parrdog Posted June 12, 2004 Share Posted June 12, 2004 G'day All, Just wondering how good you think Ehfisubstrat is? How does it compare to Seachem Matrix? Thanks for the advice, Jamie. Link to comment Share on other sites More sharing options...
Barca888 Posted June 12, 2004 Share Posted June 12, 2004 Well i suppose if one provides a larger surface area to colonise it should be better. Just look at their details. Link to comment Share on other sites More sharing options...
Mazimbwe Posted June 13, 2004 Share Posted June 13, 2004 Hi Jamie, to me it looks like you are comparing apples with apples(sorry Gwenyth ) and wondering which tastes better. You are, after all, comparing the two top of the line products rather than a Top V's Cheap alternative. The two products you are looking at are the best of the best, IME, and the comparison is a hard one too make. Both will do an excellent job with bio-filtration and therefore, maybe the other factors of cost, availability, etc...are important in your descision-making process.

MoliroMan Posted June 13, 2004 Share Posted June 13, 2004 Hi Parrdog! Eheim substrate pro is meant to be better than the others because it claims to have a larger SA for bacterial colonisation. I use it in my filters but in all honesty can't tell if it is any better. But i know it is quite expensive. U get a free box when u buy the Eheim Prof II 2028.

Nornicle Posted June 13, 2004 Share Posted June 13, 2004 plus you have to replace it, i reckon I would only use it in a canister in a marine tank or a very high waste tank, and even then you'd have to use it in large amounts its very good IMHO to us in low volume filters like eheim canisters, where cost per litre of filtration space is very high...

Jim Posted June 13, 2004 Share Posted June 13, 2004 I prefer seachem pond matrix in my filters - beter surface area IMO plus u never have to change it. Link to comment Share on other sites More sharing options...
anchar Posted June 13, 2004 Share Posted June 13, 2004 Yep...I'm with Jim on that one. If you have the cash and need a large amount, buy the large bucket as it works out to be heaps cheaper than the Eheim matrix merjo Link to comment Share on other sites More sharing options...
parrdog Posted June 13, 2004 Author Share Posted June 13, 2004 Thanks for the comments everyone, we just had a great win at soccer, I got man of and we celebrated with about a thousand beers. Gotta love that! Link to comment Share on other sites More sharing options...
bob12369 Posted June 14, 2004 Share Posted June 14, 2004 I use Sera Siporax in my filters, it is a ceramic quartz glass like Ehfisubstrat but in a ceramic ring style, it provides as good a colonisation area and has a better water disbursion through the cannister than Ehfisubstrat & you never have to change it.

Guest Gutty Posted June 14, 2004 Share Posted June 14, 2004 What are normal prices on these 2 items ? Just an FYI for anyone interested, i've found Majestics price of $25/litre the cheapest Matrix around. If anyone knows of a better price i'd be interested to know.

CThompson Posted June 14, 2004 Share Posted June 14, 2004 Contrary to Ehime’s claims that one needs to replace Ehfisubstrat, I have used it for years, with no ammonia/nitrite issues. I know of a professional retail aquarium who has also used it for years, with out replacement, with no issues. At worst, you may need to clean it in aquarium water to remove dirt. I believe Ehime’s claims of Ehfisubstrat needing periodical replacement are based on their requirements for staying in business. I’m sure that Ehfisubstrat does lose some effectiveness as time passes, but I am equally sure that if you have enough Ehfisubstrat in there, the lose will not be relevant to maintaining the tank’s continued cycling. In regards to the difference between Ehfisubstrate, and Matrix. The prime difference between the two is that as Matrix has a larger particle size, it is reputed to have an effect on the tank’s nitrate. Being of a larger size, the outer areas are colonised by aerobic bacteria, which strip out the oxygen, and by the time water passes through to the centre of the Matrix, it is devoid of oxygen, which allows anaerobic bacteria to exist, and feast on the nitrates. Also, due to the size difference of the two, sometimes one is better than the other dependant on where it is going to be used. That is, for example, you can pack more Ehfisubstrate into a canister filter that you can with Matrix. Craig Link to comment Share on other sites More sharing options...
