got it
, I have no trust in any test strips for a fish tank. big fan of API master fresh water test kit. no need to test every week, just test to find out what your water changes need to be, then test from time to time to make sure nothing has changed. like growing fish, new fish added, feeding habits changed, wither more food, or a change in brand or what you feed. and maintenance on your canister filters less they dirty and you running a nitrogen bomb.
Testing that often seems very much overkill to me.
I have a well and know my starting water chemistry is VERY POOR insofar as Nitrates. Just over a handful of miles down the road (Finksburg, MD.) they are required to post warning signs in public facilities stating the high (15ppm) Nitrate level and advisory to young children.
Smallwood runs just under half of that (right out of the wells tapped into the water table!)
I agree, and it is imperative to get a firm base on your water chemistry by initially doing frequent water testing. I recorded my test result on my 20 - 30 tanks in an excel spread sheet rather than a notepad. Each columns can be defined with conditional formatting to alert you to any number of variables (Not only simple thresholds).
Each individual tank had its own tab in the spread sheet where the conditional formatting was depending on the stock in each different tank. A column was setup for PH, Am, Ni, Na, GH/KH & temp. I often set different color shading alerts in each column for Upper limit thresholds, % change from previous test reading and continuing directional change trends.
After around 18 months of close monitoring, it became almost like clockwork on the extreme majority of tanks with no alerts from my preloaded conditional formatting on any tank below 20 gallons.
5G, 10G & 20G's had far more variance than 40's, and I found the larger the tank the less the variance in parameters, and again NO upper threshold alerts after setting the parms.
I am like the 4th person in this thread seriously interested in an accurate quick dip test strip. I would use these religiously!!!!!!!!
I will no longer do a TEN to twenty minute water test on 5G to 20G tanks to avoid (unnecessary WC's) when it takes TWO to FIVE minutes to do a 100% water change on them.
Again I stress (WELL WATER)
ZERO chlorine (EVER!)
ZERO water bill (EVER!)
Fish Water ==> Siphon + 100' 3/8" drain hose ==> outdoor gardens = great daily food plants and cleanest water possible for fish. (No testing involved, and less than half the time spent.)
Shake a test tube vigorously up and down for five minutes on four separate water parameter tests and you are playing with yo self
