Ok here s the deal I m gettin away from the idea of a 2 gallon and now have a 15 gal , to set this tank for salt should I buy live sand and live rock or can I skip the live sand . Now do I put tap water and add salt and measure the salinity with a hydrometer ?? The 15 gal is used with a hob filter and fluorescent 1 foot bulb. Help I need steps to get this going 🐬🐬😎👍
