No clue on the Gh/Kh...do I need a different test kit for that? I know I will have to upgrade the tank eventually, but I just can't do it right away. So for now my goal is to get the tank cycled and keep the water quality good. I am doing the water changes and also adding the water conditioner so the ammonia should not be harmful and the fish are extremely happy. So at present, my only concern is getting the pH levels correct so the cycle can complete.


Thanks again!

Yes there is a GH/KH kit made by API which is a good choice.

I'm actually quite envious of your PH, it's great for certain species of dwarf shrimps!

The low PH is your friend right now, not in cycling, but in keeping the feeshies alive :D

I dont recommend working against your water. But if you have to, it is likely you will have to premix your water and let it sit for a while before you use it :( In the initial stages this will likely lead to buckets and buckets of water prepared in advance due to the frequency of water changes needed >.<

Some one else might have a better method, I only keep pico tanks, so any water changes larger than a gallon is pretty much beyond my wisdom....


Another thought... is there any way for you to return the goldfish until you manage to figure out your water parameters and cycling issues and then cycle the tank first? I think this way it would be less stressful on you and the fish :)

no, I cannot return the goldfish unfortunately. So i did a 25% water change this evening and the pH levels are now 6.8. Is this a good level for cycling?

Aww... Poor feeshies :(

Hallyx is knowledgeable on all aspects of cycling, he can help you with that :)

Maybe you should try one of the cycling products, I think Tetra safestart is one of the few that is known to work

I was able to cycle my tank at a ph of 6.4/6.8 with super low kh/gh. I can't tell you how long it took, I never kept records, but one week I was reading 8ppm ammonia and a few weeks later I was at 0. I did 25% or larger daily water changes and had a ton of fast growing stem plants (the fancies might eat those, but would floating plants like frogbit work? I don't know if they would mouth those or not.)

Keepsmiling gave a lot of good advice in post #10. As long as you're reading ~7.0 pH, you'll get a strong, stable cycle. You can slowly raise you KH with crushed coral or seashells. As Carole says, running a sponge filter will usually raise your pH by oxygenating the water. A sponge filter also provides a large volume for the bacteria to colonize.

Tetra Safestart is an easily available bacteria-in-a-bottle. Make sure it's fresh (check the sell-by date). Fresh API Quickstart, ATM Colony have been reported to work well. Seachem Stability works for some keepers. Dr Tim's One-and-Only is arguably the best, but expensive.

It's probably easier to do more smaller pwc's than it is to age lots of water to allow your refill pH to go down enough to not pH shock your fish. For example, doing a 50% pwc with refill >1.0 pH above your tank pH is pushing it. As long as you don't raise the pH much more than 0.5pH all at once, they'll be OK. Even Bettas can handle that. And goldies are tough.

Goldfish will generally begin to bottom sit at a pH of 6 this is about the bottom of their tolerance. I generally would like to see a kH of 100 ppm minimum with goldfish to maintain a stable pH. Being a water purist I almost never say this, I would add crushed coral to filter to stabilize the pH.

Can you explain in detail about adding the crushed coral? I have a TopFin Power10 filter that came with the tank. The filter cartridges are supposed to be replaced every 3-4 weeks. I will be able to add the crushed coral into those cartridges?

Also just to comment on their behavior so far...no bottom sitting. They are very active swimmers.

Thanks

I have read many good things about the Tetra Safestart and think that I may go that route. But one question is will a low pH impact the products performance?

Thanks
