Filtration on my 70 gallon

[njr_]

that is one of my modifications, I also double sponge, and one advantage having MTS ( multi tank syndrome ) with just having the same filters, means less spare parts to buy, I bought a 6 pack of replacement sponges, for the Tidal 75's, so I could double sponge all of mine... having multiple brands or sizes of filters is not as practical, and cleaning the dirtiest sponge keeps good bio going... also, as sponges plug up, they filter finer particles, at reduced flow... which is also why I modified mine to flow more...

Thanks mate, last question have you ever had an aquarium from diversa. Seems very well priced and has good reviews looking at getting the 250l one.

I think right now you're talking with a Canadian and an American on an international forum. You'd need UK responses for tank brands.
