Understanding alkalinity and ph---the easy way.

Posted 07/04/2017 at 09:11 AM by Sk8r

"In chemistry, pH (potential of hydrogen) is a numeric scale used to specify the acidity or basicity of an aqueous solution."---wiki. Ie, is your water acidic like lemon juice---or alkaline like a desert pool?
On that scale, battery acid (ph of 1) and drain cleaner (ph of 12)---both extremes can burn.
Your tank should be between 7.9 and 9 for the comfort of fishy skin and gills.

BUT--- ph in a marine tank wanders all over the map during a given day. Pretty...

[a companion to the cyano thread]

DO I need a...[skimmer, filter, ro/di, reactor, ATO, etc.]

Posted 09/12/2014 at 12:05 PM by Sk8r

Understand, you can run a very simple kind of 30 gal tank with nothing but a pump, a heater, live rock, regular tank light, and a Penguin filter, with a 'fill line' drawn on the glass to help you top off accurately with ro water from the supermarket. This is the ancient method. It will support a few crustaceans and snails and a couple of very small gobies or blennies or dartfish.
