Hiya - just starting out with aquascaping, trying to keep to a sensible budget (initially, at least!), so not C02 straight off the bat. You can obviously muck around for weeks with hardscaping, but you have to stop somewhere and start with the rest, right? So...any thoughts on any humongous mistakes that are being made here? My tank is 60X50X40cm, running off an Eheim Ecco 2232 filter. 36W Nemo lights. LONG term plans call for C02, but not right now. Thanks!
