Can I run a mixed reef tank with only two HOB filters (for filtration)?

[MoshJosh]

I am sure it has been done (HOB only), and feel free to link me to threads/post pictures, but I have been toying with the idea of running a "bigger" tank (40 gallon) with two Tidal 55 filters. One as a standard HOB and one as a DIY refugium. I would still run a heater, wave maker (probably an oversized gyre), ATO (mechanical float valve), and a dosing pump. . . it would be ugly sure, but that has never stopped me before. . .

Why would I want to do this? I don't know. . . for the "challenge" maybe (might be easier than I am thinking)? . . for simplicity (FEELS simple, but would it be? I don't know)? For giggles?

Not really sure but it has been on my mind for a minute. . . I have an 11 gallon reef growing SPS with only HOB filtration (technically I added an air powered skimmer recently but that was for CO2 scrubbing purposes/experimentation).

Just sort of brainstorming in thread form. . . anyway, what are your thoughts?

EDIT: I guess it seems like an answered my own question "I have an 11 gallon reef growing SPS with only HOB", but I do big water changes in that tank, even if I am just siphoning the junk off the bottom I end up taking out about 25% of the water. . . I would not plan on doing 25% weekly water changes on a 40 gallon. . .

I don’t see why not, it just means slightly different maintenance than a system with a skimmer or other export means.

weekly water changes are game changers if you have the dilligance to keep up with it.

However most in the hobby can only do it for so long before cost / effort runs out, and then ends up letting it go to a mess, which then it cross a point of no return, and they give up on the hobby afterwards.
