Iíve had my tank set up with fluval stratum, drift wood and plants for 6 months now. I was using tap water and had my ph at 6.3 Kh 0.5 gh 5. Iíve recently switched to ro water using gh only to reconstitute to the same tds I have in my tank. I also bought a more expensive pen to monitor parameters. (All calibrated) now I have a range of ph results to choose from
Old pen 6
New pen 5.8
API test 6 ish... definitely a bit of green in there, if I add acid is goes much more yellow.
I have about 60 shrimp in there. The CRS seem to be breeding fine , but the numbers of my RCS seem to be dropping.
Iím assuming my ph is to low for the RCS to thrive. And in what Iíve read the CRS can only tolerate a pH down to 6.2
Iím now concerned that having no kH in there is allowing bigger ph swings. I was considering using some kH in my reconstituted water to try and have more buffering. Or should I remove my driftwood?
Confused about whether to just leave it be or to change something.
"Fancy" shrimp can thrive in ~5 pH and potentially even lower! I have YKK's breeding in a tank that, when originally set up, was at 5.5 pH, although I'm not sure on current pH, but it's still acidic.
The pH is *NOT* an issue for your Crystals.
Would not recommend adding KH to the tank. If you raise parameters too much and have thriving Neos, then your Crystals will likely suffer. *UNLESS* they are "low end" crystals, that may live in slightly higher parameters. If they are high end crystals, such as PRL, then you definitely do not want higher parameters.

My stratum got old and was time to change so i decided to not use active substrate because cleaning and changing it was a nightmare. I went ahead and redid my tank a 2 months ago with regular shrimp substrate that i use for my neos by aqueon that doesnt buffer at all. Im still using RO water with bee shrimp mineral to get tds of 120. The problem starts when i went to check my ph in the tank. My ph is 5.2. The ph meter is fully calibrated so i know it is accurate. I had a lot of almond leaves and cones in the tank so i removed it but that didnt really make a difference. My question is , is 5.2 ph too low for cystral reds? My objective is to get them to breed. I dont understand why my ph is lower now vs what it was with the buffering substrate i was using which was meant to lower my ph. Should i leave it be or raise my ph to 6.2. Right now bee mineral doesnt have kh so i was thinking if i mix salty shrimp gh kh with bee shrimp mineral Gh , 60 tds each, it will give me a kh of 1, gh of 5 , and tds of 120 before i put the water in the tank and the kh shoul help to stabilize my ph around 6 . What do you think? What should i do , leave it alone or add some kh? Why is my ph lower now then i was with active substrate when i didnt change any thing else i was doing. Please help!
An alternative is to get either a HOB or HOB breeder tank and simply put substrate in there and have that circulate through the tank. When it's time to switch out the substrate, you simply remove HOB, replace substrate, put back on the tank.
The pH is *FINE* for your shrimp, too! Lack of breeding could be due to parameters, diet, age, substrate or other factors. Were they breeding on Fluval?
What is the "shrimp substrate" you are referring to? What brand?
How long have you had the crystals for?
