed out? Would adding some carbon to a filter sock be effective?

Thanks

A while ago we purchased a second Percula to replace the one that dissapeared in the tank (still have no idea what happened). It is close to half the size of the first one and they have paired up well with no problems. Below are a few pics of the Percs. Also I added a few other pictures that I took last night.

I normally run carbon and gfo too and typically change then out once a month. However, when I did my chemi clean treatment I added an extra bag of carbon (in a media bag dropped into my sump) to help take out the meds. I replaced my carbon in my carbon reactor on day 7 after treatment and took out my extra carbon bag.

I don't have any experience running carbon in a filter sock. I personally wouldn't do that tho as my carbon would probably get lodged in my sock fibers and/or overflow into my sump if/when my sock overflowed.

Thanks Kien - this makes sense to me. I appreciate the advice.
