mini sponges

[mk_ultra]

Just wanted to share this with everyone. These little sponges work great in small 2 gallon tanks and such. They are very well made and inexpensive. After a long while, the seller has posted them for sale again. So if you are looking for a nice mini sponge try here:

David,
At 1.5" width, yeah, it's pretty small and suitable for plastic breeding tanks. Simple enough for weekend DIY projects, if one is so inclined, but US$11 is reasonably priced to forgo all that work.

I have used the Hydro #0 (2”h x 2 3/4” diameter) in plastic shoeboxes for many years with great results.
They are available from JEHMCO and he also carries replacement parts for the enitire Hydro line of sponge filters.

There's a cheap brand of airlift-powered sponge filters sold here in Singapore. I got them for S$1.50 each, that's basically less than 1 USD per filter. They're cheap and pretty efficient, but there's no top attachment to channel the water out onto the surface level. The water basically goes directly upward. Still I suppose a little DIY with a 90% joint would do decently as the top attachment.

However these are smallish filters, meant for small plastic tanks, say up to a gallon or so. They're great for fry-raising tanks though.

JY, you talking about this one?



Don't remember the price exactly but it is about 1-2 dollars SGD. I love the simple design. Which make it easy to clean also.

Yup, that's the tiny fella. Very good in smallish tanks.

Ya ya. I help Bill bought some and had them posted to him before. I will use two in bigger tank and have them install diagonally. I think two small one is better than one big one due to the flow of current it generate.

I love the simple design

Kee Hoe, I used to run alot of these and while the design does work, my gripe is that the suction cups keep failing. Modified a few, standing on a stone base instead but in the end, gave away most of them when I was clearing the tanks.

Ron, i had that problem sometime also. Just dont pull too hard.
