Wow excellent post.
Read it from start to finish.
Gives me some encouragement.
I was planning a wooden tank build for this summer, now I will have a look at concrete also.
The Outdoor section of the Pond where the filter section have now been upgrade with roof now. The roof is the thin Metal type with a layer of foam insulation to keep the heat down. Several section of clear plastic roofing sheeting was also placed in 3 sections so that the enclosed space would be brighters.
Photos show before and after the roof was added. The new roof covers the entire side of the fishroom and a little bit of the front section.
During a recent Fish exhibition a number of new fishes was added and will update in the next few postings. However added 2 non water pets to the mix. Hope you like their photos. Still young at 2 and 4 months. Pond Watch Guards to be exact
A better and clear view of the New roof. The place is about 13' wide
and have planned to put a number of smaller tanks for the other fishes but seems i have changed the idea and would be moving those tanks inside and leave the outside filter section relatively clear.
