AlgaeControl^™

No, this is for ponds only. We do make an Algae Control for aquariums, however. http://www.tetra-fish.com/products/water-care/algae-control.aspx. BREX

First, make sure you have the aquarium formula, and not the pond one. Assuming you do, you would use 1/10 of a teaspoon, 1 ml or about 2 drops. BREX

Not that is safe for snails. Fish, yes, snails, no. Algae can be controlled with proper maintenance and stocking of the tank. BREX

We have not tested this product on these species, so we recommend keeping them away from the product in its concentrated form. In a diluted form (in the pond), keep animals away for several hours, to make sure it is fully diluted. BREX

Not if you have any fish life, etc. The pond has to have been in operation at least three months. Green water is the number one complaint of all pond owners. There are three options for controlling it: 1. using chemicals every week or two throughout the warm part of the year 2. installing a uv light that will kill the suspended algae, but not harm life, and need cleaning once a year, and bulb replacement every 1-2 years 3. balancing the pond with the right mix of plants (at least 75% of the pond planted) to fish (stock it only at about 25% capacity) If you have a spot you can make a bog filter, this is the absolute best way to balance a pond and keep it healthy. In the meantime, add plants, and use a natural product like Barley and Peat Extract. BREX

You need to wait at least 3 full days between doses, and we recommend at least one partial water change during treatment. Once you have cleared up whatever algae issue you were having, you can treat again as soon as you see algae start to form again, but no sooner than one week. BREX

Frogs yes, moss, shouldn't. Do not use this with any amphibians, crustaceans or mollusks. BREX

No. Turtles require weekly 50% water changes. Lighting should be on about 8-10 hours, and they should not be overfed. Follow these basic care requirements and you can easily control the algae. BREX
