Transitioning from High Tech to Low Tech
I currently have a 40 Breeder that has moderate light (2x20"-T5 HO's and 2x48" T8's hung 12 inches above the tank) CO2 system and EI dosing. I had to move down to the 40 from a 55 do to space in the house. Good news is we're moving to a new house with more room and I plan on setting the 55 gallon back up. We move in 6 weeks and right now things are really busy with working on the new house, and will continue to be after the move, so I'm not going to have as much time to spend on my tanks for a while. My plan is to set the 55 back up after the move as a low tech with my 48" Coralife T5 NO and I just won't have time to do militant weekly water changes for a bit. None of the plants I have are high light with the exception of the Blyxa japonica. I'd like to keep a big low tech tank and maybe focus on a nano high tech once things get settled down in the new place, so I'd like to use the CO2 rig on there and maybe do some light Excel dosing (or not) on the big tank. So do I gradually shift the lighting, CO2 and dosing on the tank now or just move everybody and start the new cycle then? What kind of dosing do you do on a low tech if you want fewer water changes?
I've been doing EI dosing on my low light (1 T8) 10 gallon with no CO2 and weekly water changes and all the plants have been doing really well. When I've been slacking the past few weeks and letting my water change and dosing go a few days the crypts get pissy and java fern turns brown. Funny, I thought Java fern was pretty indestructible.
Thanks for your input!
