If your media stays wet, your BB will stay alive for days, weeks and even months. Never a worry there.Rhobbs521 said:Also with power outages if it’s too long wouldn’t a sponge filter be more likely to keep the BB alive than a HOB or canister?
Hey I have a question if I needed to remove medicine with sponge filters how would I go about using something like activated carbonIslandvic said:You can also look into putting sponge filters in the back corners instead of HOB's or canisters.
Take a look at ATI Hydro Sponge Filters. I use them in my tanks and I like the brand a lot.
They have a modular design and you can stacked them together.
Their "Pro" models use coarse foam sponges for high flow applications and their regular models use fine foam sponge.
You can buy 2 Hydro Sponge IV's or V's and 2 of the same Pro versions.
Stack the fine foam ones on top of the coarse foam models.
Then throw a power head on top, such as an Aquaclear 70 powerhead. That would give you 400gph flow through each sponge tower.
Kensfish.com and Jehmco.com has the best selection of ATI filters and spare parts/adapters.
To stack them, you need to buy extra "bulls-eye" & "step" pieces.
American Aquarium Products also has a large selection of ATI products l, with tons of pics and extra info. ().
If you lookup the "Prime Time Aquatics" YouTube channel, Jason primarily runs ATI sponge filters in all of his tanks in his fish rooms, even his 150 gallon tank.
Look for his "fish room tour" videos and you will see them everywhere.
I love sponges I use them in every tank I have instead of cartridges on my HOB.Islandvic said:Also, there is the SunSun 704B.
You can get them without media for about $70-$80 online.
It would be better to buy your own media to customize them the way you want.
If you get 2 of them, the 1st can be filled with layers of progressively denser foam sponge layers with the top basket full of PolyFil batting.
The 2nd canister can hold your foam sponge and floss layers, biological, crushed coral (if stocking African cichlids) and chemical filtration.
Dont underestimate how well layers of foam sponges will colonize your bacteria.
Thanks good to know! I love sponges because of the mechanical and biological filtration. Plus the pump and two filters will be a quarter of the cost of a good canister filter.Islandvic said:Probably a series of 50% water changes would clear out residual meds.
What doesn't clear out from PWC's will disapate on their own naturally, depending on their half-life.
