Will this work? Yes
Is this preferable to using Ph UP? prefered by whom?
Won't it hurt the fish after he puts them in the tank? No
I did a GOOGLE search on BAKING SODA AQUARIUM
and came up with over 3300 links.
I'll narrow it down for you;
Baking soda is great to increase your pH but it won't hold it up there forever. Epsom Salts not only increases the pH a bit, but I think it also helps fish digest and pass their foods, it may even help prevent the dreaded "Malawian Bloat." Rock Salt increases the saline and also help reduce the possibility of ich. Soda ash will dramatically raise your pH and will keep it there, however you must be careful with Soda Ash, it can literally burn you and your fish. There are also several commercial water additives available on the market, but you still have to know what your water conditions are before knowing how much to add.
I wouldn't be surprized if Baking Soda (aka sodium bicarbonate
) is one of the main indredients in Ph UP.
WAY OFF TOPIC>>>
For my Hot Tub, the Ph PLUS is sodium bicarbonate and the Ph DOWN is hydrochloric acid. I just buy the generic stuff 'cause it's way cheaper.
The "Filter Free" (Hot Tub filter cleaner) is a TSP (TriSodium Phosphate) solution. If I were to buy a 1 year supply it would cost $120. However, I can make the same amount using TSP and water for $1.50.
I'd rather spend the additional $118.50 on my fishies.
Just my opinion.
