Answer This Question

A:  DMM: Do you know the exact volume of your pond? That can be a problem with the specific ratio per gallon as I recall. My wife had two 25 gallon recirculating whiskey barrels full of gold fish cascading into each other and there was no problem that I can recall adding the Stop-Alg, but you might want to contact the manufacturer if there's any doubt as to how much to add. I hope that helps, Hank

Q:Is this product safe for dogs, cats and birds that may drink from the pond? thank you

Answer This Question

A:  Peete: I would ask the manufacturer to be safe. Dog and cat were long dead before we started fish in the patio pond and I never saw birds drinking anywhere but from their feeder in the back. We did have an algae problem, the fish survived, and the clarity of the water improved. That's about all I can tell you from my experience. I hope that helps, Hank

A:  Tjland: I would think so if you follow the directions. If in doubt I would suggest asking the manufacturer. We had plants and fish and they both survived. I hope that helps, Hank

A:  My pond is strictly a reservoir for my water feature. In the spring after a winter full of leaves in the pond the algae starts to grow. After removing the leaves this killed off the algae. It says it will not harm the plants but I don't have plants in my pond.

Q:Is this harmless to the snails in my pond?
by|Apr 26, 2018

Answer This Question

A:  Kay: That one worries me as marine snails feed on algae and other detritus material and this stuff is designed to eradicate algae and clarify your water. So what's bad for the algae may well be the same for your snails. I would contact the manufacturer or at least have a talk with someone at an aquarium. I hope that helps, Hank

by|Jun 9, 2019

A:  Kay.. The Stop-Alg product simply states; STOP-ALG is harmless to aquatic animals and plants. I assume snails would count as aquatic animals, but I'm not 100% sure. I tried to research this on-line but found nothing specific to snails. If concerned I would simply do a trial test taking a few snails placing them in an isolated aquatic environment (bowl or a pail) and add some Stop-ALG to see if it affects them.. Regards,2695hplc..

This is a review of Viagrow Stop-Alg 1000 ml Aquarium and Pond Algae Control. I got this product to help control algae in my outdoor Koi pond. It's a dilution mixture of 10 ml to 400 liters of pond water or 3/4 oz. per 105.67 gallons - treat the water weekly. The chemicals are Methylene Blue and Malachite Green. I've been using it for a few weeks and it appears to be working in clearing the algae. The bottle is a very large 1000 ML (33.8 oz.) so it will last for quite some time.

Our pond looked like swamp water until we added the Viagrow Stop-Alg. As per the instructions we diluted the product with some of the pond water in a bucket and spread it over the surface of the pond. It left blue colored streaks where we had dispersed it which quickly disappeared as the product mixed with the water. In a couple of days the water cleared. The fish and turtles seemed quite content with the result as were we. There is an indication on the bottle that this product is for fresh water only. This is a 1000 ml bottle the instructions of which indicate 10 ml of product/400 ml of pond water.

Recently started a small goldfish "tank" in a Japanese style porcelain container made particularly for this feng shui purpose. I decided to use the Stop-Alg right from the get go, and it's keeping the water beautifully clear. Of course I have aeration & a small filter, but this arrangement is outside, by my front door and does receive lots of sun, so algae was a concern. The fish are suffering no ill effects that I can see. I did have to look hard for a reference to safety for other animals and birds that might want a sip of this water and did find it in the small print on the side (which should be a bit larger and easier to find.) Generally, a very good product.

I actually wouldn't know if this product works because the company sent me the wrong item without me realizing it. I gave it to my handy man, asked him to follow the directions and put in my pond so he did. A few weeks later, I wanted to know why there was still algae and asked to see the bottle to make sure he added the correct amount. To my surprise, I realized they sent me Viagrow chlorine remover. Well, I guess that answered my question on why it didn't remove the algae. Well, I certainly don't need chlorine remover when I am using a well and rain water to change or replenish evaporated water.

I recently received the Viagrow Stop Algae Aquarium and Pond Algae Control product to try on my outdoor pond. With warmer weather approaching, algae is definitely a problem. Before using this product, our pond had developed an algae bloom which was starting to take over. It was clouding our pond, robbing it of much needed oxygen for our fish and also frequently clogging our pond filter. I poured two capfuls of this product into our pond, and within a matter of a couple of days the water returned to being noticeably clearer. It did not harm plant life or our fish and I do not have to clean the pump filter nearly as much after treating the pond. The product works as advertised. For maintenance purposes, I am now placing one cap full of the stop algae product in my pond once a week, and have had no further issues with algae. In summary, I clean my filter much less frequently, my pond is basically clear and it doesn’t seem to affect our fish. I would recommend giving this product a try if you are experiencing algae issues in your pond or aquarium.

The name Viagrow is what convinced me to try it. So far everyone of their products I've used has been a winner. Mine is a heavily contaminated patio pond combination of two joined whiskey barrel halves, pump circulated with one cascading into the other. After numerous algae blooms last year the water color was dark green. Surprisingly, our gold fish survived so I wanted to treat the condition as conservatively as possible. I tried numerous filtered tap water flushes but that didn't work. With the summer like weather we've had this winter it was getting worse so I started adding the STOP-ALG and the water appears to be clearing up. And the fish are still alive! If it eventually takes the whole bottle to do it I'll still see it as a win win situation.
