Aquasoil or inert?
I'm getting pretty close to adding water to my 10 gallon Dennerle Scaper's tank. I plan to use tap water, since I'm already hauling 5 gallon buckets of RO from my shop more than I'd like for my previously set up matching tank. My tap is on the soft side, about 2-3 KH, 6 GH, and 120 to 150ish TDS. Just how much is this going to shorten the life of aquasoil? I have bags of both red Eco complete and Dennerle (produces NH4 like ADA) Shrimp soil on hand. I seem to see as many people as not using limestone with it, so it would stand to reason that it still must go for a while when absorbing CACO3. But I plan on keeping shrimp in here and the last thing I need is for anything to happen that could kill my colony a year down the road.
The purpose of this tank is very simple: be pretty and have good plant growth and healthy shrimp. Will probably go with tigers and babaulti, which can live in either 0 dKH or harder conditions. I have most plant species I want to use already thriving in both soils and inert in other tanks. All things being equal, I'd go with the soil for aesthetic reasons and plant growth. But if I'm going to have to do a 100% tank breakdown in 18 months, that's not a scenario I want to put shrimp through. Please share any thoughts or experiences you may have. I've yet to have to deal with aquasoils ceasing to work or turning to mud as others have described, but that may be from using RO on all my tanks with it.
Nothing good happens fast in an ecosystem.
