Hey guys, picked up a 40 breeder from petco at their sale and figured since I will be building a stand for it, why not also put in a sump? I've always wanted to try it and I think it will be a good learning experience for a 100+gallon tank in the future
I basically want to figure out some of the questions right now before I build a stand to make sure the sump will fit. Ideally I would like to fit a 20H as the sump. Unfortunately the DIY stand builds I looked at all seem very sturdy but dont seem to have enough space for a 20H. I'll look for other stand builds but if not, will a 10 gallon work as the sump? I dont want any flooding issues because I didn't have enough reserve volume in the sump. Unfortunately the DIY stand builds I looked at all seem very sturdy which isn't a bad thing but dont seem to have enough space for a 20H.
Anyway, on to the sump system! First the overflow. I think I will be buying one because too many DIY things all at once is a bit too much for me to handle. I was looking at oversized ones with double bulkhead outflows with max flow over 1000gph. (they dont cost that much more than a single) I figured since I would be shooting for 400gph in my tank, I could possibly be really lucky and not get any gurgling or if I do get gurgling, adjust one of the outflows higher to make it a herbie? any thoughts on this plan?
About the actual sump, I think I will avoid a wet/dry configuration and go with a splashless style with foam and random ceramic media I have lying around the house. I dont plan on running CO2 at this minute, but I could see myself taking the co2 off my 12g long and putting it on this. Since a picture would make things more clear, I attached one. Please excuse the bad drawing and handwriting
I want to know if the baffles are acceptable and if I could fill the center portion between the pump and the fine pads with ceramic media.
Finally, should I use all pvc tubing or is it possible to use some soft tubing between the sump and the tank?
so quick recap:
1. 10gal sump or 20gal sump? If 20 gal, I think I have to find a less sturdy design for the stand.
2. overflow box: is a double outflow good idea?
3. sump: Do the baffles and water flow look okay?
4. tubing: is soft tubing okay?
