Where to maintain the alkalinity of the tank is a bit of a toss up. It really depends on what is in the tank. NSW
is anywhere between 1.5-3 mEq/l. However many find that keeping the alk
between 3-4 mEq/l is much more benificial to the overall health of the tank and less ceseptible (sp?) to swings in PH.
When maintaining alkalinity it is very important to balance the level against calcium. The two are very much linked together and control each other. If you have performed the Salifert test correctly and the alk
is 4.57, I would allow that to drop a bit. Closer to 4 would be fine. The balanced amount of Ca
would be slightly higher at about 425-440ppm.
Here is a great and easy to understand article
BTW, I only use Salifert. I find it the most reliable and easy to use without setting up the chem lab..
