Vet Q & A
Is beach sand safe for my freshwater fish tank after cleaning?
You can, however it isn't as simple as collecting a few bucketsful and dumping them in your tank. You will need to properly clean the sand to remove impurities and parasites. This involves soaking the sand, water changes, more soaking amd more water changes. It may take several weeks. There are videos you can watch on the bigger video hosting sites. It is much easier, and safer for your fish, to buy sand that has been prepared already.

Vet Q & A
Is plant fertilizer safe for fish? What do I need for a planted tank?
When used as instructed, plant nutrients and fertilizers designed specifically for aquarium plants will not harm aquarium fish. Allow new aquarium plants to settle and establish themselves before adding any fertilizers. Use aquarium plant substrates such as CaribSea Eco-Complete Plant Substrate http://www.drsfostersmith.com/product/prod_display.cfm?pcatid=9087 to get your plants established faster. Seachem Flourish Advance Natural Phytohormone Supplement http://www.drsfostersmith.com/product/prod_display.cfm?pcatid=33890 will help stimulate root growth vital for overall plants health. Even though you have plants with low to moderate light requirements, be sure to use aquarium light specifically designed for planted aquarium use (sometimes called plant lights) and have the lights on between 10 and 12 hours a day. You may need to adjust the photoperiod (the amount of time the light is on) depending on how your plants are doing and to prevent unwanted nuisance algae growth.

Is calcium sand safe for my reptile, or should I use eco earth?
Although some expert may disagree, as long as Ash isn't ingesting the calcium sand then you can continue to use it. Calcium sand is not the same as play sand which would not be recommended. If you don't want to use calcium sand, consider slate, reptile carpet or even paper towels for easy cleaning.

New to fish? What are the easiest fish and tank size for beginners?
Guppies or Neons are excellent "starter" fish. Care is simple and they are inexpensive. A standard 10 gallon tank is recommended to start. Most people don' t realize the amount of "work" needed to maintain a tank. Filter maintenance, monitoring water chemistry, water changes, monitoring fish health and providing a balanced diet are just a few items that need regular attention to keep a tank thriving. Even though fish aren't as cuddly as cats and dogs, they do have their own personalities and even respond to their owners, especially at feeding time! Studies have shown that simply watching fish in a tank can lead to a reduction in both heart rate and blood pressure. It is quite relaxing.

Vet Q & A
What's the best way to maintain stable pH in a discus aquarium?
Thanks for reaching out. There are many products available in pet stores for either adjusting pH up or down. Adding a buffer as a substrate (dolomite) could help regulate also. Maintaining water quality is obviously very important. Good luck.
