Boyd Chemi-Clean 6g Treats up to 900 Gallons - Effective Chemiclean Cyanobacteria for Marine & Freshwater Aquariums, Safe for Fish, Corals & Invertebrates

Chemiclean, wiped out my cynobacteria in three days it was all gone. I ran this for 72 hours instead of 48 hours. I have a 300g reef aquarium and it did not effect the corals, clams, invertebrates or fish. I did a 20% water change at the end of 72 hours. I also let me protein skimmer run wet and ran a line to a floor drain, this helped get all the chemiclean out of the aquarium and I replaced any water lost with freshly mixed saltwater. Very good experience with this product!

First let me comment on the person that lost all his fish and gave this product a 1 star - not sure what he did wrong - maybe put the whole bottle in or maybe he is one of those "leave negative comment" people that works for the competition or he had something MAJOR going on with his tank before he started treatment but rest assure - it will NOT kill your fish if followed directly. I've been doing fresh and saltwater for over 20 years now - my tank is a 300 gallon saltwater fish only. In the last 6 months i've been battling red slime algae - parameters are all in check - my final straw was 30% water (60 gal) every week for 5 weeks , cut my lights to 8 hrs / day , which really suck cause I never see my fish and finally cut to feeding every other day for a week (enough food to consume in less than 5 min.). My tank is far from overstocked - I have 18 fish (angles, tangs, butterfly, wrasses, damsels and a bunch of hermit crabs) - all under 4 inches and a 26" zebra eel also replaced my T5 light bulbs. Nothing worked and the slime keeps coming back. Finally researched what one of the best red slime removers were and this one came up many times. Before using I had about 65% slime coverage on my artificial coral -. Instead of a air stone as they recommend, I simply put my water return jet to skim the surface and had a power head behind it and it provided all the bubbles I needed. First dose took about 40 hrs to get rid of about 75% of the algae - did a 30% water change and added a second dose - another 40 hrs later it was literally all gone - did another 30% water change and now we'll see how long it stays away for - hopefully forever!! The product works like it should but it may require a second dose - ALL my fish are fine with no deaths not even the hermits - not even distressed during the treatment. I will probably dose once a month for the next few months just to keep the red slime in check. BTW - yes! turn OFF your protein skimmer - had mine off for the entire treatment - only to turn it back on after the second water change and it will foam like crazy - had to dial mine down about 3 notches from its normal position - so keep a eye on it for a few days afterwards.

Always have good results. Kills all nasty cyanos in two days with no recognizable effect on corals, clean up crews and fish.

I've used this product several times over many years. It always works, and I've never had any issue with it harming fish/corals. Sometimes I get by with a single dose, but be prepared to dose twice. I've started buying the larger 6g contain just for that reason.I will say, that your protein skimmer will go absolutely nuts, so be prepared to deal with that. You need to keep oxygenation up during treatment, so adjust the protein skimmer is something you probably want to keep in operation. What I do is restrict air input to the skimmer and remove the plug from the overflow cup (mine has a drain plug). Far better to keep oxygen levels high and sacrifice skimmer collection for a week in my opinion. Even after a 20% water change after treatment, you may still need to run your skimmer at a reduced rate, but at that point you can probably resume collection.

I have had a salt water aquarium (24 Gallon) for almost 5 years now and after about 1 year it started to grow the cynobacteria that began coating the live rock in red slime. It got really bad before I found out what it was and how to get rid of it. I have always used the Chemiclean product to get rid of the slime. I need to use it about every 4-6 weeks to keep the slime under control in my tank, I admit though that I only do an average job of cleaning it and doing the proper water changes which if I was more vigilant would probably cause the redslime to grow slower.I used to buy the smaller sized bottle which each lasted me about a year each but this time I decided to get the bigger one that is cheaper overall and should last me quite a bit longer. Regular use of this product, allowing with water changes, should keep your tank in check. My fish and invertebrates never have seemed to suffer any ill effects from using this product in the recommended manner.

This does what is says it does for the reef tank. If I get lazy and my calcium or alkalinity get a bit low, especially if I’ve removed too much chaeto, I get cyano. This eliminates it. Does not harm fish, inverts, corals, etc. It does make the skimmer go crazy, so be ready for that. I drain the skimmer into a bucket under my tank and it can easy overflow in a few minutes with this stuff. I will keep buying it because I am lazy frequently and corals just really suck up a lot of calcium, and this product will continue have my back.

The media could not be loaded. I have 29 fish tanks all fresh water… had a problem with the bacterial algae in many of the tanks. Chemiclean really is the only thing I have found that works exactly as advertised. I have live plants, shrimp, black worms, daphnia, live bearing fish, and rare killiefish and chimiclean doesn’t seem to harm them.
