New 55g tank

This is a discussion on New 55g tank within the Cichlids forums, part of the Freshwater and Tropical Fish category; --> If my aquarium water is 6pH, if I add 6pH water, will the water stay the same pH or does the gH and kH ...

If my aquarium water is 6pH, if I add 6pH water, will the water stay the same pH or does the gH and kH and dH affect this too? If I use ro water and I add tap water until it is at 6 and add it to my tank what will happen? I am going to the LFS tomorrow and I am going to do a water test, I will tell you the gH and kH.

Let's get the numbers before we look at this Dylan. And I didn't respond to your previous post because i was hoping someone with knowledge of RO units would. Just so you know I'm not ignoring you. B.

:) Dont worry, i didnt think you were ignoring me. When I go to the LFS tomorrow, I will ask them the parameters of the water they keep their discus in and the same for the rams, cardinals and cories. Since the discus are most likely tank raised (I will ask) they can easily become accustomed to more neutral pH. I truly dont know what my pH is, the lowest number my crappy pool water test has is 7.2, so my water might actually be lower than that. I am hoping the kH is relatively low. If the water is only 7.0 or about that, and my water is generally soft, I might just try to lower the pH with peat moss, hoping that there arent any buffers in my tank that wouldnt allow the peat to work. Once I have the readings of my water and the lfss water, i will be able to make an appropriate decision as to what is the best way that I could comfortably keep discus, or if I should, spare myself the effort and go with angelfish and blackskirt tetras (not very likely :)

Thanks,
-Dylan.

So, i went to the LFS and they werent doing water tests anymore so the guy told me to buy a water testing kit, which was like 50$ so I said no. He didnt know what the water parameters of the discus tanks were because the discus and saltwater guy wasnt at work that day. I ended up only buying more plants for my 29 and 4 amano (or yamato) shrimp for my 10 gal. I will have to go to another store to test my water and I will go to that store when mr.discus is there to ask for advice since my water is probably similar if not the same as their tap water. They also had tests for only pH or only gh/kh, only nitrates etc. but they were like 15$ each and I didnt want to buy all of those different things. I will have to report back to you guys once I get my water parameters all sorted out :)

By the way, I might have made this LFS seem kind of bad but they are one of the best pet stores I have ever seen, they had like 50+ species of plecos (no exageration) every possible colour of guppie, every tetra known to man, oscars, arrowanas and plecos bigger than my cat, every plant I could think of, crazy saltwater fish and even seahorses at some times. they also have a knowlegable staff of lke 20 people. Although the prices go up due to the good service and expertises :( BTW it was a bit discouragin to see that the least expensive juvenile discus was 49.99$ and the most expensive was over 100$. Also I saw some dennisoni barbs that I once wanted, but they were 12$ a piece!!! Sterbai cories were 7.00$ each. I know other privately owned small stores that have them for like 2$ each and cardinal tetras for 1$ each and they arent of any lower quality ;) I hope you enjoyed my little summary of yesterday :)

thank you

-Dylan.

Just a follow-up on the API gadet, note Harri's post #10 in this thread:

This may be worth looking at.

I read that entire thread I think that would be a very good option for this tank. I know my tap water is around 7-7.2 and around 100-125ppm alkalinity and slightly less than 200ppm total hardness, I dont know how or if that translates to degrees in gH and kH. I am pretty sure my water is medium to soft ish. The concept is retty similar to an RO unit with that API gadget. I have relatively pure water that is generally neutral and extremely soft, therefore, I can add as much of my tap water to it, to attain my desired pH, that I could then safely add to my aquarium. I was also reading more about peat moss and I read somewhere that it acts also as a buffer and it softens the water, acidifies the water and maintains the water at a certain softness and hardness. If the peat moss works as a buffer couldnt I just add my dechlorinized tap water and the peat moss would automatically absorb the minerals and keep my water at lets say 6pH. What is the range of hardness discus genrally tolerate (in ppm)?

79-86 F, KH 1-3, pH 6.1-7.5

Let me check if there is a way to convert it to ppms

I believe it would be 17.9 - 53.7 ppms

6.1 to 7.5? I thought discus liked 5.5 to 7.0? I would definately have to lower the kH for discus.

To convert ppm to dGH and vice versa, 17.8 is the number you use. You divide ppm by 17.8 to get the dGH, or you multiply the dGH by 17.8 to get ppm. So in your case Dylan, 200ppm of GH is 11 dGH. That is medium hard, so lowering it with the API might be sufficient.

The optimum pH for discus would be 4.2 to 6.2 but others say they will adapt to the low 7's though unlikely to spawn. Hardness less than 3 dGH is preferred, and I will leave it to the discus experts to suggest possible higher values. If cardinals are still in the plan, I would definitely have the pH below 7 and reducing the hardness is certainly required for them.

Peat works to soften water by releasing tannins. As I think was noted before, it wears out and needs replacing; the life of the peat would depend upon the hardness and the water volume, and having never used this I couldn't say what amounts that might be required.

As far as those fish prices are concerned, those do seem a bit high with the notable exception of the Denison's Barbs. $12 a piece is a very good deal for those, as I usually see them for about $20 each for small fish (2-3") and $30 for larger specimens (5" or so).
