Greenteam Posted July 27, 2014 Report Share Posted July 27, 2014 Setting up my first large shrimp tank and it's going to be a 40g breeder. Since I never setup such a large tank for this I'm not sure as to how much ADA soil I will need for this volume of water. I have one 9L bag of Amazonia but I know I will need more just not sure how much more. Quote Link to comment Share on other sites More sharing options...
High5's Posted July 27, 2014 Report Share Posted July 27, 2014 I'd think one more 9l bag would do it maybe an inch layer of lava rock to bulk it up, you could always get 2-3 more bags then you have extra. Quote Link to comment Share on other sites More sharing options...
h4n Posted July 28, 2014 Report Share Posted July 28, 2014 I used 3x 9L bags of amazonia for my 40B to make about 3"-3.5" thick substrate. So that as a reference. Quote Link to comment Share on other sites More sharing options...
Soothing Shrimp Posted July 28, 2014 Report Share Posted July 28, 2014 From my very limited experience, I have found large tanks are a trade off. Large tanks provide a much larger volume of water to have stability in parameters. If anything goes wrong, you can fix it before ti cause a lot of harm. Also, water changes can be much fewer. However for me, it also meant much slower breeding. I *think* that is because the shrimp have a problem finding who molted in such a vast area. In fact, I just tore down a 20g neo tank to put them back in a 10g, because breeding slowed down to about a 1/4 of what it was for as few shrimp I had in there. --- I wonder if you could have the best of all worlds? Sure, you could use a sump, however by using a divider with water flow- you keep the param stability, while containing the area for better breeding?

Greenteam Posted July 28, 2014 Author Report Share Posted July 28, 2014 I have been reading similar experience with other breeders about large tanks. My goal is to have 2 dividers to provide 3 sections for selective breeding. I have the option of using a 40 breeder or a 30 breeder. If I go with the smaller one the 3 sections would roughly be about LxWxH of 12x18x12. Quote Link to comment Share on other sites More sharing options...
Soothing Shrimp Posted July 28, 2014 Report Share Posted July 28, 2014 Considering a tenner is 10 x 20 x 12, the dimensions would be pretty much spot on. Have you figured out what to use for dividers? Quote Link to comment Share on other sites More sharing options...
Greenteam Posted July 28, 2014 Author Report Share Posted July 28, 2014 A tenner would be good, but I don't have any laying around lol. I have used plexiglass as dividers in the past. Use a 2" hole saw to open up flow and cover it up with ss mesh. I have wanted to try glass panels from Lowes but not sure if it's too thin. I do have a 3" hole saw for cutting glass that would work nicely. Quote Link to comment Share on other sites More sharing options...
Soothing Shrimp Posted July 28, 2014 Report Share Posted July 28, 2014 Sounds good. I think it may be wise to still put a sponge filter in each area for movement and O2, no? Quote Link to comment Share on other sites More sharing options...
Greenteam Posted July 28, 2014 Author Report Share Posted July 28, 2014 each section will have a sponge filter + UGF + one Eheim with intake and outflow on either ends to for a flow. Quote Link to comment Share on other sites More sharing options...
Soothing Shrimp Posted July 28, 2014 Report Share Posted July 28, 2014 Cannister makes sense for looping. Are you hooking up the ugf to the sponge filters? Quote Link to comment Share on other sites More sharing options...
Greenteam Posted July 28, 2014 Author Report Share Posted July 28, 2014 I just use the normal Lee UGF with airstone, and the sponge filters are the duel sponge ones that stick to the wall. The simpler the better for me. Quote Link to comment Share on other sites More sharing options...
Soothing Shrimp Posted July 28, 2014 Report Share Posted July 28, 2014 I love the double sponge filters. It would be even better if they had a weight and stand for them though. Mine occasionally pop off the glass. Quote Link to comment Share on other sites More sharing options...
randy Posted July 30, 2014 Report Share Posted July 30, 2014 I have tried many times with larger tanks and dividers, unfortunately it never worked for me unless I completely seal off to create isolated sections (then it's just like multiple tanks). One issue is no matter how hard I tried, shrimps will find a way to get to the other section. So if selective breeding is your goal, you want to try better to avoid this from happening. Good luck and hope it works for you. Quote Link to comment Share on other sites More sharing options...
