Hi there, I dont know if i should have put this in Planted thread or here, as it deals with Fish and Plants, or can i put this thread in both places, but here goes nothing:
My setup would be low tech lighting (shop lights) in a 75G tank with a Eheim 2217 as primary filter, and either an eheim 2215 or preferably an Aquaclean HOB 110 (or maybe a bit smaller). I will try to do medium to heavy planted, with low light plants (max medium light), such as hornworth, anubias, java moss, vals etc... (compatible with the fish bellow), playsand substrate
Why two filters, and specially the HOB as second? Because i will have very messy fish, ie: 6 fancy (slow) Goldfish, 2 Bristlenose Plecos, and either 3 dojos or 12 white cloud minnows or 6-8 fancy guppies. I have been told in forums this is not yet overstocked, specially if i do weekly 50% water changes. I may not get this many fish, but i want to plan for it in case this is reached. I may put smaller fish in a 10g tank eventually too..
Why my concern of the HOB, aquaclear 110? Because it puts alot of bubbles in the water, thus removing alot of CO2. (this is what i have read anyways.) I will add the general liquid fertilizers (not the one that has only CO2). My fish will be more important than the plants, but still, i care for both. Right now i have a small 10g with aquaclear 20, and without fertilizer, hornworth seems to be growing very well, and so is the java moss, but not the anubias does look as it is doing too well (maybe needs fertilizer). Instead of the HOB, i may be able to get a smaller size used canister for like 70$, so this is an option as well.
Pls let me know your thoughts on the HOB as secondary filter, or if it is even necessary, for the fish load mentioned?
