I switched to aquaforest salt a few months ago, had trouble keeping alk steady. Have to dose new salt, I measure to 1.025 salinity, mixed the bag and tested it with red sea kit, popped up as 5.6 Talked to fish store guy and he still recommends that one over the others so threw that bag out and tried a new bag and picked up an aquaforest kit which has a sample. Sample water included measured correct with aquaforest test kit but again the salt itself this time is measuring 6.7, red sea test kit showed 6.4, with the sample test showing perfectly I find it difficult to believe the tests are all way out of wack, but the salt itself is supposed to be tested on each batch. Magnesium was testing at 1430, calcium was 440 which was the only correct number. Is this a testing problem or a salt problem?
What other salts don't have crazy high alk? Most of the other ones I saw are 11-12 so when I do 20% water changes on my 30 gallon tank it spikes alk and makes things angry
