Can I use this on bettas, or do I have to use bettafix only?

Absolutely you can use it on bettas. Just make sure the dosage is right for the amount of water the betta is in.

You can add fish right away, but not many. I would recommend using Prime for your water changes. This product will speed up the cycle, but the fish should still be added slowly.

It did cause slight PH fluctuations but what I did was keep a very close eye on my fish. I was ready to go if something happened but for me the shifts in PH were very very minor. I ran an air stone at night to desaturate excess Co2 since plants don't use it at night. Without taking any responsibility if you lose fish, I think you are safe. I keep ghost shrimp and a male Betta in a 20 gallon and they are fine. If you are maintaining all of your other parameters and your tank is healthy I don't believe you would have a PH imbalance large enough to do harm. Just make sure you use a test kit for a while when you start using the Co2. Test kits are a very important tool. I will post a picture of my tank using this product.

I haven't had n e problem with this product & have been using it for a while. It really isn't needed, unless your not doing frequent water changes. I do my normal water changes & use this when I've been lazy & haven't gotten around to doing a water change for a while. If it helps, next time pour it into or near the filter so it can get broken down quicker. Or mix it into what ever water your going to add to your tank if your adding it during a water change.

the filter is in that black elongated tubing, it doesn't go down into the gravel. This only fliters the the water on top of the gravel. This fishtank only shows for glo fish. It only has a blue/black light, so it won't show up regular fish. I didn't know this and bought this for my betta fish.

I don't use a standard filter on these tanks (we have 5 betta fish). Instead, I use a disc bubbler under the gravel for aeration in each one. Love these tanks and their design, but not too happy with Amazon shipping b/c all of the tanks came with at least one divider broken or cracked. Also, don't like the solid glass lids. In fact, I was leaving those off entirely at first, but one of our bettas leaped out of the water while I was at work. I didn't even know a fish would or could do that! So hubby made me some wire mesh covers for them. But now I'm rambling, sorry. If you want to use a filter, I'd get the smallest one you can find. I think they do make filters for 5 gallons and under. Again, I haven't had to use a filter. I use a disc bubbler, and lay it on top of a cottony pouch that has charcoal in it. I have to change the charcoal out only about once every three months. Bettas are so clean and if you don't overfeed, their tanks stay nice for a long, long time. Love the idea and design of these tanks, that's why all my bettas are in them, but see preceding for adjustments we've made over time. Hope this helps.

No, it is not recommended to do that at all. This will cause the filter to not function properly. You have 3 levels in the middle for your choice of media. Fluval has recommendations for the proper setup which can be fine tuned by the end user since every tank is different.

You don't have to wait at all if you're worried about harming fish, but if you're trying to cycle a new tank, this product didn't work at all for me. I finally got mine to cycle with NutraFin Cycle Biofilter supplement.

No, it is not adjustable. You could slow down the flow by stuffing extra filter materials or partly blocking the output. It would be too much for a betta in a small tank, like a 5G. You might be able to use it in a 10G, specially if you lift the spray bar above the water level -- more aeration, less current. But if you have a smaller tank for your betta (like most owners), this would not be your first choice of filters.

I love melafix. I have Koi and Goldfish that live outside in a 130 gal pond. I use it with pimafix to get rid of fungus which is what yours might be. You can use them both to make sure to wipe out everything. Follow directions to the letter. Also the water will get foamy which is normal and don't treat more than 7 days max. Do a 25% water change at end of treatment.

I wouldn't use this for anything other than 1 betta. It's too small and doesn't have a filter.

I have a betta in a 5.5 gallon tank, and honestly this is the best bang for your buck. I tried going the cheap route before i knew much, and got just the ammonia kit. But later just ended up buying the whole thing. This is cheaper in the long run compared to some like 5 $ kit that has 15 strips.

I actually got a betta heater that suctions to the side of this tank without an issue. I love this tank. I would, however, invest in a different "filter" as it doesn't come with a filter but an air stone. I found a small tank filter at my local pet store. The LED light is amazing, several colors and a couple effects on it. All in all my Betta and I love this tank :)

By itself I don't believe it's suitable because it has a strong filter, however if you do what I did it's suitable, I have two FLUVAL tanks with a betta each , and I have no problems, both are cycled and work well. What I did was I took a black filter sponge about two inches square ( you can by them at a fish store , you don't need to cut from the ones that come with the tank) and I pocked a whole in it , about an inch through ( not all the way through) then i inserted the tip of the white tube that is connected to the filter, I tied the tube to the back side grid tank ( wher the biological media is located ) It has helped slow down the flow and my bettas are happy and thriving.

I would not do that. Not sure how this stuff affects ph etc... Use aquarium specific materials.

Yes, it would work fine with a single betta. I like the fact that they are adjustable, look good, and do the job. I have had a pair of them running on a 3 way divided 10g tank flawlessly for a year now. You can even add more media if you like. I fitted a bit of sponge to the intake.

I don't think that you can. I am using it in a 75 gallon tank with a fluval fx5 filter. It is not performing like I had hoped. By the way, it has a very funky smell (new out of the container too).
