Got my new setup about a third done and have some problems that I;'m just going to have to work around unless someone can make some suggestions.
original plan called for a 5x6 foot waterfall and according to calculations this would require a 16oo gph pump
I settled for a 1200 as I wanted a very slow flow.
Couldn't have the waterfall 5 feet high so settled for around 3 and it works fine now with two problems.
I had to throttle back the waterfal so excess water is diverted back to the aquarium which mean the flow is way too strong. I'm using a spray bar to divert the water, I expanded it the entire length of the tank. Six long now with 25 holes and still seems way too strong.
I was going to heavily plant the 150 aquarium but can see a lot of problems with the current and CO2 loss.Maybe I should just forget submerged plants??
I was going to use a very rich substate for Aponogetons
and aquatic ferns for the background but don't see how now.
Any suggestions here??
Another problem is the stream that recieves the waterfall
It is 8 inches wide accross the entire back of the aquarium.
Was going to use black lava rock as a substrate over AV soil but way too much current.
Do you think long fibered sphagnum over red lava rock.??
Shouldn't restrict the flow and provide a good planting media but I suspect it would break down rather quickly??
i think a 800 gph pump would have been more than needed
but I have all the mechanics setup now.
Hopefully I made myself clear?? lol.
