My journey using Chloroquine Phosphate begins...

Is it ok for me to run bio pellets while cp dosing? I believe this should be ok since it's just carbon dosing (as opposed to using active carbon to remove impurities). Also, running skimmer ok too?

Thanks!

Bio pellets should be fine; skimmer I would leave off. I'm not 100% sure about this, but it just seems logical to me that a skimmer would skim the medication out.
 
Thanks.

Now I'm thinking I should try and get my hands on/access to a uv spectrophotometer. Looks like there are a bunch of used ones on eBay for a few hundred bucks or perhaps I could have someone at the municipal water dept help me out. I'm surprised that in this thread I haven't seen others mention doing so. Am I missing something? Thanks
 
One more question. As mentioned, I will start the CP process in my DT, hopefully tomorrow. I will remove all corals and inverts, but not live rock and sand. Is there any risk that the LR/sand could cause a failure bc the tormonts could be buried in the sand and not exposed to the CP? I ask this totally separate and apart from the possibility that the rock/sand could throw things off by absorbing some of the medicine. i am not so worried about this later as (i) i can dose a little extra at the outset and (ii) i can get hold a spectrophotometer (hopefully) and check concentration.

thanks...
 
I read recently that CP is effective against flukes. Does anyone know if this is the case, and whether after 30 days in CP I can skip prazipro? My fish show no signs of flukes.
 
Does anyone have any tricks for removing anemones from rocks? I am fearful I won't be able to do get them off without killing them. I've tried ice on the foot and that hasn't worked for me...
 
Are you talking both meds at the same time?


Personally I would not dose them together as CP has some effect on internal functions (I believe it's liver function, but it's early and I don't have time to go back and find the info). Better to just extend the qt period and treat separately.

I used them both at the same time with no ill effects.
 
I am starting a CP regimen on my DT tonight. Will be removing all corals, not removing shrimp as I understand that they are ok with this medication. How about starfish? Specifically, I have a few black brittle stars and sand sifters. They may be really hard to remove, especially the bs's, but on the other hand i don't want them to die... nor do i want an ammonia spike, so i need to get this right... thanks for the help...
 
has anyone had a red algae or fungus grow in a CP treated tank?

I run CP continuously in my QT and have this red fuzzy stuff growing that appears to be light dependent, as it's growing only in the areas that receive light

Yes. Seeing it in my DT which is being treated with CP currently. Looks like cyano to me.
 
I also see a thin yellow-brown film in my QT after treating with CP. Appears as a light haze over the glass and powerhead. Probably again some sort of bacterial colony. I may do a scrape and look at it under the microscope.
 
I would remove all inverts and play it safe. I believe many has had dieoff of inverts with CP.

Yes, CP is quite toxic to inverts. I removed my cleaner shrimp, conchs, corals and as many Nassarius and Cerith snails as I could find. Got all of the Nassarius snails out, but I missed a large portion of my Cerith population since they bury themselves most of the time. After 24 hours, the remaining snails emerged from the sand and perished shortly thereafter.
 
I dosed tonight. The process went well, but with some hiccups. First, initially forgot to turn the UV off, but remembered 1 hour after dosing and turned it off immediately. Will 1 hour make a difference? Second, I had about 7 rock and mini-maxi anemones on the live rock that were impossible to get off. Last, I could not get my 3 brittle stars without breaking down the rock work so I had to leave them in. I got all of the corals and shrimp out and covered the outside of the tank with thick black garbage backs (how ironic given my failure to turn off the UV... ).

If I can only find someone local with a spectrophotometer then I can confirm the concentration of meds.

Last, the skimmer is off, but would it be ok to turn it on at a level low enough to prevent collection in the cup in order to aerate the water?

thx.
 
The UV could have removed a considerable portion of the CP in an hour's time. What is the turnover rate through your UV? I seem to recall that most UV manufacturers recommend 2x turnover per hour through the UV to remove protozoans. If you are running that flow rate, it's feasible that all of the CP was denatured in the process. This is pure conjecture on my part, however, since I don't know how quickly a typical UV sterilizer destroys CP.
 
yes, makes sense but it's real fuzzy/fluffy stuff, not the usual cyano, but agree probably it

I'm fairly convinced the fuzzy red film is some sort of cyano or related bacteria species. I did a water change this evening and siphoned a bunch of it off the rocks. It came off quickly in the same manner that cyano would.

Yes, I too had a breakout of two types of cyano after using CP in my DT. One red, one filamentous. Never got rid of it fully but learned a lot about cyano in the process. AM in the process of breaking up my tank (150g) to do a restart, partially due to this difficult to eradicate, phototrophic, phosphate-dependent cyano.
 
I will measure the uv rate this evening and do a partial redose. I believe the flow through the uv is only about 50 gph, which would be btw 1/4 and 1/3 of my volume.
