Brightwell Aquatics Microbacter CLEAN 500ml

Worked well in my tank.

Very effective at removing cyno

I've been using this product for over 10 weeks, algae on rocks still exactly the same (Id expect at least a small difference but there’s been no reduction in algae at all) I reduced my lights to 6 hours a day and maximum 50% intensity. Ammonia - 0 Nitrites - 0 Nitrates - 5 Phosphate - 0 Very tough green algae on rocks, tried scrubbing off with toothbrush but doesn't remove anything. So I bought this as it says it will clean rocks however, this has not been the case. Waste of money, might as well have been adding water. Will not be using Brightwell products again - Disappointed.

This stuff works great! Had a problem with diatoms and hair algae. Thought about chemically treating my tank to fix it but ran across this stuff. After about a 2 weeks diatoms population diminished dramatically. After a month they are completely gone. Hair algae still persists but has not grown out of control. Also like other reviews state, my protein skimmer is working way more efficiently now. It has been about 3 weeks since I used the last part of the bottle and my tank has maintained stability. Highly recommend this product for getting past the ugly phase or naturally cleaning your tank.

I use several bacteria products. They won’t work fast but combined with good maintenance they really do work on keeping a tank looking sharp.

This stuff really seems to work! I have a bio orb and I have to tell you it is really hard to get these tanks cycled! I’m learning a lot. I put the stuff in and it’s so fast how quickly it clears the water.

Not really noticing a difference

Great product and works well just as intended
