BOYD Chemi Pure Blue 5.5 Ounce 156 Gram

Good product, I thought my water was clear before I used this product however you can definitely notice a difference after using this product within 24hrs. I’ve seen some reviews regarding the fact the product was shipped “damp/wet” I am within the understanding that the product needs to be shipped like this. If you receive the product dry then send it back.Make sure you rinse the product before you use it. The instructions are clear in the product anyway.All in all happy with the product seems to be doing what it’s designed to do!

This stuff is unbelievable. The first time I brought some I put it in my filter and within matter of hours my fish tank very crestel clean water.so now I just brought another 1 allso I told my son about our good This stuff is and he as just sent for the stuff to try.he will be very happy with it as I explained to him. Its the best stuff I have ever used for my fish tank and I will continue to use it.i wood recommended any body to use it or try it at least so I am diffintley going to give this a 5 star.

Brilliant stuff and makes the water crystal clear…even tho it’s also for freshwater it works better in a reef aquarium…. Highly recommend

received the item and it had already previously been opened. No security seal and the bag was soaking wet. very disappointed and will not be buying again

WOW. I never knew a filter substrate this good could exist. No exaggeration, I put a bag of this inside my filter and the water has been crystal clear for months! I use this in my freshwater planted tank although its normally used in marine aquariums and I haven't needed to clean my aquarium at all. Everything just seems to cycle much better and no casualties fish wise. So impressed. Buy this, it will save you so much headache!

Yep 100% made a difference.Make sure you wash it first as per instructions and place it in the canister at the last point your water hits before going back into the tank.Within 8 hours I saw a difference in a clearer tank. Let’s see how long it lasts.

Been using from the start alongside others , I wouldn’t stop using following successful reef keeping

The seal of the container was loose, it looked like it had been used previously as wet. It's too expensive, best to just buy carbon and rowaphos and put in a reactor.

This product does exactly as advertised and for the cost was a great deal. My tank water immediately had a more polished look and was crystal clear. I also noticed it cut back diatom algae growth for about 3 months which means it was working to remove phosphates and other impurities that algae feeds on. Highly recommend.

Works for my nano.

As many have stated I received an already used package. The product is still soaking wet as if it was removed from a tank washed off and returned and no seal.

its ok. Elite seems to do a better job im my aquarium.
