Greenhouse aquarium

Hi, I cultivate hard to find marine macro algea, sea grasses ect.

prices range from $1-$10 depending on rarity ect

let me know if your interested

Something else you might consider for cooling during the summer...

Bring all the sprinkler water for your lawn through your greenhouse first and use it to help cool your tank.  Maybe put a coil of tubing into the dug-out sump that the water going to lawn can flow through?  You could set up a controller to start the sprinklers when the tank water gets above a certain temperature. 

I have had this thought that if I ever really get into this hobby like some of you, and if I have the money. I would like to build a huge tank something in the 300 to 500 gal range maybe bigger. On that tank I would have a refugium pond that would stretch out on the floor in front of the tank. This pond would be a great place for me to keep salt water plants and even Halloween crabs.

You ever think about adding a small pond to your new setup? Something that would allow for crabs to walk onto land. 

Chris thats an interesting idea. Where could I get holloween crabs? They would do ok in saltwater, right? I still have about 50 square feet of space I can use for whatever.

Thanks Corwando. The foundation was a pain, but its good knowing the tank is on stable ground.

I have seen the crabs at fish 4 U. I think the crab in Skyetone's picture is of one. They don't do too well in fresh water, since they are salt water crabs.

If you do something like that I will have to come and check it out. I could even help you out if you needed some help.

So if I had a pond how would I connect it to the system without the water level changing? I would only want the sump water level to decrease.

Would the easiest way be to add an auto top-off system for both the sump and the pond?
