Ready to swap tanks
I plan on moving from a 40 to a 75 gallon tank and relocating the current tank's contents. The tank is a very low tech setup with pea gravel that can be seen in "Your Tanks". The tank has been in continuous operation for about 20 years with intermittent gravel vacuuming and water changes.
This is an opportunity to take a very different direction. I want to minimize shock to the plants during the transplant, and I fear that moving the gravel will necessitate losing a lot of the silt in it that the plants need. I've read a number of approaches, and it sounds like all of them do not permit the usual gravel vacuum cleaning methods. I'm OK with that, but it's been a habit of some decades to get the vacuum column out and extract the silt from open areas around plants from time to time.
I plan on having a fairly heavily planted tank, and am considering CO2 also, having bought a 48" buildmyled multi-channel LED strip and controller to give me lighting options. I'm open to any suggestions or approach on substrate, as my experience is rooted (pun intended) on what people did 20 years ago. I really have not kept abreast of new trends, technologies and techniques. I'd greatly appreciate any thoughts from the forum. Thank you very much.
