Powder versus fluid additives

Having to purchase marine aquarium additives can become very expensive, so which should you go. In my opinion i have come to the conclusion that Powder is the way to go! why?
It's cheaper and seems to make more impact. It just seems to me that with a fluidised additive you are paying for the service of RO mixed to the additives, yes it is easier to use, but is it worth the extra cost? I think not. I would think that the shelf life would be longer also although i can not prove this.

Do be careful also when purchasing these additive to the amount they raise for example my magnesium is low, so i went out and purchased a additive that raises this in fluid form.
Big mistake as it is really only raises it slightly. If this level was at a satisfactory level then this product would have been fine as i would be able to correct it slowly.

If i had red the instructions properly and had a better understanding this mistake would not have been made. The lesson i learnt was to properly read and understand the instructions.

I also use powder because it's cheaper. I am not sure what additive you are looking for exactly but you can find what's call "ph adjustment rock" you won't need additive anymore.
It work great and last for over 15 years.

I just love that!

Understanding evaporation and top up

Many new Reef Keepers get confused and stuck when it comes to topping up water in their Reef Aquarium. It is really simple and easy to understand. It doesn't need to get confusing.

Evaporation happens continuously, many new hobbyists start by adding Freshly mixed saltwater then end up with a really high salinity. You have to think of your water as two elements, in fact it is. Salt and Reverse osmosis water. Salt cannot evaporate because it is a solid and solids don't evaporate. Therefore as the water evaporates, the salt remains in the Aquarium, which in turn increases your salinity. From this you should have worked out that Top up/RO water should be added.

If your Aquarium is left for a few days or more the salinity will rise rapidly, which is why it is important to top up daily if possible.

When carrying out a water change, because you are removing the mixed salt water your are removing both elements, salt and RO water. All that is required now is a fresh saltwater mix that…

The Reef Aquarium With Low Magnesium - What Can Happen?

Hopefully you will understand that keeping corals is a huge responsibility and can become very expensive to yourself and the environment. Corals are very interesting animals and unless you are willing to nurture them properly, you should find another hobby.

After checking the usual, Salinity, Nitrate and Phosphates. You should be checking Magnesium, Alkalinity and Calcium. These three parameters are very important when keeping short polyp stony,and long polyp stony hard corals, SPS and LPS respectively.

So what effects will low magnesium have on your reef aquarium?

You will find it very difficult to maintain high alkalinity and calcium levels if magnesium is low.

Corals will slow in growth and will cause some corals such as Duncans and torch corals to recede, and in some cases die. You may as many other reefers do, think you have something unseen and/or unheard of eating your corals, because branching heads or receding one by one. Don't get fooled by this, it more likely be the cas…

New V2 Auto top up from TMC

After needing an auto top up unit for some time, with quite high costs for a unit that function seems very minimal. I have always been put off until now. Whilst reading ultra marine I saw a review and advertisements for the TMC V2 auto top up and more surprising is it's very affordable price tag. After further investigation it seems to have really good reviews on forums and blogs. I have to say it is a real good, easy to set up and cheap unit that functions perfectly. This should give me more stability and time to enjoy the aquarium.I will in a few weeks report back any improvements that it will hopefully make.
