Hello, I am experiencing green water in my tank for the first time in many many years. Its a planted tank and had been running just fine for a long time. The green water started like 2 weeks ago after a period of medicating and gravel vac-ing (something I usually never do), so I feel like the cause of this is not an excess of nutrients since I was feeding very lightly or not at all. So no feeding for a week until today and the 2 weeks before that the feeding was very light compared to the usual.
Clearly there is some imbalance causing this, but what I'm wondering is, if I go back to treating everything in the usual way regarding feeding and cleaning, shouldn't the balance re-establish slowly?
Or any other suggestions? Keep in mind I am not in a hurry at all to get rid of this green water, I just want the end result to be clear water and would like to achieve it in the most natural way possible. -

Wow those fish are so pretty! I’ve never heard of them before. I’m going to do some research thank you!
have you ever kept them? Is there anything I should know about them?
(edit) one question I have is how many do you think I could get in a 40B tank?
Yes I have kept this combo in a 50gal. I started with 10 multies of various sizes and 8 juvinile cyps. Both species should breed no problem. Unfortunately I had a medication disaster and all died before this tank got to be the way I wanted it. The cyps had not fully colored up and had just started showing breeding behaviour when they all died.
You could start with a handful of each species in my opinion. The cyps are a bit large and boisterous for a 40gal so don't start with too many. Also because of how bad they ship, they can be quite expensive so keep that in mind. Last but not least about the cyps, their breeding is pretty cool. They spawn up top and turn around quickly to grab the eggs mid-water, they are mouthbrooders and their fry are very large when they hatch.
I wish you luck with your tank, I will definitely be trying this combo again myself later because I really want to see this setup mature and reach its full potential.

I would first consider if you need to heat your aquarium at all. Most of the fish we keep in the hobby do fine at room temp.

Cyprichromis leptosoma are a nice option as they stay close to the surface, opposite of the multies. They even breed up top as well, pretty cool. It is considered somewhat of a classic combo, multies and cyprichromis. The cyps are easy to care for but they don't ship well so if you order them from a considerable distance I would recommend ordering a few extra just in case.

I have some more thoughts. Does anyone know if keeping the fish outside makes them susceptible to parasites? As in, you have a parasite free fish that you put outside for the summer and it has parasites when you bring it back inside.
-
Thank you for that info @Torrey. I am not worried about that in my case, I have a massive insulated container built for fisheries and freezing temperatures. That is however indeed a very good thing to keep in mind.

I had whiteclouds last year and I can confirm that they stay active in cold water. One word of advice is, if its a big pond/tub you are going to want a LOT of them. Mine was 400liters/105gallons and I only had like 15 or 20 of them and never saw them, took me like 5 minutes just to find them.
P.S. A question to you who take part in summer tubbing, what do you do filtration/water movement wise?

Thank you @Cory, I will most likely go with a separate pond since I just got offered a second large tub for free. Im going to not empty the tub this year as well, It will be interesting to see the how it looks after winter.
Also, do you have sponge filters or some method of filtration or water movement in all of your tubs? Last year I went with no filtration or water movement at all, just plants.
-
Hey I have some more thoughts now that I have put some water in my tub and have started slowly getting it ready (squeezing a dirty sponge in it, pumping fertilizer, putting in plants and snails). I was hoping that you @Cory or anyone else with summer tubbing experience would have some suggestions for me.
The thing is that I also have some red cherry shrimp that I was planning on putting outside as well. But, I am wondering if there is any benefit to putting them outside? And would it be better to have them in a sepperate tub or in with the platies? I would love to get some pros and cons on those options. Mostly wondering if they will breed any more outside than they would in my tank, or grow up with better coloring, etc...
Another thing, are there any pros and cons to leaving water in the tubs between summers? This is my second summer doing this and at the end of last summer I emptied my tub completely, just wondering if there is any benefit to not doing that. Keep in mind that I live in Iceland and the water would most likely freeze solid at some point during winter.

With first year fish. Meaning they have only lived in aquariums prior. I was able to get them to about 58ish, before I got scared and brought them in. I think they can go lower especially after the fry have been raised outdoors for a generation or two.
Thank you sir for a quick and informative reply!

Hello guys n gals. I am planning on putting my variatus platies outside for the first time this summer. I am a heavy listener of the aquarium coop podcast and a video watcher and I remember @Cory talking about how cold these guys can go about a hundred times but I can't for the life of me remember how cold that was. I live in Iceland so this cold tolerance information is of great importance to me. Is there anyone who remembers or knows this information?
Thank you.

0KH isn't necessarily a problem, just know pH is free to swing, drastically at times, in a 0KH environment. As our water becomes more acidic, the BB can go dormant and stop the nitrogen cycle. Just be aware! Nitrates and other things, tannins and such, are acids. Also, if you have plants, during lights off, plants release CO². The CO² is then converted to carbonic acid. Test your pH an hour before lights on and see just how low it is.
I also keep a low KH. So once a week I check KH. I do small weekly water changes just to maintain the KH.
I imagine the problems you had were several things. 1, the meds changed the viscosity of the water lowering O². 2, 0KH could have allowed pH to drop in the high CO² environment. 3, the addition of the air stone may have caused a pH spike by addition of O². These possible rapid changes, coupled with sick fish, may have been enough to cause your cascading fish loss.
thanks, your answers have been really helpful and put things into perspective. I think I will have a better understanding on some things now moving forward.

Thank you a lot for the reply man, Yes I did not have an airstone the first 12 or so hours of the med time. I immediately put in an airstone as I realized the fish acting strange. And yes I do have 0KH, is that a problem? Btw its not really drastic ph swings going on, its actually pretty stable at that level, 5.5 or 6 ( sometimes at 6.5 but usually 5.5 or 6).
Actually I measured the water just now while writing this and to my surprise the kh was about 80 ish. Maybe more frequent waterchanges will help keep the ph and kh a bit higher (my tap water has ph about 6.5 and kh about 80). I can't think of anything acidic getting in the tank. -
And I just measured ammonia now and it is 0. But then again if ammonia was the problem I did already do a 80% waterchange yesterday. Also did a 6in1 test strip now and the parameters are the same except ph is up to 7 now. Also forgot to mention that ph has been going as low as 5.5 recently.
-
I measure the water every week. Ammonia and nitrite steady at 0.
Nitrates always 0 or <10
ph :6.5
gh: 0-50
kh 0-30
tc: 0
temp: 24c/75f

So, one of my tanks (classic guppies/snails/shrimp tank) had some clear parasite issues so I medicated it with paracleanse according to Aquarium Coop's directions and that is going very well. However I decided to medicate another tank I have because I have been using the same nets back and forth and some of the mollies there had clamped fins and another fish there had recently got half her tail bitten off so I figured the antibacterial and anti fungal wouldn't hurt so I hit it with the full classic trio, Marycin, ich-x and paracleanse. The morning after, the tank is super cloudy, fish gasping for air and my salvini male starts showing some extreme dying behaviour (sinking to the bottom, smashing into the substrate and decor, floating upside down, etc...). So I did a 80% waterchange and added an airstone but meanwhile the salvini male died. Has anyone had a similar experience with those meds? I think they might have maybe killed a lot of beneficial bacteria and/or depleted the water of oxygen.
Feeding Cat Food to Fish?

I know a lot of people who feed a high protein fish based cat food to their fish and they have a good experience, and its cheeper too. My fish didn't like it though. Protein film would be my only worry.
