[quote="blueblue"]Hi minicooper:
1. The caves come from Germany, please search my old posts for some details if you wish.
2. My tank's pH is fixed at 7. Zebra pleco loves neutral
and SOFT water. Adding coral is NOT a good idea as water will become hard. The way to lower pH is to have more frequent water changes and better filtration system... Adding pH buffer (chemicals) can help, too.
i have three filters for them:
a. External.
b. Internal Hydor R20
c. Bottom tubes with power head (Eden).
Thz for ur info..
Wow, is from Germany.. too far for me.. maybe i think about other replacement..maybe DIY.... Actually i m using a a small ceramic vase 18 cm x 3.5 cmx 3.5cm.but the bottom is not completly sealed therefore i may use some hot gun glue to seal it up!!
With those Filters how often u need to change water? and how much each time?
I am using 2 filter for them.
one AA upper external and AA power head with filter.I like A A Stuff...
I m using bare tank method now. there4 I think is better put some woods in the tank to let those fellows to hide. and graze on it... only problem is the PH. always below 7.
But mainly some of those fellows were kept with my crayfish tanks b4. those tanks' PH some time will drop to 5.5 (orange level) coz always forgot to change water daily they still look happy with it and eat alot. only one thing is they grow slowly..... !!
I have seen some article recentlyt mention that PH not really affect the fish too much ( of coz not too extremly low nor high PH).. only the amonia and N3 N4 will do harm to the fish... Have u come across those articles?
