2017年11月26日 · Very low Alk along with a high CO2 levels tested at night could produce a 7.6 pH level, but that's still pretty low for a normal tank. 7.6 would almost require a high volume calcium reactor pumping abnormally high C02 levels in the tank. Advising a skimmer to increase pH levels or water changes is just as dumb as chasing pH.

2013年3月22日 · The pH values observed in both the lesional and non-lesional skin of patients with AE are significantly higher (pH 5.90 ± 0.76 in lesional skin and pH 5.52 ± 0.64 in uninvolved skin) compared with healthy controls (pH 5.36 ± 0.5) (8).

2022年2月15日 · In low pH setups, to keep them active as long as possible, KH-less water is used, they could last as long as 3 yrs. In water with KH this happens sooner. If you add KH, alkaline buffer or baking soda, substrate should lose its buffering capacity even more soon, months maybe.

2015年11月30日 · Cosrx Low pH Good Morning Gel Cleanser is my top pick. It's incredibly gentle, no SLS or SLES, but manages to lather up really well with a foaming net, and gets my skin clean without stripping or drying it out even when it's in a very sensitive state due to tretinoin.

2018年10月20日 · ADA offers low pH substrates, Amazonia (in 6.0), Africana and Malaya (even lower), made specifically for aquarium use. Some EU shrimp keepers kept Taiwan bees shrimp in tanks with Akadama soil, below pH 6 too. From my experience with them, below pH 5.8 is not necessary, this should be enough for low pH animals.

2022年9月19日 · iUnik Centella Bubble Foaming Cleanser - they list as mildly acidic (6.2 pH). It is liquid and has the self-foaming pump dispenser. Haven’t tried it yet to compare, but the Pyunkang Yul Calming Low pH Foaming Cleanser also comes in a foaming dispenser (versus the PY Low pH Deep Cleansing Foam in tube).

The pH values obtained when measuring nonaqueous samples can only be used as relative measurements, to compare the acid-base qualities of similar solvents or to indicate when adjustments in pH are needed. The readings cannot be reported as actual pH values, since the pH scale is based on the relative acidity or alkalinity of water"

2014年6月28日 · Balance. Remove stains. Remove metals. That is the order. Simple answer if the pool pH is above 7.0 then move on to Alkalinity. If it is below the balance pH to get it above 7.0. Then do Alkalinity. Very low pH readings can have inflection. So test pH 3-4 hours after adjusting and then do Alkalinity once pH is at 7.0 tipping point.
