Hi,
yes, temperature is more important for CRS, I'm using normal lapis sand, no problem for my C grade CRS. Probably better CRS grades rerquire better sand.
Can CRS strive in my present stable Cherry tank which is using inert black quartz instead of the famous ada.
I think temp seems to be a more important parameter then the soil, is it right?

CRS can survive in most gravel. The reason why people use ADA is so that they can keep the PH low- around 6 plus, which is ideal for CRS. ADA is very rich in nutrients and you must be careful or you can easily have an algae problem on your hands.
I'm using Dennerle Black Quartz & CRS are fine with them. So far, after my tank has stabilised, any new additions survive very well.

Hi Ivan and Matt
To counter the PH problem as lapis sand and black quartx cant overcome, what do you do to lower your PH for your CRS? I presume both guys have chiller ?
Regards
I'm using lapis gravel with CO2. Before injecting CO2 pH registered is around 6.9. Inject CO2 till 6.6. But I'm going to redo my tank with ADA and dennerle quartz for better colour contrast.
God will make a way, where there seems to be no way
ADA soil used only for lowering the PH. however a lot of hobbyist not using ADA soil also doing well
I used gravel only with CO2, don't know PH level, maintain temp at 25-26 without chiller. After tank setup for 3 days, I introduced 3 C grade CRS (1 died on 2nd day, don't think was caused by my tank, it was not very active at LFS when I brought, but it was a C+ grade, so I took the risk).
I week later, I brought 6 A grade CRS(actually 1 is B grade, given FOC), and following week 2 A+ grade diamond. All are well so far. To me water quality and temp are most important.
They do well with bare tank and with big pieces of drift wood. Tried this type of setup when keeping lower grade, not to sure those higher grade one, known to be more fragil can do well in such setup.

25-26 without chiller ? how you do it ? please shareOriginally Posted by boonpeiu

looks like option is Co2 or ada to condition the water to right ph. ketapang makes water brownish...that option is out as looks really ugly.
Hi skysky,
All my CRS tanks are in office which average temperature is around 25 deg.
Mine is a 2x1x1.5 ft tank, setup in my living room coolest spot. It was 29 deg, then I added a fan (fr C328 (China brand), actually 6 small fans inside) blown from back to front, it drop 3 deg to 26(27 on hot noon), impressive!
Next, I place my Ehiem 2232 into a styloform box, add water in box and used 1.5l soft drink bottle to make ice and place into the box. 2 bottles can maintain between 24 to 26 till evening. If I am at home, I will make one change in afternoon, else will be one change in evening. I know many will find it tedious, but I do not want to pay for a high electrical bill. This method work very well as it will not drop temp suddenly compare to place ice bottle directly into the tank.
Just my cheap way for shrimp tank.
Oh! Another thing to share, my water is from a 6 filtering system suitable for direct drinking. I do not need to condition water over night, I always used a hose to add water directly.
Yes I have chiller and I run on high cO2 to push down the pH. My pH level right now is around 6.4

can i throw a bag of ada soil (wrap in platic mesh) into the already stable tank to lower the ph instead of rescaping my present tank?
Never create what you can't control
New ADA soil will release ammonia into the water during the first few weeks. So it's definitely not advisable.
Also, rescaping with shrimps in the tank may put them at risk. Many aquarists reported shrimp deaths after rescaping. So this is something you may want to consider before doing anything.
nope, not going to rescape for sure. how about i get those 2nd hand ada that has been used for few months ?

No idea, I am not a user of ADA soil. I believe that if it is not used for too long, then it may still have the buffering properties. See what the actual users have to say.
the best is to test the water everytime you do a major rescape. Like in your case changing the base gravel
