So basically my elasticity supply is on a key metre! I recently added a couple more betta totaling my number to 7. Anyways was out all day and when I got in my power was off! I have no way of knowing for how long! I went to the pet shop and bought more dechlorinator as my guess is more water changes would be needed and a special offer was on that and filter booster which said also recommended for after a power cut so I bought it! The product is love fish filter boost and has no exact description of the bacteria! I've only added one dose! Would any one recommend using it or ditch it?
