Ph For Bristlenose?

[tom130691]

my ph is around 8 now my cycle has come to a end, it was a fair bit lower before anyway i have got a me a bristlenose today will it be ok or will i have to lower the ph abit ?

will water changes lower ph if my tap water has a lower ph?

the ph will drop slowly, bristlenoses are pretty hardy and as long as you dont change is drastically and suddenly they will cope with small changes faily well, have you got lots of plants and bogwood, the more you add the lower the ph will go within reason, if the ph in your tap is lower than maybe do a few water changes over a couple of weeks to bring it down. di

My tank sit around a PH of 8 and my plecs seem quite happy. Added some Mopani wood last week so hopefully that should pull it down towards 7

yes i have 3-4 small plants and 3-4 taller ones plus a big piece of bog wood
i will be doing around 50% changes weekly for my rainbows anyway

should bring it down nicely, id be warey of doing 50%, i was always told no more that 30-40% at any one time and 50% in an emergency as this will reduce the amount of beneficial bacteria in the tank, what does anyone else thing, you might have to do a new post to get the experinced members to answer a water change question, its just what ive been told you might want to check it out first. di

this is what is needed for the rainbow fish mate they have to have very clean water
as for bacterial they cling to thinks such as gravel n media's ect not many are actually in the water otherwise you would never be able to do a fish in cycle witch i have just done
as long as you dechlorinate the water and have it a similar temp to the tank its fine

Not sure exactly what you mean that your PH is usually lower than what it is now?, after the cycle finished did you do a huge water change to remove the high levels of nitrate?, this would have lowered your ph back to or closer to the original tap water. If the PH is rising still after then you obviously have something within the tank making it rise again. You PH will bounce around in this case everytime you do a largish water change and in theory that could pose a bigger problem than a stable ph of 8

The plec will be fine in a PH of 8, they usually prefer it in the lower 70's but that's more important if you was introducing a wild caught species which wouldnt be used to any sort of PH bounce or any extreme bounce anyways.

my nitrates never exceeded 20ppm as i have plants in the tank it varries between 10-20 usualy there fore i havent done a large change since my last nitrite levels
as for the ph it was around 7.6 about one week ago when the tank was cycling and i was doing the larger changes

perhaps initially. but the tank tends to "buffer" back to the common reading. to be honest, the best PH to keep your fish in is, the one you get from your tap. after the tank has settled (buffered). messin with PH, is a world of pain. often not worth suffering.

the forum consensus is, water changes of any size are fine. its true, of course, that very large water changes may stress your fish, which is another question. but, from the water point of view, no harm can come, of it. and there is no, significant, amount of "beneficial" bacteria in the water. any, there is, will be in the substrate and on the bio film. neither of which sufferers because of water changes.
