... tiles. Pete. Not sure what a battern is, but what I did with the 240 gal aquarium was put a chunk of 2x6 under the main legs to spread the load, then also put a 2x4 running along the floor to tie them all together...

... sump pump for circulation. Dosed from 8.4 down to 6.0 with hcl (about 2 ounces). Tested water at 6hrs- 6.0 or less. Tested at 12hrs, 6.0 or less. Then, today, 24hrs later, it's back up to 8.4. This is just top of water in PE 100gal tank. So, it seems like my top off water is the source of carbonates. ...

... a good supplement but can't be the only feed. I have been experimenting with silkworms to try and get the same or definitely more protien value then commercial fish feed due to the GMO soy available and its amazing how good it works.

... on the faster you'll be able to get the pH lower. Denitrification would likely lower the pH so if there is a lot of this going on in the system then that could drive the pH up some. Look for areas that aren't getting enough oxygen but if you plan on stirring them up make sure you disconnect ...

... in an effort to get more flow. If you could do that and just let it run over instead of worrying about getting an output flow to match the input. Then just extend the RFF drain line somewhere outside to do clean out.

you are certainly proof that you can live with a pH 8 system Pete...... If you are going to put a few fish in then running it on fish water will help make sure the bacteria is in place in the media. you have very low ammonia at the moment. Else just hit it with a dose of PF and ...

If you use a 'levelling tube' or equaliser line then the tanks must be the same height whereas with the slo they can be any height difference. I would still put valves in the inlet pipes, handy if ...

I've done mops in there, but find hand breeding quicker and easier.
