hi everyone fairly new to this hobby.
I had a 20 gallon for about a year.(never did anything special with it) Then got my hands on a 90g, its been setup for a couple of months now, but the setup needs some tweeking. I have a couple of fish couple of guppies, a dozen or so daimen zebra, 4 playties, one of those suckers, 2 snails, very lightly planted with some large driftwood. for filtration I have a rena xp1 and xp4. so now for the questions
I am planning to change the substrate. my plan is to kneed in some laterite with potters clay and then flatten that out on the bottom. then top it off with some pea gravel. kind of thought about this after reading about the clay fertilizer balls.
1) Has anyone tried this?
2)How much laterite to use?
the xp4 is not setup yet(just got it).
3)what would be the best placement of the input and outputs(xp1+xp4)?
4)Spray bar or nozzle?
5)should i get a power head?
6)and how many gph?
thanks in advance.
