Rated 5 out of 5 by from Wow!! Our local water has had algae bloom as bad as it's ever been. I have not had a clean tank in a couple montgs and I'm a clean freak. This destroyed me! I did small frequent water changes- 75% water changes. It got so green and cloudy 2 of my fishes died! I was at a point where I felt like I had the greenness u fer control but cloudiness was still put of control! I used it yesturday and woke up w a pretty darn clear tank! U am super happy with the results considering nothing else worked!!!

Rated 4 out of 5 by from Takes time to work Used this after doing a major overhaul of a 100 gallon fish tank system. It took the 36-72 hour time frame to work. Yes, makes the water look cloudy but that is typical of any clarifier I have ever used. After the time frame the tanks were crystal clear.

Rated 1 out of 5 by from Didn't work in my tank After adding the amount suggested for my 40 gallon turtle tank, the water turned black. I changed half the water and the water was a little better. Within 4 hours my 9 inch plecostomus was dead. So far the turtles are okay. I'll need to do another water change today.

Rated 1 out of 5 by from cloudy...looks like my fish are smoking Why is it that when the product was used it looked like my tank was filled with smoke? The water is NOT clear...its cloudy/smokey appearance is unappealing and concerning.

How much time has to pass so i can pure more liquid to the water again?

Asked by: vdelgado21
It is a slow moving product, so wait 72 hours before dosing again. Make sure you check your filter media regularly in case it clogs. Also, if you water is super soft (less than 3 dKH or 100 ppm) you may want to buffer it up. BREX

How many drops do you pit in the tank in a day?

Asked by: vdelgado21
You dose once every three days at most for two doses. It would be one teaspoon per 10 gallons of water, 1/2 a teaspoon for 5 gallons. BREX

Can I use it the clarified the next day after the first day if  it didn’t work.

Asked by: Kristian
Wait 72 hours then re-use. This is a slow acting product so it may still be working after 24 hours. If it works too quickly, this can cause an oxygen issue in the water. BREX

When I put this in would I need to change the water first or/and take the fishes out before I put the treatment in??

Asked by: Joma
We would definitely recommend doing a small partial water change first, and letting the tank settle down afterwards, then dose it. You do not need to remove the fish, however. BREX

48-72 hours is usually the recommendation. This is a slow moving product, so give it at least 48 hours, and check your filter media. Make sure it is not clogged. Replace it if necessary. BREX

Hi - I changed the water in the aquarium and added the prescribed amount of Clarifier. It's been 4 days and the water is still cloudy. It seems I can add some more Clarifier per the posted Q&A, however, do I need to change 20% of the water first?

Asked by: Rose2662
That depends on how long the tank has been set up, and what is causing the cloudy water. If this is a brand new tank - less than a month old, then yes, I would recommend the partial water change first, as it could be due to something like an ammonia spike. Also, if you have not tested your water quality recently, you may wish to do that first to ensure you are treating the cloudy water correctly. For water quality issues, you would not want to use the Water Clarifier, but Bio Spira Freshwater Bacteria, instead, for example. BREX
