Very nice setup! For the two of them they are fairly similar; keep pH up as to not chemically erode the shell and feed them well. The B. Pagodula seems to be IME more picky about flow, so an additional air stone is beneficial, or cranking up the air flow in a sponge filter will work. On top of that, they are not the biggest fans of a brightly lit tank, so that's why I keep the mother crypts in the tank to provide shaded areas. If you take a look at my shrimp tanks (20L's) you will see I run dual sponges. This isn't because the shrimp are dirty (though they produce a ton of waste which no one seems to note) and it isn't to provide surface area for them to graze (though it's beneficial) it's so I can have flow. In all my shrimp tanks I have the air cranking in there to the point it's pushing the limits of flow on the filter. You have to oversize the filters to get this kind of flow, otherwise you're putting more air in which is creating less vacuum to pull water through. If I were running two sponges rated for 10 gallons each to meet the 20 gallon rating logic the sponges would be useless for filtration and literally just be weights holding the airline down. Since my tap doesn't have chlorine I don't clean sponges with tank water. I purge the sponges weekly till no mulm or tinted colored water comes out. Some would think this is the worst thing that can be done, but with an established tank this isn't an issue. The tank has substrate, plants and a second filter to keep up while the other re establishes. I never have any parameter swings with this process and never crash a cycled tank. I'm also heavy on water changes. The tanks not only get a filter cleaned weekly, but on average get at least a 50% water change. With that water change I'm topping off with half or more with remineralized RO/DI and the rest is tap. I'll segue a little more into sponges. Sponges shouldn't be chosen for a tank based on the 'tank size rating' you need to spec them for the flow you need in the tank. Obviously to those who want a show tank, space is a premium, aesthetics are towards the top of concerns and to follow my method would not be visually appealing or looking naturalistic. I'm setup solely for function over form and squeeze in form where I can. I'd rather have two large sponge filters in a tank rather than a small single one with the addition an air stone or a HOB with a sponge. Why? Because air provides the flow I need. Yeah I could get it with a powerhead or a HOB, but I don't get the simplicity of biological filtration that sponges offer. I also run finer sponges because I want them to gunk up and provide some mechanical filtration. Having two means I can alternate sponge cleanings weekly. I also aim for a lot of tanks to have limited outlets per tank (OPT.) When keeping multiple tanks, or a fish room in my case, OPT needs to be low. If I had the space and time to do it right I could thin out plugs by not having one light per tank, but to do that I need to change the stand and that's a multiple part challenge that I've covered. In my case, the easiest way to reduce OPT is to power as much as I can with air. 1 Link to comment Share on other sites More sharing options...
