29g sump questions

  • We are currently upgrading MFK. thanks! -neo
you can use acrylic and you can pick up sheets of it from home depot,rona

a glass store usually sells acrylic and glass and they can give you the sizes you need i find crystal glass more expensive for acrylic then glass .

the home depot out here had better prices for acrylic but totem was the cheapest for 1/4 acrylic and crystal glass was the cheapest for glass.
 
This is exactly how I built my sump, and it works great. I was going to go with acrylic for the dividers, but went with glass instead. Glass to glass bonding with silicone works, where silicone won't bond to acrylic. Glass was also about 1/3 of the cost.
 
im facing a dliemma right now, i have a choice to use a 20g long or a 29g that is shorter in width but taller however barely fits under my stand. Would a 20g long be sufficient on a 100g? currently i have an eheim 2217, 2213 and an ac 70 on the tank? what would you guys suggest?
 
the thing is i have a 20 or 29 sitting around i dont want to spend money on a new one
 
Either way you still need to buy materials for the sump and plumbing, media to fill it, and a return pump. if you go with a DIY style sump (using a rubbermaid container), you're only looking at an extra $10.

But I understand trying to mke use of what you have.

You may be able to get away with the 20L, but it will be cutting it pretty close. the reason for the larger size is to accommodate the water that will backfill into your sump when the pump is turned off. Depending on the operating water level in your sump, and how much water backfills into it, you could be looking at a soggy floor if your sump tank is not big enough.
Personally if suggest sticking to the 25-30% "rule". But I'm sure there's a way to use your 20L if the proper precautions are taken.
 
ive actually decided to go with the 29 for that reason its taller but i put it under the stand and it fits perfect. thanks for the help
