Help My CRS Tank Please

i think the rocks might increase the ph?

[dnsfpl]

this is an office setup, in an air con room

what else can i use to lower the ph beside using peats?

thanks

bro.. wont the rain bar at the outlet cause the ohf box to overflow??

[dnsfpl]

nope in fact i am using something to slow down the output so that it will soak the biohome media

ur rocks seems to be granite if im not wrong.

granite not only increase ph but kh and gh as well which can kill crs in the long run.

gh for shrimps should be around 4 -6

kh wise.. can some expert comment on this?

based on Mizu World, Kurokinryu Stone does not affect water parameters and is safe for freshwater aquarium use.

hopefully its true

wierd.. even just by using a elbow to the output my water lvl in the output part already rise to the same lvl as my foam already.. wats ur pump flow rate?? and is it better to let the medias soak or let water flow through them quickly?

i hope u are right, because if your soil is brand new, your ph should not be so high unless:

1) your rocks leeched minerals which have increased your ph which means it has also increase your kh and gh as well.
2) you have done a huge wc.

most likely is option 1.

stay away from rocks for crs unless very sure that it wont do anything to your water.

to lower ph u can either use peat or else add driftwood. driftwood will lower ph when it leeches tannins into the water. peat and tannins will brown the water.

tannins can be removed with active carbon.

hope this helps.

i am using dolphin p708, not sure about the flow rate
used to have the same issue, but this diy rain bar pipe diameter is a lot bigger, with more and bigger holes too
moreover, i placed sponge inside the pump to slow down the flow

i am using 2kg of biohome in 1 tray, if not soak, the top potion will be wasted

i have yet to do any water change, will monitor the water parameter
what level of kh and gh will pose a danger to CRS?



is 4kg of soil enough to bring the ph of 40l of water down to 6.8?

thanks for your help

i m honestly not too sure. but i have heard that too high or low gh will cause molting difficulties. low gh will cause the shrimp not to have enough minerals to form shell after molting. too high i think will cause their shell to be too hard and not let them molt.

high kh wise.. im not too sure. but im very sure that kh and ph are co related. so high kh = high ph

unless you decrease ph solely using chemicals or co2.
